Abs nightmare

Posted

So I've had my abs light on for over a year now. I replaced the front wheel sensors, the rear speed sensor and the wheel bearings.

I gave up and took it to the dealer and they determined that the module was bad, so I sent it into sia electronics to have it repaired. Installed the rebuilt module in the truck and I still have the light.

I'm too deep to give up now but what other variable could be causing this?

    Update: After a few days with the repaired abs module, the light went away. One more thing off the list

    DRBIII tool is about the only thing I know of that reads the ABS codes. Even my 500 dollar Innova Code reader with both SRS and ABS can't read the Dodge ABS.

My case the tone wheel broke loose from the bearing and free spinning. So below 30 MPH it shows ZERO speed in one hub above 30 MPH it showed correct speed. No amount of ohm testing and wiring test will fix this. You just have to replace both bearings with sensors to be right. 

 

I rebuilt the module at Module masters, ohm every wire, replace the front sensors 3 times for lots of money. The replaced the rear speed sensor. Still didn't fix... Replace both front unit bearings with sensors problem gone.

But these are new bearings. I can you inspect the tone ring without removing the bearing?
