Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the Check Engine, Service Engine Soon, ABS, VSC Or TC lights to tell you that there is a problem and you should have the car diagnosed and repaired. When there is a problem with the engine control system, any other systems that communicate with the engine control module (ECM) may turn on their indicator lights at the same time because a code has been stored in the ECM. I would take it to a service center you trust and let then come up with a solution. Sometimes a problem in one system will turn light on for other systems that communicate with it, but it doesn't mean there is a problem in those systems.

Please let me know if this information is helpful. Positive feedback is appreciated. Thank You!

SOURCE: I just had a few warning lights come on in my 08

Hello. Those three lights are all designed to illuminate when you have an issue with the electronic sensors on the engine. To properly identify the reason for the lights being on, you will need to get your vehicle hooked up to a scan-tool. AutoZone provides this service for free. Get the car scanned, and get the codes stored in the memory of the car's computer back to us for further assistance.

SOURCE: VSC and Malfunction Indicator came on and stays on

When you say malfunction indicator , do you mean `check engine`` light.
These paired lights can indicate a change in engine air flow and fuel mixture. Try a fresh tank of premium fuel, but first a unscrew and re-screw the gas cap until it ratchets into place. The lights can be triggered by a loose gas cap, a fouled O2 sensor, and several other emission related problems including sticking throttle body components, etc.
This can sometimes be sprayed with carb cleaner inserted in the snorkle area of the air intake where teh snorkle meets the metal intake.

Testimonial: "Thanks for the reply, it was a loose gas cap once tightened it all cleared. This was very helpful."

VSC and ABS lights come on while driving , vehicle starts running rough with a little jerking feel


Toyota has had problems with their throttle systems, I have never seen an accidental, unwanted acceleration, but I have seen pedal and throttle position sensor codes several times with theses systems. You need to scan the car for codes, as there are several hundred. The VCS and ETS are all part of the same system, that being the power train control. Take it to a Auto zone for a quick scan or you can buy cheap scanner online that will give you just the codes to Google the problem. Since you have an ETS light which is a malfunction with the electronic throttle control, then you will get a check engine and a VSC light as well as they are all dependent on a properly working electronic throttle system. Good Luck :)

If you have MIL get the codes scanned, at least they will help point you at the real cause of the problem. For the moment ignore the VSC warning until the MIL has been successfully diagnosed and cured. Nine times out of ten curing the MIL will resolve the VSC warning.

We are looking for a sensor unit diagram for VSC , trac off, and malfunction indicator lamp (they are all on when engine is on and off when ignition key is off.)


You need to have it scanned for codes for the check engine light. Don't worry about the VSC, and TRAC Off lights, THey are on because the Check engine light is on. Once you clear the code for the check engine light the other two lights will go off.

Vsc, engine and track off light are on the dash board, what could this indicate?


VSC is for "Variable Slip Control" and TRAC is for "Traction Control". Your car is equipped with an antilock brake control system that is also equipped with VSC and TRAC. If these lights are staying on all the time, it is an indication that there is a malfunction in the system and your car will not function properly in the event that you get into a situation where evasive maneuvers are needed and/or slippery conditions could cause you to lose control of your vehicle.

SYSTEM OUTLINE

The vehicle could be in an extreme over steering or under steering tendency due to unexpected accidents, road conditions, vehicle speed, or by other external factors. In such a case, this system automatically controls the engine output and the braking to each wheel, to decrease the extreme over steering and under steering.

  • To decrease extreme over steering tendency When the system determines that the over steering tendency is large, the system applies brakes to the outer wheels according to the degree of over steering, and creates a moment towards the outer side of the vehicle, to decrease the tendency of over steering. Also, when the brakes are applied, the vehicle speed decreases while the stability increases.
  • To decrease extreme under steering tendency When the system determines that the under steering tendency is large, the system applies brakes to the front or rear wheels according to the degree of under steering, to decrease the tendency of under steering.
  • VSC OFF SW The SW to send the VSC system into OFF mode. When the SW is pushed after starting the engine, the system will be in OFF mode, and the VSC off indicator light will turn on. When the SW is pushed again, the system will be in standby mode. When the engine is stopped and re-started, regardless of the VSC OFF SW, the system will be in standby mode.
Information to the driver
The VSC system informs the driver when the tire grip is about to exceed its grip capacity, by blinking the slip indicator light and turning on the buzzer. Accordingly, the driver is informed to drive more gently.

**************************************************************************************************************************
Diagnosis of this problem needs to begin with a scan of your VSC and Traction Control and ABS control modules to retrieve fault codes. It could be anything as simple and painless as a malfunctioning Wheel Speed Sensor, or something as expensive as a damaged Hydraulic Control Unit.

What is a vsc warning light on a toyota estima hybrid ?


It stands for Vehicle Stability Control When the VSC system takes control it activiates stability correction. The slip indication light flashes while the buzzer activates. The VSC is able to operate at all times except when the centre differential is locked. When the centre differential locks, the VSC-OFF light in the combination meter illuminates to inform the driver that the VSC function has been turned OFF. The centre differential lock is designed for freeing the vehicle if it is stuck in mud for example, however it would be difficult for the vehicle to free itself if the engine output were reduced due to the operation of VSC. Therefore when the centre differential is locked, the VSC function is turned OFF.If a malfunction occurs in the VSC system, the VSC warning light illuminates to alert the driver. If the vehicle with VSC begins to oversteer or understeer because of an emergency avoidance measure, or by excessive speed in a corner, VSC will automatically activate. By adjusting the engine’s power output and braking each wheel independently, VSC helps to return the vehicle to a ‘zone of stable operation’..

Warning lights


On a Prius, when the check engine light comes on it indicates a malfunction in the powertrain control system. You need to have the car scanned for codes to see where the fault lies. The red triangle lights because the check engine light is on. The VSC is disabled when the check engine light is on and that light comes on.
Start with having the car scanned.
