A poor electrical ground under the battery tray may cause the ABS warning light to illuminate. Our technicians tell us that cleaning and properly securing this ground and also the main ABS ground on the frame rail below the drivers door may be necessary.

Abs and brake light stay on all the time. breaks can lock up ! 2 different shops have been unable to fix the problems. I removed the module and inspected the solder joints and resoldered the joints I'll keep you posted
