Thread: Troubleshooting ABS/Trac Control off

I think I am having the same issue. Only my ABS/Trac Off light comes on if I make a sharp right turn. So I am thinking it is a connection/wiring issue. If I drive start or make no sharp turns the light does not come on.

How do you get to these sensors to clean them?

Also, took it to OReilly auto parts to borrow their scanner to see if it threw a code and no codes come up. Maybe their scanner can't read ABS codes?

This is on a 2002 Grand Prix SE - 3.1 liter FWD.

I just unplugged the connector from the wheel hub, and wiped it down with a clean microfiber cloth. Compressed air may help as well.

I found a TSB described here that might help you as well. Good luck!

I had issues reading the codes once the vehicle is restarted.. they seem to clear quickly.
