2nd Gen Non-Engine/Transmission ABS / Brake light - Not the same old problem

[CTLindsey]

My Brake and ABS lights are on. I have 4 wheel ABS. I tested the rear speed sensor and it was good. I checked the wiring and it is not damaged. I fixed a vacuum leak above my turbo and now my AC vent selector works. But my lights are now on all the time. First it was intermittent and then it went to on most of the time and then it would go off on left hand turns and no it is stuck on all the time.

I just found that the bolt is missing from the left sensor where is attaches to the knuckle. My question is does this sensor need to be grounded with that bolt and is this my problem?

I have ordered the bolt but it comes in on Thursday night and I am heading for a trip on Friday morning. I am Hauling a load over the grapevine in the rain on Friday and would like ABS for that trip. Should I keep looking or did I find my problem? The sensor seems to be held in but it does rotate a little. After I put the bolt back do I need to adjust the sensor or recalibrate or do anything else? Thanks for your replies in advance.

Do you have cruise control and does it work? If not it may be the clock spring. Worth a look-see. Mike

Yes i do have CC and it works as well as the spedo. How do you fix a clockspring?

The clock spring maintains contact with the electronics of the steering wheel as the wheel is turned. As your CC works this is not a concern. I just mentioned it because of the LH turn making the problem show up.



The grounds on our trucks are important. Try fixing the loose harness on the LH side and let know if that does anything for you. Mike
