ABS / BRAKE Light

[Mopar1973Man]

Once again I got that darn blasted ABS and BRAKE light again. I knew the driver side front sensor was repaired. What had happened was the outer jacket of the ABS split open after being flexed enough times that it broke. So the driver side was soldered and shrink wrapped and tapped up well. So I pull the driver side thinking it was damaged and unwrapped the repair and everything was fine. So I broke out a DVM and set it for ohm setting. Sure enough the driver side was right around 1,000 ohms. Hmmm... So quickly yanked the plug on the passenger side and ohm that lead. I got infinite ohms (open circuit). Now start from the sensor and right about the knuckle the jacket did the same thing. Split open and the black wire was broken. Very carefully I took a razor blade and took just a little bit of jacket off so I could solder and shrink tube this side. So after the repair I checked the ohms again and right around 1,000 ohms. I placed a dab of dielectric grease in both ABS plugs and plugged them back in. Roll the truck out of the shop and about half way across the yard the ABS and BRAKE light went out.

 

I think the next time its going to be time for new sensors...

When extremely wet like driving through slushy snow my ABS light comes on. Only has done it a few times in the 3 years I have had the truck. So intermittent that I have not dealt with it yet. Must be an electrical connection or open insulation like michaels. Doing front brakes soon. Will look for problems with sensor connections/insulative sheath then.

Mine was very obvious of the break. You could flex the jacket and clearly see the black wire was broken and the white wire was intact. I would suggest you inspect the plugs it might be corroded contacts.
