where is the OBD 2 diagnostic connector located in the Camry 40 (year) – Toyota Camry club Russia – AvtoVyzov

During the computer check, a special built-in device is used - a diagnostic connector.

At the same time, the quality of operation of the injection engine, gearbox, electronic sensors, security system and other actuators is diagnosed. Errors recorded on the electronic control unit (ECU) are analyzed.

Self-diagnosis procedure

This function is available if the climate control on the Camry 40 is equipped with a unit with an LCD display. On older versions of units, diagnostics can only be carried out using a car scanner by connecting to the standard connector located near the steering column.

Self-diagnosis procedure

We are trying to carry out self-diagnosis of the climate systems in the car, you need to perform the following steps:

1. Turn off the engine, turn off the ignition.
2. Simultaneously press the Auto button on the climate control panel and the button that activates internal air circulation.
3. While holding the buttons, turn on the ignition. At the same time, all indicators located on the remote control display will begin to blink, which indicates the start of the self-diagnosis process.
4. After checking the display and diagnostics of the sensors, an error code will be displayed on the display in the place where the temperature is normally displayed.
5. If 2 or more errors occur, they are displayed alternately, starting with the smallest code.

The climate control on the Toyota Camry is equipped with a considerable number of electric drives, the functionality of which can be checked by switching to self-diagnosis mode. To do this you need:

1. Start the system self-diagnosis process as described above, then press the button that activates air circulation inside the cabin. Important: diagnostics must be performed on a fully warmed-up internal combustion engine.
2. During the test, various fan operating modes will turn on alternately, with a delay of 1 second, and the dampers will open/close.
3. You can increase the interval for changing modes by pressing the windshield defogger button.
4. To exit the test mode for drives, relays and fans, press the AUTO button - in this case, the control unit will switch to the sensor test mode.

The diagnosis is completed by pressing the Off button.

Climate control for Toyota Camry

The climate control control unit on the Toyota Camry supports the memory clearing function. It should be carried out after eliminating errors that arose during the self-diagnosis process. It is performed as follows:

1. The control unit is put into diagnostic mode.
2. Press the front window heating and rear window heating buttons at the same time.
3. The error memory has been cleared.

There are many reasons why the climate control on a Camry 50 or 40 shows errors during self-diagnosis: from missing contact to sensor failure.

Possible malfunctions that occur during climate control operation are as follows:

• sensor malfunction. Fixed by replacing it;
• control unit malfunction. Often, to fix the problem, it is enough to simply disassemble it and solder all the contacts;
• Damaged electrical wiring or sensor connectors. This often occurs as a result of unqualified intervention in the electrical equipment of a car;
• weak compressor drive belt tension or damage. In this case, you need to check the integrity of the belt;
• failure of the electromagnetic clutch sensor installed in the compressor;
• compressor failure or blockage;
• leakage or lack of refrigerant, or its level does not correspond to that established by the car manufacturer;
• lack of contact with the instrument panel or engine ECU.

It is also worth noting that the climate control on Camry 40 or 50 must be diagnosed in a well-lit room or outdoors - otherwise a light sensor error may occur.

The most common indicators

Fuel problems

This error has code value B 1206. Errors, according to the comments of many users, can occur for various reasons. Often this value is shown on the display during mechanical shocks to the car, as well as in the event of excessive fuel consumption associated with engine breakdowns. Despite the prevalence of this problem, if the treasured numbers are discovered, it is necessary to contact specialists who will conduct a full diagnosis and identify faults.

Indicator “low efficiency of catalysts”

If the numbers P0420 appear, these are error codes indicating insufficient efficiency of the catalyst system.

If the problems are not corrected in a timely manner, you will have to spend considerable effort and money on restoring the Toyota Camry automobile unit.

It’s bad if the resource is exhausted, but the problem can be solved: contact a specialized service, where you (or rather, your car) will be helped and assisted in finding problems.

Error 1604

This situation (referred to as P1604) indicates the presence of several (or one) unsuccessful attempts to start the car engine. The solution to the problem depends on the reason why the launch failed. If this is an incorrect start or mechanical action, it is worth trying again; if it is frosty or cold, reheat the unit. If the reason is unclear, only a qualified technician can provide proper assistance in solving this problem. The erroneous parameter P1604 is common, but this does not mean that it can be ignored.

Error value A799

This parameter can be deciphered in different ways, depending on the nature of the malfunction. This may indicate a malfunction of several elements or exceeding the course speed. Errors 799 are less common than other faults, but nevertheless they do occur. The first action that the driver must take is to understand the cause of the problem in order to ensure the stability of all vehicle systems. A competent approach to solving the problem will ensure your peace of mind and constant comfort.

Description of the self-diagnosis process

First you need to check that the battery has a voltage of at least 11 volts, the throttle valve is closed, and all electrical appliances are turned off. For convenience, you also need to prepare a homemade jumper from a metal clip or wire.

• turn off the ignition;
• using a paper clip, close the 4th and 13th contacts on the OBD-II connector;
• turn the key to “ON” mode (do not start the engine);
• after 4 seconds, read the ABS error code;
• remove the jumper clip from the installed contacts.

The error is indicated by two numbers: the first is counted by the number of blinking indicator lights every 0.5 seconds, then a break, the second is also counted by the number of blinks with an interval of 0.5 seconds. After 2.5 seconds, the next code is issued, etc. When all codes have been issued, after a break of 4.5 seconds, the codes are issued again. If there are no errors, the interval between signals is 0.25 seconds.

Two-digit ABS codes are deciphered using special tables.

Modern scanners

There are now many scanners available for reading car error codes that completely decipher error codes. These programs are translated into Russian, are easy to use and allow you to configure vehicle parameters. For example, the time when the headlights go out after turning off the ignition, after how many seconds the lights in the cabin go out when boarding, disembarking, and more.

The car owner should think about purchasing diagnostic equipment. Not bad manufacturers of diagnostic devices: Launch, ELM, Autel, Autocom, Carman.

How to turn off the ABS lamp

Next, you need to eliminate the identified faults. To stop the warning light from flashing, it is not enough to eliminate the fault. To turn it off, do the following:

1. Start the engine and drive for half a minute at a speed of 20 km/h.
2. Make sure the ABS light is not flashing.
3. Reset error code.

If this does not help, the lamp continues to blink, there is a second option:

• Stop the car for 5 - 7 seconds.
• Press the brake pedal several times.
• Continue driving at a speed of 50 km/h.
• Depress the brake pedal for three seconds.
• Repeat three times.

After the ABS light goes out, you need to reset the error code.

Reset errors

After the repair has been made and the breakdown has been fixed, the error codes may not disappear on their own. There is also a certain sequence of actions to reset them. To do this, we again need a diagnostic connector.

To reset codes you need to:

1. Turn on the ignition.
2. At the DLC1 connector, short-circuit the TC and E1 terminals with a piece of wire or wire.
3. In 3 seconds, press the brake as many times as possible, but not less than 8.
4. Make sure the light blinks evenly at half-second intervals.
5. Turn off the ignition and remove the jumper from the contacts.
6. Make sure that the ABS indicator does not light up.

“Artem0023” explains in the video how to carry out self-diagnosis of Toyota cars step by step:

6.2.2. Self-diagnosis (OBD) system and codes

Digital voltmeter

Warning

On models from 1990 to 1994, the OBD1 self-diagnosis system is installed, and since 1995, the OBD2 self-diagnosis system is installed.

To determine fault codes in the OBD1 system, you simply need to disconnect the test connector located under the instrument panel. But to determine fault codes in the OBD2 system, you must use a special device to view fault codes. To diagnose the exhaust gas emission reduction system and control engine operation, it is advisable to use a digital voltmeter, which has a high input resistance and does not affect the operation of the circuit being tested (see Fig. Digital voltmeter ).

To determine fault codes and analyze engine control systems, it is necessary to use special scanners (see fig. Scanner ).

The ECM contains a built-in self-diagnosis system that detects and classifies faults in electrical circuits. When the ECM detects a malfunction, the check engine light comes on, the malfunction is identified, and a fault code is written and stored in memory.

There are four methods for self-diagnosis of engine malfunction. The check engine light comes on if there is a fault in the U-mode.

Toyota Error Codes

Toyota error codes are encrypted information about existing malfunctions in the operation of the engine and its systems or automatic transmission. Modern models are equipped with electronic control modules with self-diagnosis systems. They are designed to optimize the operation of equipment, reducing fuel consumption and minimizing the toxicity of exhaust gases.

You can read and decipher Toyota errors at the specialized Toyota Dubrovka car service center. Our diagnosticians have been certified by the manufacturer and work according to its regulations; they will carry out the appropriate measures and provide all the necessary information to the car owner in a printout.

Toyota error codes: how are they read?

In order for the Toyota electronic control module to be able to receive the necessary data from the systems it controls, they are all equipped with sensors.

If deviations from the norm established by the manufacturer in the sensor readings are detected, an emergency mode is launched, accompanied by a corresponding indication on the dashboard.

If the normal operating parameters of the sensor are restored (after repair, replacement or independently), the standard operating mode and the engine or automatic transmission return. At the same time, data that malfunctions have been identified are recorded in the database in the form of Toyota codes and remain there.

Toyota malfunctions can manifest themselves in different ways: it happens that the engine stalls, attracting the attention of the driver who seeks auto repair help, and it also happens that the engine at first glance works well and its failures are not visible, although the corresponding warning light is lit on the dashboard indication.

The latter often causes serious breakdowns, the elimination of the consequences of which requires significant investment. In this regard, Toyota's OBD2 error code system is very convenient. It detects even random failures in the operation of units and provides information about them during diagnostics.

Thanks to this, the owner has the opportunity to take measures to prevent serious malfunctions or breakdowns of the car on the road.

Toyota Camry error 40: fault codes, how to reset

HomeCamry Camry error codes help, using computer diagnostics, to make the correct “diagnosis”, to understand which element, motor sensor, gearbox, etc. has failed. This significantly speeds up car repairs. Modern scanners independently decipher error codes, but if you use diagnostic equipment that does not do this, we will try to help.

The inscription on the computer screen is CHECK VSC SYSTEM.

Automatic transmission fault codes, possible faults

Automatic transmission repair is one of the most complex car system repairs. High-quality maintenance and repair of an automatic gearbox is impossible without computer diagnostics. It should be noted that diagnostics allows you to determine mainly errors in sensors, solenoids (solenoid valves), and control circuits.

As is the case with engine management system components, you should not immediately start replacing, for example, an automatic transmission solenoid. It is necessary to gain access to it (sometimes after removing the automatic transmission and disassembling it), then measure its electrical resistance. For most solenoids, the resistance value is in the range from 10 to 25 ohms.

You cannot replace solenoids without cleaning the chips and changing the oil in the automatic transmission. If the automatic transmission is more than 10 years old, you can simultaneously perform routine maintenance using the appropriate overroll kit. Computer diagnostics do not report mechanical faults of components in the form of codes.

Proper diagnostic work on Camry 50

Diagnostic connector in Camry 30 The sequence for reading the error code is approximately the same for all Toyota cars:

• with the ignition off, connect the scanner to the diagnostic connector,
• establish a connection between the scanner and the phone via Bluetooth, if the diagnostic program is installed as an application on the smartphone; connect the scanner to a laptop computer on which the diagnostic program is installed,
• in the program menu to read the error code, select the Toyota Camry of the required year and body,
• turn on the ignition or start the engine and start scanning,
• the program will display error codes that have been stored in the vehicle control units since the last time the fault codes were deleted,
• delete all errors, drive the car for 2-3 kilometers and read again, now the equipment will show only existing problems, and not all, including those that have been resolved,
• write down the error codes, if the program decrypts, then write down or save the problems shown,
• After completing diagnostic operations, turn off the scanner and ignition.

After the manipulations have been performed, analyze the information received and troubleshoot.

How to perform computer diagnostics on Camry 40

Various scanners are used to diagnose blocks and components of Toyota Camry v40 cars. Optimal scanning is performed using dealer devices. You can use universal professional and semi-professional diagnostic devices. Engine diagnostics can be performed using simple scanners such as ELM327.

In this case, some specific errors in the engine management system may not be detected. Common errors in the OBDII protocol will be fully identified. In most cases, this is enough to identify most faults.

The sequence of diagnostic work is approximately the same for all devices:

1. Turn off the ignition.
2. Connect the vehicle diagnostic connector to the scanner.
3. Connect the scanner to a computer (if it is not a single unit) or to a smartphone, as in ELM
4. If using a Bluetooth connection, make it using a smartphone.
5. Download the diagnostic program to your computer (with the exception of integrated Launch scanners). Select the car model, year of manufacture, scan type.
6. Turn on the car ignition and wait until the on-board computer performs self-diagnosis.
7. Start scanning.
8. As a result of scanning, the program will display error codes that have accumulated in the scanned control units.
9. Write down all error codes. Some programs automatically decipher error codes, sometimes in Russian. In this case, the transcript must also be recorded. Sometimes some errors are not decrypted by the diagnostic program. This can be done later using search engines or on forums.
10. Remove all errors. Perform diagnostics again. After completing these steps, only valid errors will remain. Data about previously recorded errors will be erased; perhaps some sensor was disconnected and then connected again. Some of the inactive errors may appear again after several kilometers of driving the vehicle.
11. Record valid errors.
12. During professional diagnostics, the next stage is a dynamic scan, as a result of which it is possible to determine: ignition timing, instantaneous fuel consumption, temperature conditions, and other important parameters of engine operation. To perform dynamic diagnostics, the engine must be started.
13. All units of the car are scanned in the same way: the brake system, automatic transmission, climate control, immobilizer, body control unit and others.
14. At the end of the diagnostic work, the ignition is turned off and the scanner is disconnected from the diagnostic connector.

Next, we begin to analyze the errors and their arrangement.

Engine error codes, possible malfunction

After performing diagnostic work, it is necessary to obtain as much information as possible about the suspected malfunction. For example, computer diagnostics showed error P0032.

According to the table below, it is interpreted as exceeding the maximum current in the heater circuit of the first lambda probe.

You should not immediately buy a new sensor (in Camry it costs more than 3,000 rubles).

First of all, you need to check the electrical wiring that leads to it. The Camry, like most new gasoline cars, has two oxygen sensors (lambda probes) - one before and one after the catalyst.

They are heated, that is, there is a spiral that heats the sensor to enter working condition. It is possible that the sensor is faulty, the coil is shorted, and the diagnostics shows error 0032. But in most cases, the cause of this malfunction is a short circuit in the wiring leading to the lambda probe.

It is laid in close proximity to the exhaust manifold, which heats up to a temperature of more than 300 degrees Celsius. If the PVC insulation is destroyed, the wiring may have a short to ground on the vehicle. In this case, error P0032 may appear.

It is possible that the error will disappear at the time of diagnosis, but then it will appear again while driving, so it is better to check the quality of the insulation.

Below is a breakdown of the main engine error codes and their possible causes.

If the automatic transmission is more than 10 years old, you can simultaneously perform routine maintenance using the appropriate overroll kit. Computer diagnostics do not report mechanical faults of components in the form of codes.

ABS fault codes, possible faults

ABS system error codes make repairs much easier. If the anti-lock brake system malfunction indicator light comes on, it means that it has become completely inoperable. Continuing to drive, especially on slippery roads, is dangerous.

Modern scanners

There are now many scanners available for reading car error codes that completely decipher error codes. These programs are translated into Russian, are easy to use and allow you to configure vehicle parameters. For example, the time when the headlights go out after turning off the ignition, after how many seconds the lights in the cabin go out when boarding, disembarking, and more.

Toyota Camry 40 error codes

Check VSC System - a message appears on the on-board computer screen.

The Check VSC System notification itself does not carry specific information; it is a warning that something is wrong with the car. There may not be any significant problems, for example, if you refuel with the engine running, or you have recharged a dead battery, Check VSC System will appear. If there is no breakdown, the message will go away, turn off and start the car 10 times or disconnect the terminal from the battery for 5 minutes. The notification does not go away, then carry out computer diagnostics of the Camry.

The inscription on the computer screen is CHECK VSC SYSTEM.

Deciphering Toyota Camry fault codes

When performing self-diagnosis of the car, errors are displayed on the instrument panel. Depending on the year and equipment of the car, information is transmitted in two ways.

1. Using a special indicator blinking. This kind of “Morse code” has a certain decoding, but is unloved by motorists.
2. Digital code on the tidy display. This is usually a two-digit number or a code with letters added. A detailed description of common breakdowns is given below.

C1AED - Toyota error

Data exchange between the parking sensors unit and the rear sensors is disrupted. It is necessary to check the sensors for functionality.

C1AEC - Camry error

Found with cars in the 50 body. The problem is similar to the one above, only with the front of the car. Sensitive sensors often suffer from small stones and road debris.

U0100 - Camry error

Loss of communication with the power plant control unit. The module works properly and is difficult to damage. In 80% of cases, the problem is in oxidized terminals or broken wiring.

Error U0101

On the assembly of SV40 and others, it means that the DPKV is not working correctly. It is easier to check the malfunction by connecting a known functioning device.

Error 21

On 2AZ FE engines, the reason is hidden in the oxygen sensor before the converter. The most common cause here is wiring. The sensor is located in a place exposed to dirt and road reagents.

Fault 23: Camry 30

The solenoid valve of one of the wheels of the ABS system is damaged. The causes and solutions to the problem are the same as above.

Code 24: Camry SV30

One of two possible malfunctions is present:

• intake air temperature sensor;
• ABS sensor.

Fault 42: Camry Grace

The vehicle speed sensor is not working correctly. The speedometer needle may fall or “take on a life of its own.”

Camry 70 errors

The data transmission system did not determine the source of the failure. More detailed diagnostics are required.

Camry code 40: C0210

The rear right ABS sensor has failed. The problem indicates a tire puncture or insufficient air pressure in it - the tire rotates faster than the rest.

C1201 - error

ECM malfunction. You will not be able to fix the problem on your own. Seek qualified help from specialists.

P0012: Camry V40 - error

Camshaft timing is incorrect. A malfunction occurs due to the presence of debris or foreign particles in the area where the sensors operate.

Error P0171

Excessively lean fuel mixture. An adjustment needs to be made.

P0172 - code

DK1 shows an excessive amount of fuel residue in the exhaust system. There is a malfunction or incorrect setting of the mixture formation system. Check the injector and pressure lines.

P0351 - code

In parallel with the appearance of the error, the car’s power plant may lose power. Look for a problem on the car's ignition coil.

Code P0335

The crankshaft position sensor A circuit is faulty. Check the wires for damage or oxidation of the contact groups.

P1604 - error V50

Failure to start the power plant. A more thorough diagnosis is required.

Error P1660

The intake manifold geometry change drive is not working correctly or the sensor is transmitting incorrect data. Check the system for dirt or carbon deposits.

P2109 - error

The throttle valve is not functioning properly. Usually the problem is simple dirt stuck to the internal parts of the device.

P2238 code

Low signal level of the positive circuit of the oxygen sensor. There may be two problems here.

1. Problems with the settings of on-board systems.
2. Problems with the sensor or its wiring.

P2716 - error

The code indicates an electrical problem with the oil pressure control valve inside the automatic transmission. Check wiring components for damage.

P2714 - error

The PCM system produces a similar signal when the pressure control valve D is faulty or stuck in the off position. Fires at the same time as code U660E.

To perform repairs, clean the mechanical part of the sensor or completely replace it.

Camry Error V40: Check VSC System

The problem occurs on cars with diesel power plants. Check the fuel system for damage. It may also turn out that the tank is filled with low-quality fuel or with foreign impurities.

Climate control errors

Older versions of the car are not subject to installation problems. With the complication of the design of the unit and the integration of an advanced air conditioner, the shortcomings of the module began to appear.

If there are problems, it is recommended to show the car to specialists.

Camry charging system malfunction 55 error

Charging failure is accompanied by the appearance of a battery-shaped light on the dashboard. If it is not possible to perform thorough computer diagnostics, it is recommended to check the following areas:

• generator wiring;
• voltage regulator;
• serviceability of the battery itself.

Automatic transmission errors

If the machine breaks down, do not try to fix the situation yourself. An automatic transmission is a complex mechanism consisting of many components. It is not recommended to get into the module without knowledge of the device and the principle of repair.

Error: Check Sonar

There are problems with the parking sensors system. The device should be thoroughly diagnosed or sensitive parts of the sensor should be replaced.

ABS errors

Installed on cars since 1996. The module reports faults related to sensors or their wiring. The sensors are installed in places exposed to dirt and road chemicals.

P0351, P0352, P0353, P0354, P0355, P0356

Ignition coil errors, the last two can only appear on Toyota V6 engines, for example, 2GR-FE. Reasons for these codes:

• faulty ignition coil,
• faulty wiring leading to the coils,
• broken electronic control unit.

To accurately determine the malfunction, use an oscilloscope to measure the electrical signal from the ignition coil that showed the error. If you don't have an oscilloscope, you can swap the potentially faulty coil with another. For example, there is an error P0351, we moved the coil from the first cylinder to the second, now the scanner shows P0352 - the problem is in the coil, but if the code remains the same P0351 - the wiring or ECU is faulty.

Airbag fault codes

If there is a message on the dashboard about a malfunction of the airbag system, you should definitely check which elements and sensors are faulty or there is no communication with them. The resistance of the airbag and belt pretensioner squib can be checked with a multimeter, it is about 2 ohms. Error codes with explanations are given in the table.

P0172

Error P0172 - Air/fuel mixture too rich. Causes:

• air intake system,
• faulty injectors,
• not working correctly mass air flow sensor,
• fuel pressure is outside acceptable limits,
• exhaust gas leak,
• the problem is in the circuit or in the oxygen sensor itself,
• ECU.

To make an accurate diagnosis, contact an experienced specialist. One option to eliminate the error is to replace the VVT-I valve.

P2237

P2237 – open circuit in the oxygen sensor (A/F) pumping current circuit, P2238 – low current in the oxygen sensor (A/F) pumping current circuit (1 row 1). We are talking about a lambda probe installed before the catalyst, which is located next to the engine. This error may not affect the behavior of the car, but fuel consumption will increase. We would like to warn against replacing this sensor with a non-original one.

The lambda probe, located before the catalyst near the engine, is replaced only with the original one. The second sensor installed after the catalytic converter can be replaced with a universal one. Using this head will allow you not to remove the heat shield when replacing failed lambda probes.

Engine error codes, possible malfunction

After performing diagnostic work, it is necessary to obtain as much information as possible about the suspected malfunction. For example, computer diagnostics showed error P0032. According to the table below, it is interpreted as exceeding the maximum current in the heater circuit of the first lambda probe.

It is possible that the error will disappear at the time of diagnosis, but then it will appear again while driving, so it is better to check the quality of the insulation.

Below is a breakdown of the main engine error codes and their possible causes.

P0137, P0157

P0137, P0157 – low voltage in the oxygen sensor circuit (bank 1, bank 2 sensor 2). Causes of errors P0137, P0157:

• open circuit, break in the heated oxygen sensor circuit, row 1,2 sensor 2,
• faulty lambda probe (heated oxygen sensor),
• air/fuel mixture sensor bank 1,2 sensor 1,
• leakage from the exhaust gas system.

New and Old Lambda Sensor If, during active air-fuel ratio control, the target ratio is rich but the heated oxygen sensor output voltage is less than 0.21 V (lean), the ECM treats this as an excessively low sensor output voltage and sets DTC P0137 or P0157 . During active air-fuel ratio control, if the target ratio is lean but the output voltage is greater than 0.59 V (rich), the ECM considers this to be an excessively high sensor output voltage and sets DTC P0138 or P0158.

If replacing the sensor did not bring results, then the technicians could have replaced the wrong sensor (this happens often), or the problem is not in the sensor, but in the circuit or in an exhaust gas leak. Check all connectors; they may have oxidized or moisture may have gotten into them. Visually inspect the wiring to see if its integrity is damaged. If the circuit is visually in order, then check its operation using an oscilloscope.

Checking the airbag system indicator Set the ignition switch to the “ACC” or “ON” position, check that the warning light comes on and goes off after about 6 seconds. Note: If the ignition switch is in the “ACC” or “ON” position and the indicator remains on or flashes, check the fault code. If the indicator sometimes lights up or remains on even when the ignition switch is in the “OFF” position, check the indicator circuit for a short circuit .

Mechanism to prevent activation of the SRS system.

1. Set the ignition switch to the “ACC” or “ON” position and wait approximately 20 seconds. 2.

Install a jumper on terminals “TC” and “E” of the diagnostic connector. Note: Incorrect pin connections may result in system failure.

3, If there is no fault, the indicator will flash 2 times per second.

4. If there is a malfunction, the indicator will flash at a variable frequency. Identify trouble codes.

. The figure shows an example of the output of codes “11” and “31”.

5. Fault codes are displayed from the smallest. If codes are not output, check the “TC” output circuit of the diagnostic connector.

As an example, the figure below shows the flashing patterns of the ABS and VSC warning lamps (for models without a multi-information display) for the system normal code and fault codes 11 and 21, as well as the display of trouble code 32 for VSC on the multi-information display (for models with a multi-information display ).

5:2589

Note: Look at all lights. For example, if there are errors in the ABS system, then this lamp will show the error code. The on-board computer can also report diagnostic results (for example, “DIAG VSC 21” or “VSC DIAG OK” if there are no errors). There are cases when the codes read from the light bulbs do not match those issued by the on-board computer. This situation can occur when there are problems with the “brains” (ECM/PCM/ECU). 5. Turn the ignition OFF. 6. Remove the jumper from pins “4” and “13”. Resetting codes: 1. Turn the ignition OFF. 2. Bridge contacts “4” and “13” (with a paper clip, wire, wire). 3. Turn the key to the “ON” position, but do not start the engine! 4. Press the brake pedal 8 or more times in an interval of ~3 seconds. 5. The indicator that generated the error should display a normal code (the interval between flashes will be ~0.25 seconds). There may still be errors that are currently malfunctioning. 6. Turn the ignition OFF. 7. Remove the jumper from pins “4” and “13”.

Codes 21 and 24 can pop up if diagnostics are carried out in a dark room or at night. Due to loss of connection with the instrument panel, code 71 cannot be displayed on it.

What is “compressor blocking”? Many people do not understand this point. The principle of correct operation is simple. When the compressor is OFF, the accessory drive belt rotates only the accessory drive belt pulley. If the compressor needs to be turned ON, the electromagnetic clutch is activated (the compressor is locked with the pulley and begins to rotate). The brain receives a signal from a sensor (similar to the ABS sensor) that the compressor is turned on and rotating. This sensor then transmits pulses to the ECM equal to the engine speed. If the ratio between the compressor and engine speeds deviates by 20% or more from normal operation, the ECM turns off the air conditioning compressor and the indicator begins to flash with a period of ~1 s. Data on the operating status of the compressor is transmitted by the ECM to the air conditioning control unit via a multiplex data transmission system (CAN and BEAN buses).
