Hello,
was wondering if someone has the same problems like I do. Been in to the workshop and by hooking it up to a comp they told me that it was from my back brakes sensors. The onlý way to be sure was to pay more money for them to take apart my car. So was wondering if there were easier solutions before leaving in my car again.

much thanks

If the PCM and ABS computer lose one of the ABS sensor input (ie dead sensor) the ABS and TCS light will come on. I have seen a few sensors go faulty on that year of car. There really is no need to take it apart to diagnois it though. It only requires checking the sensor outputs to the PCM with either a multi meter or with the proper scan tools.

expect 1/2 hour diag and 1 hour for replacement
