I have a 92 ford bronco and recently my red parking light came on and would not go off. I try messing with the switch and everything. It wouldnt go away. Then the rear abs light came on and from there one light would go off and the other stay on or they may both be on. Things seem to switch when everytime I crank the truck up!

Hi bctennant,

Thank you for the donation.

Have you checked the brake fluid level?

Low fluid level would casue the parking indicator light to stay on and when this occurs, the ABS indicator would be triggerred after some driving.

The fluid level is sitting right at the max line. I mean I can still stop. I heard that a common problem was the ABS on the rear diff. Or something like that I just want to make sure I have all possibilties in mind. Any suggestions?

Yes, it could be. When the indicator lights are turned on, trouble codes woulod be triggerred. Here are procedures on how to retrieve the trouble code to understand what could be wrong. Let me know what you find.

Rear Anti-Lock Brake System (RABS) has a self-test capability. There are 2 warning lights, located on instrument panel, to inform driver of malfunction. Red BRAKE warning light indicates low fluid level, parking brake on or low vacuum (diesel models). Yellow REAR ANTI-LOCK warning light comes on when control module detects a malfunction and/or anti-lock brake system is inoperative. Both lights should come on for approximately 2 seconds when ignition is turned on or when cranking engine. See Fig. 12 .

When Yellow REAR ANTI-LOCK warning light comes on during normal operation, a trouble code can be received from control module. Code will be lost if vehicle is shut off before code is retrieved. In some cases, code may reappear when vehicle is restarted. In other cases, vehicle may have to be driven to reproduce problem.

WARNING: Block front and rear wheels to prevent vehicle from moving while trouble codes are being retrieved.

NOTE: If multiple system faults exist, only first detected fault code can be received.

If Red BRAKE warning light is on because of low brake fluid level, together with Yellow REAR ANTI-LOCK warning light, Yellow warning light will not flash trouble code but will glow steadily. System faults concerning brake fluid level switch and power loss to control module, will cause anti-lock brake system to deactivate. Yellow warning light will come on but control module will not generate a trouble code.

Before retrieving trouble code, ensure vehicle is on a level area. Transmission should be in Park or Neutral. Note if Red BRAKE warning light is on. Apply parking brake. Keep ignition on so code will not be lost. Locate rear anti-lock brake diagnostic connector and attach jumper wire. See Fig. 3. Momentarily ground other end of jumper wire. When ground is contacted then broken, Yellow REAR ANTI-LOCK warning light will flash trouble code. A code consists of a number of short flashes and one long flash. Count each flash, short and long to obtain code number.
