Speed sensor in final drive is causing ABS and TRAC warning light. Perform an OBDII scan for the engine light.

  • Joe Stanton May 19, 2017

    Notice I said the speed sensor in the final drive. This sensor is reading the ring gear speed in the differential, this speed affects locking function for TRACtion control and ABS. Metal dust is collecting on the sensor. Remove the sensor, wipe off and reinstall to correct gap. Change transmission filter and fluid every 60,000 miles for continued performance. The OBDDII scan can reset this fault as well as the ABS fault. Check for other faults concerning check engine light.

I would think you have a bad wheel speed sensor that is making the light come on. is could be as simple as a broken wire. repair the problem and the light will go out.

Repair the antilock brake system first. That should stop the engine light from coming on. If you don't do the repair, no matter how many times you reset the computer, the engine light will come on. Run a diagnostic test to find out what else is wrong. You reset the computer by disconnecting both battery cables, touch them together for a few seconds then reinstall.

How do I reset trac off abs light on my 03 chevy montecarlo ss. Changed the wheel bearing and sensor

Take it to a mechanic or buy a gizmo you plug into the message control wire by your lower steering wheel and you have to reset the computer. I am not sure the name of the out fit you use but it costs about sixty dollars from an auto store. My mechanic did it for me for forty dollars.

What does it mean?camry 1998 displaying abs and trac off at high speed120km/hr

This means there is a problem with the trac and abs system. the way it works is that when the computer sees a problem with the abs or trac system it turns them both off. also if the check engine light is turnned on due to a problem the computer shuts down the trac and abs system as well due to the computer not being able to control the trac or abs system when there is a engine problem.

The first step here would be to have the computer scanned and get any stored codes out to find out where the problem is. Have the computer scanned for codes first.

My Trac Off light is on and so is my ABS light.

You are going to need to either replace your abs sensors or your entire wheel bearing and the abs sensor will be included... What the abs sensor does is tell the computer when the wheel is turning or locked, if the abs sensor is bad the computer will not know if the wheel is turning or not, so this will also interact with your traction control.
