88 anti-lock brakes
My dad just gave me his 88 c4 corvette. The anti-lock brake light on would turn on and off over the course of about a year and then it has stayed on for about the past year. He replaced the brake pads thinking that was the problem, and it did not fix. Where should i begin to inspect it and/or repair it? I am mechanically inclined and have a general knowledge of car mechanics.

The abs controls are in a compartment behind the drivers seat. Under the speaker.

Probably should consider buying a FSM. I have an 89 FSM. I will look it up in my FSM

When Anti lock malfuction occers, check: control module connector is securely connected.
Check all abs connectors
Check "brake" fuse
Check "GAGE" fuse
If prem. checks do not correct, use J 35890 ABS tester to properly diagnos.
Good luck

This is a start, but the GM Shop Manual will have detailed wiring diagrahms and step by steps checks. My ABS was a complete disaster. I fixed it using the book and a multi meter, without that special ABS tester that is almost impossible to find now.
