the abs and parking break light keep coming on at the same time for no reason while i am driving down the road. if i stop and restart the truck they go way. it has only happened about 5 times but it seems to happening more often.

wtf?

if any one knows whats going please on let me know.

 

I had the same problem with my 04', and I ran a diagnostic because my light stayed on, ran the code on google and found out it was a problem with the grounding system. Basically it said to grind the grounding strap which on my truck was right under the drivers side door, and get a good ground. I did that and ti still came on intermittently. So thats one place to look, but if thats not it, it might actually be what my problem really was.

I had a drivers side wheel bearing going out, and the increased heat was causing the ABS sensor to overheat. The bearing went so slowly that I didnt notice the wheel wobble until it was gone and grinding. I got a new wheel bearing assembly and the ABS sensor is integral to the hub, once replaced the problem cleared and I never had any more trouble.

The ABS system will cause the parking break light to come on, its supposed to alert you to braking problems. So maybe check your bearings. Hope this helps.

 

It could just be dirty front ABS sensors. There is a TSB open for it. Take the sensors out, clean the crude off them and replace to see if the problem goes away. If not you have some other problem.

 

Thanks guys I'll check it out

 

So i got it checked out by my mechanic and found out that the lights are a sign of my brake control module going out. It's a six by six plastic box above the frame near the driver side door. which really sucks because a new one costs about $860.
**** i guess I’ll have to push back getting a stall and gears.

 

do a search...theres a company that fixes abs modules for 150. theres quite a few of us having these problems...i wander if they will do a group purchase for us if we find 7-10 of us that want our abs **** fixed.

 

I believe that the co. that fixes the modules is modulemaster.com...

 

look at your speed sensor on the tailend of your transmission, it will also cause your abs brake light to come on.
