ABS INOP?
 

93Z28,,,

Is there a way to tell if it's a sensor or the ABS unit itself?

When I start the car the light is out, when I start to move the LOW TRAC blinks then the ABS light comes on and stays on.

I checked my tail lights, the ground wires, checked for any burnt/broke wires, that all seems good.

Any other suggestions?

my 97 does same. unable to read with my obd2 scanner. in for answers

Probably need one of those old school snapon red brick scanners with an abs/brakes cartridge since its a 93. Does sound like its a wheel speed issue though since its after moving.

97 should be no problem with a decent obd2 scanner and reading the abs module.
