My son bought a 95 Z28. The ABS light comes on after driving for a couple of minutes. Shut the car off and turn it back on and it comes on again after a short time. All this under normal driving conditions. It doesn't seem to impact brake performance (under normal driving conditions). Im hoping it's one of the three sensors. Is there a way to check the condition of the sensors without a tech1 tool? Maybe using a VOM? Any other suggestions would be welcome. THANKS!!!

 

For starters, examine the reluctor wheels for magnetic debris.

 

I had the same problem in my 1995,a bad front brng hub was responsible.

 

my light did the same thing..
didnt seem to make any differance in the brakes
the light has not come back on since i put new bearings in the rearend.
not sure if it was all the metal fileings on the senser on the differential that i cleaned.
or the fact the carrier is running smooth now.
or maybe it was the connector on the diff..

whatever it was...light is off and stayed off after that was done..

 

Check ur spoiler brake lite I.know it sounds weird but it will throw a code if its burnt out .
