I'm still struggling with this issue. I've had the relays on the anit-lock pump tested and are fine and the OVP relay is also good. I've even replaced the front sensors and the light is still on.

I tried locking up the brakes on a gravel road today and the anti-lock function is working the brakes pulsed to a stop.

I need and would appreciate any help with this. Thanks in advance!!
