Anyone have integrated power module failure? Mine burned up at the transmission relay.
I was diagnosing why I was in limp mode and had transmission relay codes P0888 and P0891 and discovered the melted relay. I disassembled the IPM and found the circuit board burned. It has an open circuit for the transmission relay ground and the relay is melted.
Just would like to know how common this is? The part is about $250-300 new. I may try a "hack" of sorts by bypassing the bad part of the circuit board just to get the vehicle on the road until I can get the new part.
Thanks in advance
