Remove the connectors and look for any loose, damaged or burned pins. Use some dielectric grease for a better connection.

The PCM is also the TCM. The TIPM is another module that controls body functions as well as powers to components.

They control outputs based on inputs.

Internally they talk between themselves, yes.

Okay, so the computer put the transmission in limp in mode (turn off TIPM relay) when it see abdominal input. So it could be any sensor causing that right?
