I have a 1994 F150 5.0 2 Wheel Drive. I cannot get the ABS light to go off. I replaced the rear speed sensor and the module is working properly. All the wiring looks good and I even did the ground text, with the ABS light flashing 16 times. I don’t believe the front wheels have speed sensor ( nothing there). Please help.

 

Fuse #13 I think could be flaky

 

Hey, I have the same issue on mine (95 5.0 2-Wheel Drive).

Do you ever have yours turn on and off?

I've checked the wiring and sensors and everything is okay. My mechanic has said it could be the module.

 

Hi, mine has not turned off and on. I even replace the module and that did nothing. All fuses are good. I’m stumped.

 

My light comes on after driving over 55. Drive around town all day and it never goes off. I occasionally get the pulsing brake pedal when stopped. I've bleed everything multiple times. At 25 years old, it may be the ECU or ABS module but at this point I'm not putting hundreds in to fix.

 

Have you checked for diagnostic trouble codes?

Could try shorting brake fluid level switch wires, also could be speed sensor on the rear differential sometimes new parts defective...

 

Do the pinpoint tests for the RABS in the service manual for the code outputted from the module when you ground the wire
