96 Ram 1500 5.6L rear wheel abs. I am getting code 2. Anybody know where could cause this?

 

Special build?

 

2 Open isolation valve wiring or bad control module

 

I have the FSM just was wondering if anybody has that code and knew what fixed it. It turned out to be Ground G107 but the PDC. Now I have code 9 and I just put in a new sensor lol

 

When mine goes in for alignment on Tuesday, I told them to check out the abs system for me. I replaced my rear sensor back when I got the truck, that took care of the speedo problem and the lights went off. But they were on again after I let the brake system drain out completely dry. Not sure if its my proportioning valve getting stuck or the rear sensor is covered by whatever is going wrong in the rear end... I should probably pull that sensor and see if there is metal on it.... Once I get the front axle/steering sorted out, the rear axle is next in line.

 

Yeah makes 12,000HP
Every time I fix it, it lasts about 3 months

 

The wiring harness to the rear diff speed sensor usually rubs on something about 50% of the time. Most of the time its rubbing the parking brake cable.

 

I repaired that the first time when I first got the truck. The silicone wire harness had a break in the one wire but the silicone was fine. It is rigged as the plug on the frame fell off and it was hard to put it back on with the gas tank there. When I can make it to the junkyard I plan on pulling the plug and the harness. Then I'll drop the gas tank to solder on the new plug.

 

For Code 2 my fix was ground G107 by the PDC the bolt won't go right. But now I have Code 9. Not to worried about it other then the lights being on. They don't come on right away, they come in about 6-9 seconds after the vehicle has started. Where before they came in right away. Black electrical tape might be the fix for now over the lights
