I guess that's true but my Duster has all new brake hardware and the self adjusters don't work lol. What do you think could cause this abs light it was working fine a few weeks ago

 

2 Open Isolation Valve wiring or Bad Control Module

Check the service manual for 'replacement' procedures, and check fuses/connections. Which truck are you playin' with?

 

The 01 with 96 wiring. I may have found the problem. I will post a pic later but basically the male end of the rear diff sensor (one on frame of the truck) it wire spliced together with those Walmart "quick crimps) and one wire came out. Now I can't repair it because he stripped the quote clear to the plastic housing. So I have to buy the plug from advance Auto when I get home.
