Here’s a great case study, provided by our friend Michael in Utah, related to a 2010 Dodge Ram 1500 SLT that his customer brought to him for a TIPM reset. As expected from Michael, he dug into the problem vehicle prior to performing the TIPM reset and really didn’t like what he saw, which included no comms with the vehicle’s ABS system (the reason the customer installed a replacement TIPM in the first place).
That sent him down a diagnostic rabbit hole. After doing his homework (wiring diagram review, understanding system function, etc.), he found reference voltage somewhere he wasn’t expecting to find it. This lead further down the hole, but also to the root cause of the problem, which eliminated the need for the replacement TIPM.
Check out the case study to get the full story. It’s a good one.
