Codes $7E8 an $7E9

Good morning,

These are CAN codes so you have a PCM or BCM that is not working but I have seen these cars needing a TIPM which is easy to replace because it self initializes.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

I did recheck it an code was exactly like this $7E8 an $7E9 an that all it showed.

What kind of a scan tool are you using?

Okay this was the codes.

It says 1 of 3. I only see 2.

You need to go to a parts store and have them read it in the correct format.

Roy

Yea, the third part is the previous menu when you scroll down number 3 is on previous menu only 2 codes.

Okay, got it.

Just in case others have questions on this. This is a pretty common issue on these vehicles. TIPM stands for Totally Integrated Power Module, but this vehicle does not have a TIPM. It has an IPM Integrated Power Module. Slightly different but basically does the same thing.

These codes are very common but they are actually a generic scan tool issue on not being able to read the actual codes that are there.

The most common correction of this is a TIPM or IPM as the circuit boards fail and cause all sorts of different issues. It is very common.

I attached the process below for more info on how to replace it.
