ABS & Trac Lights on

Post by geomart »

My ABS and Trac lights keep coming on, and sometimes it will not let it shift. I had a scan done and it said that the left read sensor was not being read. I removed and cleaned all four wheel sensors. Checked the ohms on all, all within specs. Lights continue to be on sometimes. Does this mean my ABS module is bad? Or is there something else I need to check? Thanks geomart

What year is your car? '96 and on it is 99% that the ABS module is bad. You can fix it yourself or send it out for a rebuild.

Sorry 97, 850, 96,000 miles non turbo. The only thing I haven't checked is the break switch. I haven't had any problems with it until now. My daughter still drives the 83, 240, 180,000.

EVERY SINGLE ABS module goes bad from 1996 thru 2001
Just remove the module and send it along with $100 to:

That IS your problem
