TOYOTA LAND CRUISER 200 – Errors P0046, P0047, P0048, P004B, P004C, P004D

Diagnosing and eliminating Land Cruiser 200 error codes

Land Cruiser 200

Check VSC system in Toyota Land Cruiser 200 is a warning signal from the on-board computer, it indicates an error. Depending on what other lights are on, you can roughly understand what the problem is. But an accurate diagnosis is made after a full diagnosis.

Below we will talk about the most common Land Cruiser 200 errors.

Computer diagnostics Land Cruiser

Computer diagnostics designed to identify Land Cruiser 200 errors can be performed using an EML 327 scanner . The device allows you to identify possible malfunctions. The algorithm for diagnosing using a scanner is as follows:

After removing errors in a special menu, drive the car 4-5 kilometers . The check needs to be run again. Then it will only show the current problems of the Land Cruiser. These errors must also be recorded.

After identifying Land Cruiser codes, the scanner must be turned off, after which the analysis of problems begins. For example, if Check VSC system , then this may indicate problems with the car’s directional stability, or it may simply be a matter of a loose gas tank cap. This is why a detailed analysis is needed.

Question: Installing a mini vci cable on win 10 (there is a problem, no solution)

As a beginner, I ordered a mini vci from China, it arrived, I’m trying to install MVCI Driver for TOYOTA-CABLE 2.0.1, which the Chinese woman sent, but it doesn’t work. It says, it didn’t work, try again and so on ad infinitum. (Attached screenshot)

I googled and came across articles on installation point by point:

1. Go to C:Program Files (x86) and create the XHorse Electronics folder and in it MVCI Driver for TOYOTA TIS

2.From our disk, copy the MVCI Driver for TOYOTA.msi file to the newly created MVCI Driver for TOYOTA TIS folder.

3. Launch the command line (press Windows + R and enter cmd.exe in the window) 4. Copy this text into the command line - msiexec /a “C:Program Files (x86)XHorse ElectronicsMVCI Driver for TOYOTA TISMVCI Driver for TOYOTA.msi” /qb TARGETDIR=C:Program Files (x86)XHorse ElectronicsMVCI Driver for TOYOTA TIS and press Enter. Thus, we unpack our driver for the lanyard.

5.Connect the cable (with the Internet turned off so that it does not download any driver to it).

6.Open the device manager (press Windows + R and enter devmgmt.msc)

7. Find an unknown device with an exclamation mark in a yellow circle and right-click on it and “update driver”. Then select “search for drivers on your computer” and specify the folder C:Program Files (x86)XHorse ElectronicsMVCI Driver for TOYOTA TIS. That's it, we installed the driver.

8.Go to the folder C:Program Files (x86)XHorse ElectronicsMVCI Driver for TOYOTA TIS and run FirmwareUpdateTool.exe. Click device info. If everything is in order, then the status will be connected. 9.Install Techstream from the disk, but do not launch it. Go to the folder C:Program Files or (x86)Toyota DiagnosticsTechstreamEnv and find the IT3System.ini file there. Right-click on it and open it using Notepad. By searching we find the line TISFunction=1 and change it to TISFunction=0. Save.

10. Download this registry file - yadi.sk/d/Ib2oqEysqHuay Launch it and click accept. The registry has been changed, now you need to restart your computer.

11.Rebooted and launched Techstream. In the top menu bar we find Setup, then VIM select. A window will open, select XHorse - MVCI at the top and click OK. That's it, now you can connect the cord to the car and click Connect to Vehicle.

At the third point, it does not unpack for me. What to do help! I have Windows 10.

And if anyone has a Russification of the Techstream program, I will be very grateful.

Car scanners

Land Cruiser diagnostics should be carried out using proven devices. We are talking about scanners:

ScanToolPro is a budget scanner option for reading Land Cruiser 200 error codes. The device scans in real time the operation of all sensors. The scanner is suitable for displaying data on a smartphone screen, which can be conveniently mounted on the panel.

pros:

The downside is that when buying it is easy to run into a fake.

Launch CReader V+ features a bright LCD screen, eliminating the need to connect to a computer or smartphone. In addition to the OBDII protocol, the device is supplemented with another one (CAN data bus), which increases the functional component.

pros:

The downside is that for a number of owners of the Land Cruiser SUV, the device screen is too small.

Delphi DS150E is an impressively sized (noted as a disadvantage) reading device. The advantages are increased functionality, adequacy for many car models (including Land Cruiser), availability of a memory card for recording and storing codes.

Error p1238

When error p1238 appears on the Land Cruiser 200, pay attention to the operation of the injectors . Another option is to reduce the pressure in the fuel supply system . An indirect sign of a malfunction is rattling when starting the engine. The reason on an SUV is damage to the parts responsible for fuel injection. The malfunction may also be hidden in parts upstream of the fuel pump (dirt on the valves).

Code P1248

Error P1248 often occurs when the gas recirculation system is clogged. Both EGR valves can fail at once, which happens when the mileage exceeds 100 thousand km .

EGR cleaning on Land Cruiser 200 SUVs is carried out already at around 50-75 thousand, although you can simply turn off the valves and disable this function at the program level. The procedure for shutting down the system does not require significant budget injections, but it is time-consuming.

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.

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:

DLC 1 connector diagram

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.

Operating principle and features of the PCS system

The operation of the Toyota PCS system is based on the use of scanner sensors. The first is a radar sensor located behind the front (radiator) grille. The second is a camera sensor installed behind the windshield. They emit and receive back electromagnetic waves in the millimeter range, assessing the presence of obstacles in front of the car and the distance to it. Information from them is fed to a central computer, which processes it and makes appropriate decisions.

Scheme of operation of PCS system sensors

The third similar sensor is located in the rear bumper of the car (Rear Pre-Crash Safety System), and is designed to signal the threat of a rear impact. When the system determines that a rear-end collision is imminent, it automatically tightens the seat belts and activates the pre-collision front head restraints, which extend forward by 60 mm. and up by 25 mm.

PCS sensor performance characteristics

If the PCS system determines that there is a high probability of a collision or an emergency situation, it gives an audible and visual signal to the driver , after which he must slow down. If this does not happen, and the likelihood of a collision increases, the system independently activates the brakes and tightens the driver and front passenger seat belts. In addition, the damping forces on the machine's shock absorbers are optimally adjusted.

In its operation, the pre-crash safety system uses the following input information:

• the force of pressing by the driver on the brake or accelerator pedal (if pressing took place);
• vehicle speed;
• state of the pre-crash safety system;
• information about the distance and relative speed between your car and other cars or objects.

The system detects emergency braking based on vehicle speed and deceleration, as well as the force with which the driver presses the brake pedal. PCS works similarly in the event of a side skid .

PCS is active when the following conditions are met:

• vehicle speed exceeds 30 km/h;
• detection of emergency braking or skidding;
• The driver and front passenger are wearing seat belts.

Please note that PCS can be turned on, off, and the collision warning time can be adjusted. In addition, depending on the settings and equipment of the vehicle, the system may or may not have a pedestrian detection function, as well as a forced braking function in front of an obstacle.

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:

TOYOTA LAND CRUISER 200 – Errors P0046, P0047, P0048, P004B, P004C, P004D

Let's consider a situation when clients come to us with a problem - the check light is on, 4LO is flashing, etc., but the car “does not move”, the engine does not pick up speed above 2500. In this case, you need to do computer diagnostics and find out the error codes.

If the error codes correspond to the following designations ( P0046, P0047, P0048, P004B, P004C, P004D) , then this indicates that:

1) The turbocharger control unit or units, which are located on the turbochargers themselves, are faulty. In this case, they can be replaced or repaired.

2) Mechanical jamming of the variable geometry mechanism of the turbocharger, or both turbochargers, is possible. In this case, the turbochargers must be dismantled and disassembled. This is required in order to establish the fact of the malfunction and its cause. There are several reasons for partial or complete jamming of the variable geometry mechanism:

a) ingress of foreign objects from the engine onto the blades of the variable geometry mechanism,

b) deposits of solid conglomerate in the turbine housing (soot, carbon sediment, etc.),

c) natural wear and tear of the variable geometry mechanism.

3) Malfunction of the wiring going to the turbocharger control units.

In this case, everything is clear; it is necessary to determine exactly where the circuit break occurred and replace the faulty wiring. True, the most difficult thing in this case is to find where exactly the break occurred.

4) And now one of the most common causes of errors P0046, P0047, P0048, P004B, P004C, P004D. Malfunction of turbine control units 89878-60050.

These blocks are located under the right front fender, next to the air vents. In simple terms, one of the dirtiest places in the car.

As a result, dirt, water, salt and reagents get on them, which over time destroy the braiding of the block wiring, the sealant of the block cover and everything that comes into contact with.

In the case of wiring, everything is clear - replace it.

If the seal of the unit itself is broken and water, salt and reagents get inside, everything is not so simple. In this situation, it is necessary to diagnose the board, clean it from dirt and water, determine the location of the break, and then solder the contacts and tracks.

After the above procedure, the board is coated with a special acrylic varnish, the block cover is placed on a new sealant and installed in place.

Subsequently, after restoring the turbocharger control units 89878-60050, we recommend moving them away from dirt into the engine compartment. Which in turn practically guarantees that you will never encounter this problem on your car again.

The cost of repairing the control unit is 14,000 rubles. 6 month warranty.
