Jeep Cherokee ABS Light Is On

Q. Vince, I have a 1992 Jeep Cherokee Limited 4.0 lite automatic transmission. The ABS warning light comes on every time I back out of the driveway and start down the street at about 5 to 10 mph I hear a little whirring noise under the hood on the drivers side, where the ABS PUMP and booster unit is located, and then the ABS light comes on.

I know there was a problem with the control module on this vehicle. The fault code comes up ABS pump failure. Is there a way I can check this out before going through the costly repair of replacing the pump or the control module, to find out which is causing the problem.

Also, the Brakes work just fine I have great pedal pressure and no pressure loss when I press the brake pedal. Any info you could provide would be greatly appreciated.

Thank you,

A. When there is an ABS failure, the system defaults into standard power brakes. So no matter what fails in the ABS system, you will always have brakes.

Without the actual DTC, there is really not much I can do for you specifically. It could be a problem with the ABS pump, ABS Hydraulic Control Assembly or ABS Control Unit.
