Trac Off, ABS, and VSC indicator lights are on...I was involved in a front end fender bender but nothing major just the fender and bumper damage. but these lights would not go off. 2010 Toyota Sienna LE...


It is very common for all of these lights to come on all at the same time. They are all related to your Antilock Brake and Traction control system. ABS = Antilock Brake System, TRAC OFF = the traction control system is disabled - either because there is a malfunction in the ABS system or you have turned off the traction control button. VSC = Vehicle Skid Control. - (which uses the ABS and the Traction Control to function.)

The most common cause of these lights coming on is one or more defective wheel speed sensors. Although there are many other possible causes as well. Your ABS and Traction Control system must be scanned for fault codes to diagnose the problem. If you had damage to your wheels/axles during your "fender bender" this may have something to do with it. Otherwise it may just be coincidence that part of these systems failed right after your accident.

My trac light is on, on the dash board. Where is the wheel sensor located ?


Your vehicle is equipped with 4 of them. They are located at each of the 4 wheels. There are other reasons that the Traction Control light can come on...wheel speeds sensors are not the only reason, athough they are the most common. The traction control system works with the engine/powertrain control system and with the antilock brake system. A bad wheel speed sensor will usually also turn on the Antilock Brake (ABS) light. If the Check Engine light is also on, you could have an engine control problem causing the Trac light to come on.
.
If the Trac light is on by itself, you may just have the traction control turned off. The Trac Off switch is located on the steering column.

If none of the above solves your problem, then you will have to scan your computer system to find out why the light is on. ( i.e. failed wheel speed sensor...but which one?)

My traction control lights keep coming on, and then my car says that the engine power is being decreased, and i'm on dry surface


That is your Antilock Brake/Traction Control computer going into what I call "False antilock mode" This is almost always caused by abad wheel speed sensor. Your vehicle is equipped with 4 of them. To diagnose this problem, you must drive the vehicle with a scanner hooked up that can read the wheel sensor data and find out which wheel sensor is not working properly. Sometimes (but not always) you get lucky and the Antilock Brake Control Module will set a code to tell you which one.

What does the TCS Off button do?


TCS stands for Traction Control System.
The traction control system works in conjunction with your Antilock Brake System (ABS) and your Engine Control Module (ECM) or Powertrain Control Module (PCM) or Electronic Control Unit (ECU) (Note that ECM, ECU, and PCM all mean the computer that controls your engine, depending on make.)

Anyway, the traction control system can apply one or more of the brakes and control engine RPM in the event that a wheel slip has been detected by the traction control system.

Pushing the TCS button on most models will light a lamp in the instrument cluster that usually says "Trac Off" Pressing it a second time will turn this light back off.

When the "Trac Off" light is illuminated, the Traction Control System is disabled and will not work in the event of a wheel slip.

Also note that when the Traction Control System is working and a wheel slip is detected, The Traction Control Module will usually illuminate a light that says "Trac" as it is taking control of your brakes and engine. It can feel really strange when this occurs and some people think that their transmission is slipping or that their engine has a misfire problem.
The chances are that if it occurred on wet, slippery pavement, the Traction Control System may have just saved your life.

If this is happening on dry pavement and normal driving conditions (starting, stopping, or turning), there may be a problem with the system. "False Traction Control" can happen just like a bad wheel sensor causing "False Antilock Mode".

Also check your Owners Manual for more specific information pertaining to your particular vehicle.

ABS / ETS lamp on dishboard appear to my mercedes E320 96


Have your brake pads and rotors checked if you have worn pads this will activate the ABS Antilock Braking System light. The ETS Electronic Traction System uses this ABS to prevent skidding if the tires should lose traction.

ASC & ABS light on cluster


Check to see if your brake pads and rotors are in good condition. Or if you have replaced the pads yourself and have not reset the wheel sensors this would cause the ABS Antilock Brake System light and the ASC Automatic Stability Control light to stay on as the ASC uses the ABS brakes with computer assistance to control the traction of the car if not fixed it can effect your rev limiter slowing performance
