ABS/Traction control lights on. A brief history. 2016 2500 6.7/auto longhorn
Issue started over a year ago. Lights would come on intermittently. Dealership scanned it, driver rear speed sensor. I replaced the sensor twice and it didn't stop happening. After banging my head researching the forums and testing wiring, fuses etc. I dropped it off at a very reputable local shop. They had the truck for 6 weeks. Replaced the hydraulic control unit and abs module. Didnt work, rams guideline says replace it again, didnt work. And again. Reset PCM, rewired the rear sensor, and banged their head. Eventually they gave up. Magically a week later the lights turned off and stayed off for quite some time. Flash forward to 2 weeks ago, lights flashed after slamming on the brakes in the rain with a trailer. Went off, came back on the next day, and are still lit. I replaced the sensor again today thinking maybe it actually failed this time, no luck. So back to scouring forums for the same issues. Checked the tone ring for play while I had the sensor out, and it was fine. When I pulled the sensor out today it was loaded with grease and possible shavings which I don't recall before.
I'm at my wits end, and tired of chasing a ghost issue. It's always the driver rear that throws the code, never specific conditions. I've dumped alot of money and time into this, and been without the truck way too many times. Tried to file a claim with FCA a year ago and got ghosted. If it wasn't for loving every other part of the truck, I would have sold it along time ago.
