Toyota Avensis climate control error codes

Climate control is a useful addition to any modern car. It serves to maintain optimal temperature in winter and summer. The advantage of climate control over a conventional air conditioner is its almost complete autonomy. Car owners have to pay minimal attention to the interior cooling and heating system, concentrating on driving the car. It is imperative to periodically check the level and quality of the coolant.

If freon and oil leak out, this will require financial costs that cannot be called small. The reasons for system failure vary. Self-diagnosis of climate control allows you to determine the malfunction without the intervention of specialists and unnecessary expenses and try to solve the problem yourself.

Decoding error codes on Toyota cars

Technical defects appear sooner or later in cars of all manufacturers, including Japanese ones. The driver can decipher Toyota error codes independently, and it is possible to determine system malfunctions without the use of scanners. If a car enthusiast has never encountered such a problem before, then this article will help you understand all the nuances and perform the work at a professional level.

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.

Toyota car diagnostics

Diagnostics are available on cars of the entire Toyota model range and are divided into two types:

Before starting electronic diagnostics, the driver must ensure that all systems and main mechanisms of the Toyota vehicle are in working order. To do this, you should check the fuses, electrical wiring, and also examine the connections and components of the vehicle for damage.

If any serious problem is detected, it must be eliminated, and only then carry out computer diagnostics, which can happen:

Step-by-step self-diagnosis

For self-diagnosis, the driver needs to work with the DLC 1 and DLC 2 connectors. This abbreviation stands for Data Link Connector, which in English means a connector for connecting data. DLC 1 looks like a plastic box with a lid on top. It is located under the hood, most often on the left. It is easy to find by the inscription Diagnostic.

Diagnostic signature on the connector

In older models, the diagnostic connector is shaped like a yellow circle and is located near the battery. There are no DLC2 parts in cars like the Corolla AE 100.

Fault codes for older car models: Toyota Corona 1992, Karina 1992-97, Toyota Mark are read only by flashing indicators.

In new models, DLC 2 is located directly in the cabin, under the dashboard and “at the feet” near the steering wheel. Most often it is round and is used during inspections carried out using special equipment.

Round DLC2 connector

When performing self-diagnosis by shorting individual contacts of the connector, only by connecting them in the required sequence can you obtain the correct code for decoding.

The following steps will help you find out if there are faults in the engine and/or gearbox system:

Everything is fine with the car and no damage to the internal combustion engine or transmission was detected if:

Any other combinations of light bulbs indicate a malfunction in the engine systems, gearbox or other mechanisms in the car.

If the circuit on the back of the cover has been erased, you cannot find the contact or you are not sure that you have closed the right one, you must:

It will be more convenient if someone helps you monitor the light bulb while you change the position of the wire.

Recognize fault codes using two flashing light systems.

The first setting option will allow you to find out errors indicated by a two-digit code (type 09):

Using the 10th setting type, unambiguous codes are determined. Here the light “blinks” the exact error number.

This code should be “read” according to the following rules:

The video shows diagnostics using type 9 code, author Dmitry Kuzmin:

Failures in the ABS system are determined using the same scheme, but the TC and E1 terminals are closed. The SRS and 4WS fault codes are read by the corresponding sensor with the same contacts closed as in the ABS.

What does "Prado" mean?

In order to understand what Land Cruiser Prado means, it is better to look at each word separately. “Land” translated from German means “edge”, “country”. The English language interprets this definition more broadly: “world”, “continent”, “land”.

The concept of “cruiser” is interpreted approximately the same in most world languages. In France it is a “yacht”, in Italy it is a “ship”, in English it is a “cruiser”, and often a “space shuttle”. Sometimes "cruiser" means "traveler".

Attention! The word "Prado" has a deeper meaning and refers to the Spanish language. In the Castilian dialect it means “park”, “field”, “lawn”. This word also means “a place where festivals are held.” The word “Prado” can also be associated with Prada clothing, the production of which also originates in Spain.

Thus, the car can be described as “a traveling cruiser in a clearing.” However, given the variety of interpretations of each word, anyone can combine them into one phrase, limited only by their imagination. In this case, all names will be relatively correct.

Troubleshooting

Type 9 error codes common to all Toyota vehicles are represented by two-digit codes.

The general list of unambiguous codes (type 10) for a Toyota car consists of the following items.

Gasoline internal combustion engines

If the car has an on-board computer or robot, the code will appear on the mileage screen. It will consist of a Latin letter at the beginning, for example P, B, C, and 4 numbers. This is typical for cars such as Toyota Rav 4 Avensis, Corolla, Mark II or Land Cruiser 200, Toyota Prado 120 and others that run on gasoline.

Table for deciphering diagnostic fault codes for gasoline internal combustion engines.

Diesel engines

Many Toyota cars were produced with a diesel engine. The most popular models are the Vitz, Caldina, Avensis (T25), Camry, Camry Grazia, Corolla E150, Auris 2008 sedans, Land Cruiser Prado 120 and Land Cruiser Prado 200 SUVs or the RAV4 crossover.

When writing down codes for diesel cars, you can see the following symbols.

Failure of other diesel engine parts.

Automatic transmission

Cars of the same brand differ not only in the engine, but also in the gearbox. For the same Toyota Corolla 150, Celsior or Vista, automatic transmission failures will differ from mechanical failures.

If there is a malfunction in the transmission, you will see one of the codes.

Such errors are typical for different models, including Toyota Ipsum, Toyota Highlander 2001 and Caldina.

Other combinations

Special equipment and devices are also used for diagnostics. Such devices will show five-digit codes. They can also be recognized using the on-board computer, which is installed in new cars and hybrid models.

Code on the Toyota screen with on-board computer

Toyota Estima, Toyota Prius, third generation Toyota Harrier and others came out in the hybrid version. These models (in addition to other breakdowns) may experience malfunctions of the high-voltage battery system (HVB). Hybrid installation error codes and their interpretations are given in the table.

The most common non-VVB error codes are:

Weaknesses of the 4th generation Toyota Land Cruiser Prado

Exaggeratedly, all the shortcomings of this model can be represented by the following list:

Now let's look at some of them in more detail...

It can hardly be said that these parts fail very quickly and require constant replacement, but every 60 thousand kilometers they require cleaning. Since injectors for this machine are quite expensive, basic preventive maintenance will not be superfluous, especially if you take into account the quality of domestic fuel.

By 150 thousand mileage, this model has problems with coolant leaks from the radiator, pipes and pump. Due to the design features of the machine, you are unlikely to be able to carry out repairs yourself, so you will have to contact a service station. Depending on the service you choose, the cost of repairs will cost you about 20 thousand rubles.

In certain versions of the Toyota Prado 150, the transfer case actuator is considered a sore spot. This component often fails during frequent off-road driving in aggressive conditions. If the vehicle is operated in urban conditions and very carefully, then this will not be a problem. But if, when you turn on the lock, you feel a slight jolt and extraneous noise, this is a good reason to bargain with the seller.

Around 100 thousand kilometers, a malfunction of the body position sensor often appears. Of course, the problem is not global, but it must be eliminated. This “jamb” manifests itself in the fact that the machine is always in the highest position. Replacing this element will cost the owner approximately 20 thousand.

Many people note the low quality of painting as a problem for this “Japanese”. For some owners, even after several months of starting to use the car, the paint on the hood and top of the roof begins to peel off and crack. That is why, when purchasing this car, pay attention to the condition of these body elements.

In some cases, after driving more than 100 thousand kilometers, the starter may need to be replaced. This problem does not apply to all cars of this model and the nature of its occurrence is still unclear. But the fact remains that for some owners, for no apparent reason, this unit fails. Moreover, this happens selectively and does not depend on the year of manufacture.

With aggressive and frequent off-road driving, pneumatic cylinders and the compressor may not withstand the loads and fail. Symptoms of an impending breakdown include raising the car to its maximum height for a long time, and also if the car sits motionless for a long time with the engine turned off, the ground clearance will decrease for no apparent reason. Replacing or repairing air suspension is a very expensive proposition, so when purchasing a car on the secondary market, have it fully diagnosed at a certified service station.

In general, the rubber products used on this machine have proven to be of high quality. However, this does not apply to the seals in the gearbox. At mileage of 100 thousand or more, oil leakage from under this seal is often observed. The cost of resolving the issue is not very high, but the very fact of the presence of such a malfunction spoils the overall impression of the car.

What are other disadvantages of this model?

With aggressive driving and after driving more than 100 thousand kilometers, it may also be necessary to replace ball joints, stabilizer rods and bushings, CV joint boots, steering rack, and so on. However, it is worth understanding that all this does not happen at the same time, thereby giving Prado owners the opportunity to wisely allocate cash investments for the repair and maintenance of their vehicle.

Why is Prado better than Pajero?

In the next step, for an expanded selection, you can enter the vehicle's Vin code to go to illustrated catalogs, where you can find the layout of parts down to the bolt and duplicates that are not in the catalog of analogues.

See also other spare parts

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:

Most of the diseases inherent in the previous model have been eliminated in the new generation. However, in place of the previous problems, new ones have appeared that spoil the first impression of the car, but do not force us to categorically refuse to buy this SUV.

1. The first thing you will be disappointed with almost immediately after purchasing a Prado is its sound insulation. From a car of this class, many expect better insulation of the interior from aerodynamic noise, engine noise and other extraneous sounds.

2. Sometimes there is slurred operation of the five-speed automatic transmission. Sometimes the automatic transmission “thinks” for a very long time before switching to fifth gear, spinning the engine up to 3500 rpm, and it also happens that at a speed of 100-110 km/h it suddenly switches to a lower gear and then starts switching “up” and “down”. In the first case, switching to manual mode and independently turning on the fifth speed will help, and in the second, you can use the throttle control.

3. The 3.0-liter turbodiesel four-cylinder engine has a very noticeable “turbo lag” that is not immediately felt. The turbine itself turns on at 1200 rpm.

4. Due to poor thermal insulation, the car’s power unit cools down quite quickly, which again is more pronounced on the diesel version. It will take a little more than 10 minutes for a diesel engine to cool completely even in slight frost. It is worth noting that in severe frosts the temperature may drop even at idle, so it makes sense to invest in installing thermal insulation material.

5. Turbodiesel injectors do not last as long as those on gasoline engines, which is due to the quality of our diesel fuel. They will have to be cleaned periodically, and after a mileage of about 150,000 kilometers they may even need to be replaced, which will seriously lighten your pocket.

6. Being a full-fledged frame SUV, the Toyota Land Cruiser Prado demonstrates excellent driving performance on moderate off-road conditions, while on asphalt it may not seem very soft. In this regard, the equipment with air suspension, the maintenance of which is an expensive pleasure, will be much better.

7. The salon, although at first glance seems expensive and luxurious, is decorated with materials that are far from being of the highest quality. That’s why you can often hear about the appearance of “crickets,” especially on the right side of the windshield, even on cars that are less than a year old.

9. Rare electrical problems occur. Some complain about the power windows, some have parking sensors beeping for no reason, and some are bothered by electronic “assistants”, of which there are quite a few in the new Prado.

Software shutdown and mechanical removal of the EGR system and particulate filter is one of the important areas of work of the Muffler Service. Today the technicians are working on a Toyota Prado, disabling the Land Cruiser EGR system and removing the particulate filter.

The Land Cruiser Prado SUV has been popular for more than two decades. This Toyota model has won the hearts of car enthusiasts with its interior comfort typical of passenger cars, excellent cross-country ability and excellent Japanese quality.

Today the experts will work on a representative of the 2012 Toyota Prado - the owner of a 3-liter engine with 173 horsepower and a torque of 410 Nm. The car started to start “every time”; there was a constant error on the panel... The owner turned to us for help. The problem is clear - the Land Cruiser particulate filter is clogged. It was decided to disable the EGR system of the LC Prado 150 and remove the particulate filter.

Technically, we always start the procedure with the software part (reflashing the Toyota Prado ECU), and the physical removal of the Toyota EGR system is done when the “heart” of the Land Cruiser has already been reprogrammed.

We will reflash the Toyota Prado engine and disable the EGR using a programmer that can provide high-quality and reliable results for the Land Cruiser. The work will be carried out without disassembling the Land Cruiser Prado 150 control unit - we will connect to the ECU through a special port for Toyota diagnostics. It is located above the gas pedal.

Let's continue with the physical removal of the particulate filter. The craftsmen install all the necessary plugs.

The result is that the errors on the LC Prado 150 panel have disappeared, the engine starts perfectly right away. It takes about 4 hours to work with Toyota. The client also purchased an Autoheat thermal blanket for his Land Cruiser. In cold winter, this is an indispensable assistant, retaining the heat of the Toyota engine for up to 6 hours, helping to significantly reduce the number of idle starts on the Land Cruiser, providing good noise insulation and fuel economy.

The owner of the Prado decided for now to stop at disabling and removing the EGR system (USR), but we can also do chip tuning for the Toyota Land Cruiser. And, as we have already noted, purchase spare parts and receive quality service.

The fourth generation Toyota Land Cruiser Prado, 150 series, was introduced in the fall of 2009. The J150 has undergone two restylings - in 2013 and in 2021.

The body-on-frame mid-size SUV is based on the modernized platform of its predecessor, the Prado 120 series. The Land Cruiser Prado 120 was famous for its legendary endurance and reliability. How are things going with this for the receiver?

Although I didn’t notice any confusion in the operation of the climate control, I’ll look into it.

And so, in order to enter the climate control self-diagnosis mode and identify error codes on Toyota, you need to do the following:

In the ignition switch, turn the key to “ON”; Turn on the stove and air conditioner; Then turn the key to the “ACC” position; We simultaneously press two buttons - air recirculation and “AUTO”; Turn the ignition back to the “ON” position; The indicators on the display will blink (should light up 4 times with an interval of 1 second); After which diagnostic codes will begin to be displayed. To exit the climate control error checking mode, press the “OFF” key. And if you need to clear the climate fault memory, then while diagnosing the sensors, simultaneously press the front and rear window heating buttons.

Japanese cars are distinguished not only by increased reliability, but also by comfort. And one of the proofs of this is the climate control in the Camry , which automatically provides a comfortable temperature for the driver and passengers. The basis of a car’s climate system is a control unit, which also controls the temperature and direction of airflow. But it does not last forever, and may fail during operation.

Features of self-diagnosis of climate control in cars

If freon and oil leak out, this will require financial costs that cannot be called small. The reasons for system failure vary. Self-diagnosis of climate control allows you to determine the malfunction without the intervention of specialists and unnecessary expenses and try to solve the problem yourself.

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:

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:

Toyota climate control error codes

I don’t know, maybe someone has already written about climate control self-diagnosis, but I still decided to create a topic. Today I came across a message on one of the forums I read about self-diagnosis of the climate control of Toyota cars. I read it, checked whether it works, yes everything works and displays errors as promised. In my case, it showed error number 11 - Interior air temperature sensor.

Although I didn’t notice any confusion in the operation of the climate control, I’ll look into it.

Although I didn’t notice any confusion in the operation of the climate control, I’ll look into it.

I don’t know, maybe someone has already written about this, but I decided to make a post for myself and of course for you.

And so, the sequence of actions:

A little about compressor blocking

Blocking the compressor does not mean that it is jammed as a result of foreign objects getting inside.

Compressor blocking

The fact is that when the electromagnetic clutch is turned off, only the pulley rotates with the drive belt. And after pressing the AC key on the climate control unit, its signal activates the electromagnetic clutch, connecting the pulley and the rest of the compressor mechanism. Its rotation frequency is controlled by a special sensor, which transmits signals to the ECU. If a discrepancy between the compressor rotation speed and the engine speed is detected by more than 20%, the climate control unit will automatically turn off the electromagnetic clutch, thereby stopping the compressor. In this case, the AC indicator light on the climate panel will begin to flash once per second.

Therefore, if, when you turn on the air conditioner, warm air blows from the air ducts, and the climate control on the Toyota Camry 40 shows an AC error, then the first thing you should do is check the condition of the belt and its tension.

Error manifestation and engine “behavior”

If there is something wrong with the TPS sensor, the ECM will receive incorrect throttle position data or no throttle position data at all. The electronic control unit will be “misled” by this and, at best, will begin to control the operation of the engine, “focusing” on incorrect TPS readings, and at worst, it will eliminate the TPS readings and light up the “CHEK” light, i.e. error code 41. Both These operating options will adversely affect the dynamics of the car, which cannot but be noticed by the driver.

Vehicle malfunctions due to incorrect adjustment or breakdown of the TPS will manifest themselves in “sluggish” and unreliable engine starting, increased fuel consumption, increased idle speed, and “failures” when accelerating. And in a car with an automatic transmission, “jerking” will begin when switching “speeds”, will not engage or will be difficult to engage in an upshift.

Since Toyotas mostly have automatic transmissions, a malfunction or violation of the TPS adjustment will result in the most widespread and unpleasant defect. It will manifest itself in the absence or delay of gear shifting, which will become especially noticeable when moving from a standstill and picking up speed: the tachometer goes off scale at three thousand revolutions, and the car is still moving in first gear.

Faults associated with TPS (error 41 Toyota) include:

• noticeable increase in idle speed;
• deterioration in fuel efficiency;
• slow automatic transmission gear shifting;
• automatic transmission shifting with knocking and jerking noises
• inadequate response to a sharp press on the gas pedal, etc.

Replacing the climate control unit

If the climate control regulator on a Camry sv20 is broken , then by replacing it you can simultaneously solve two problems - increase the functionality of the car’s climate system and improve the interior. The fact is that in terms of dimensions the climate from 30 is completely similar to the “twenty”. There is a slight difference in the wiring, but the working diagrams for connecting the climate control unit from another car model are more than enough.

In a similar way, you can answer the question of how to make climate control on a Camry America - just replace the faulty unit with a European one. But it is worth considering that errors may occur during self-diagnosis, since American car models are equipped with additional sensors.

Troubleshooting

Self-diagnosis of climate control may be required if the device fails and the normal level of comfort in the car interior is disrupted.

The main sources of problems are:

It is not always possible to visually determine the presence of faults. For a simple check, sometimes it is necessary to completely disassemble the system. If the breakdown is hidden in the wrong place, the driver will be seriously disappointed, because he had to do such work in vain.

In order not to needlessly disassemble the interior, modern systems on cars have provided a self-diagnosis function for climate control. Automakers install approximately identical devices on cars, which simplifies their installation during vehicle assembly, further repairs and maintenance.

There may be some differences between car climate control systems. But mostly it's about power and design. Their operating principle is the same.

Before checking the climate control in cars, be sure to read the operating manual for your particular car. The manufacturer provides recommendations for maintenance and repair, and instructions for enabling the self-diagnosis mode on specific climate control equipment.

Scanner check

Some people test climate control using a plug-in diagnostic scan tool. In this case, the work has the following sequence:

After this, the scanner will begin reading data, and records about the start of diagnostics will appear on the screen. The device will automatically check it and display errors in the form of digital codes.

But external scanners do not always provide accurate information. Plus, modern climate systems allow you to launch a self-diagnosis mode without the participation of external testers and check everything in a matter of minutes.

Checking without a scanner

Self-test instructions may vary slightly. But usually there is no fundamental difference. Therefore, we suggest looking at the procedure for launching diagnostics using the example of climate controls installed on Toyota cars.

If you want to check the current status of the equipment, then proceed in the following sequence:
