Check your front wheel speed sensors.

Re: ABS brake lights intermittedly comes on.
As you can see, i have been away for awhile. I replaced both sensors on each side, but the ABS brake lights. Still comes on and goes off after awhile, while i am driving.

Re: ABS brake lights intermittedly comes on.
None of those codes have anything to do with speed sensors.......
This is a real old system......don't even know if parts are available........if you want to diagnose this yourself, you have to know how to read schematics, and get a GM manual for this, otherwise I recommend a GM dealer.....the other alternative, is remove the system and put "base" brakes in.....or live with it....I assume the base brakes work, you just have no ABS function.... |

In the state of Va, vehicles are inspected once a year, to make sure all safety equipment, are working. If they find the ABS is not working, they can reject that vehicle.

Re: ABS brake lights intermittedly comes on.
I was at pick-n-pull during the year 2019, looking for a part for my wiper motor. The Aurora that I got the part from, also had a ABS brake module on it. So I grabbed that too.
After installing the brake module, the ABS brake light works normal. It comes on at start up, then goes off. The traction control button also works now. |
