My truck recently got a check engine light and simultaneously popped the message "service shifter" on the dashboard. I took it in to the dealer the next morning. They hooked up their code reader and reported to me it was a generic communication code that was not active. They cleared the code and charged me 100$ and told me to come back if it happens again. The next day the same code came on. I then used my OBD reader(not ready to drop another 100$ just yet) to retrieve the code. It was U1467. I tried looking up this code but it does not appear to be in any of the online databases. I know the U indicates communication and the 1 means vendor specific but I have know idea what the remainder of the code indicates. Any help would be greatly appreciated and please let me know if I can provide any additional info.
