So I recently purchased a 2013 2500 with the 6.7. With the really cold weather we recently had, I started having issues with my TPM sensors. I bought an obd dongle (obd link mx+) and got alfaobd with the intention of disabling the TPMS and converting to LED lights.

After changing some of the light settings, I moved on to disabling the TPMS. I pulled up a video on YouTube (1st mistake) and followed everything to a T. The last thing I did was perform an rf hub reset/relearn and all hell broke loose after that. Service abs came on, parking brake light came on, fuel gauge went from full to half, low fuel light came on, trac control doesn't work, cruise doesn't work, heated steering wheel doesn't work, the spot where it shows if I'm in park, reverse, neutral or drive just disappeared. My trip odometer disappeared and the list goes on.

The truck runs and drives just fine.

Now the question is how do I fix it or do I have to take it to the stealership?

I could find answers in other threads

Went to abs initialization and the start button grayed out. Tried doing the static ECU initialization and when I hit start it says "coding data not received" and it fails. Any settings that I changed, I changed them back. I disconnected the batteries for about an hour and nothing changed. The fault code I'm getting in the abs module is C2206. Vehicle configuration mismatch.

I'm at a complete loss. I'm kicking myself for not doing more research first.

Any insight would be greatly appreciated.

Very 1st question to answer is did you do a backup prior to putzing with the settings? Why are you trying to initialize the ECU?

Sounds like there is a comms error on the canbus.
