I've even gone as far as "re pining" the wheel speed sensor cause I though maybe I had a loose connection. I tried tracing the wires from the wheel speed sensor to the next connection (to check continuity) but I can't seem to figure out where the wires go. I can trace them into the main harness but when I go to the large weather pack connector (behind the left front wheel well, under the truck) I don't see the same color wire there???

I'm gonna buy the Alfaobd and see what I can find.
Today while driving the light came on almost immediately after starting but the light went off on it's own a few miles down the road

I got the AlphaOBD today and all my wheel speed sensors are reading correctly. The code I had was c0037 for the left rear wheel speed sensor. According to the AlphaOBD, C0037 had occurred 48 times? I cleared the code and what little bit of driving I did today was code free. I'm at a loss.

After the flash part of the recall, they are supposed to reset the BCM, so it takes the recall. Failure to reset BCM, causes the error. Dealer needs to reset BCM. Problem is, convincing them of the solution.

This only pertains if you had a select recall that updates. Canít recall the recall.
Do you know if you can reset the BCM with Alfaobd?

I found a fix for mine after reading a post on here but I can't find it to forward. Here is the problem that resolved my exact issue:
Get under from drivers door area and look between the transmission and frame. You will see a wire harness that should be secured to a second larger harness. Cut the small zip tie gently (I used nail clippers) inspect the small wire harness for ANY chafing or wear. Disconnect the plug and inspect the pins, ensure they are clean and fully seated. Connect the plug again. You may have to remove some to the strongest electrical tape I have ever touched to expose the wires. I found the small harness had been rubbing on the underside of the body.

Sorry Guys, due to reasons out of my control i have not yet been able to work on my truck. I apologies for not giving an update, on the bright side the light has been off more than its been on. i will be going straight to that plug when i do work on it.
