We have a 2008 dodge pickup in the fleet. It had a CEL light due to something idiotic...
Dealer reset the TIPM to erase the code after they fixed the issue.
Apparently, somehow, the TIPM was reset incorrectly, and it decided the truck had a manual transmission, rather then automatic... so when the body control module tried to tell the integrated power module that the transmission shifted into reverse, the integrated power module decided to disregard the information, and not activate the reverse lights.
Installing HID's in stock housings is bad. Here is why.
