Description of the Vehicle Stability Control (VSC) Toyota Land Cruiser Prado 120 / Lexus GX470 since 2002

How and when the VSM system is activated

This system is used as an add-on over other traffic stabilization aids, and automakers usually define it in their descriptions as an addition to their list. Existing indicators can be used to signal activation, for example, ESC and EPS activation in Hyundai Accent or Creta.

Active Steering mode is switched off when driving in reverse or on a slope. Speed ​​limits for inclusion are speeds above 15 km/h on a road with turns and above 20 km/h when braking. You can disable or enable this mode manually by pressing the ESC OFF button. The activation of the equipment is felt by ear and by a slight pulsating movement of the brake pedal.

VSC System: what is it on Toyota and Lexus

Tire tread wear, weather conditions, and incorrect driver actions are the reasons why a car can skid.
The wheels lose traction with the roadway, and the rear part of the car is pulled by the lateral force to the right or left of the motion vector. Sudden movements of the steering wheel, emergency braking or disengagement of the clutch aggravate the situation: the car begins to spin, and when colliding with an obstacle (curb, snowdrift) or driving into a ditch, the car may tip over. To avoid such a situation, engineers at the Japanese automaker Toyota have developed an electronic system that reads the readings of several sensors and helps the driver prevent the car from skidding. The system was called VSC System.

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.

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:

Troubleshooting

To troubleshoot problems, you need to visit a technical service center or an authorized dealer. There they will conduct a check and computer diagnostics. Reading the error code will help determine the cause of the malfunction.

Is the problem resolved? Now I have the same combination that lights up, but it doesn’t light up all the time, and a couple of times the trc Activ light came on on the dashboard and the pads grabbed the wheels, and on smooth, dry asphalt. While I’m driving like this.

No, I haven’t decided, I’ve been going somewhere for a month now,

And I thought it was no longer fashionable to drive like this

Oooh PROVET )))) The same crap))) but my front left ABS sensor has died, since October somewhere)) I’m driving and somehow I like it better, I started to feel the car better, much better, I’m not talking about the dimensions, but about what’s in her Soul, it’s much more powerful than with these sensors, and after riding for so long to put it on, I even think now, I understand it’s necessary, safety and the rest, but it’s as if he breathed into all his lungs. Exactly in its entire volume... but without a pillow)))) only three light bulbs)

The VSC light came on in the car

One of the reasons why the VSC check engine lights come on is due to a faulty steering loop, but if everything is fine with it, you should take care of calibrating the directional stability sensor. And since there is an opinion among many that such a procedure cannot be performed, we will try to dispel this myth and understand the sequence of eliminating the problem.

However, it is worth noting that some owners do not want to do this, simply replacing the sensor with a new one. However, the cost of the sensor is steep, and therefore it would be useful to know how you can really save money.

Certain Toyota models equipped with the VSC (ESP) system indicate by the corresponding lights that problems have arisen, indicated by the following fault codes:

• C1336 (39) — Calibration work to zero the deceleration control sensor was not performed;

Payment via Yandex Cashier

After selecting payment via Yandex, the Yandex Cashier payment system will launch, where you need to select a convenient payment method (bank card, QIWI, Yandex Money account, etc.)

After specifying payment details and confirming payment, payment for the goods will occur.

If you have a bank card in a currency other than the ruble, then the money will be debited from the card at the rate of the Central Bank of Russia at the time of the purchase.

This payment method is optimal for residents of Russia, Kazakhstan and Belarus.
