MM3 Tuner - ECM Communication Error - Code 18504

[AK Bob]

I'm looking into getting an Innova 5610!

Any thoughts on that one?

I haven't had any experience with it to compare.

Hopefully, others will chime in.

I recommend a tablet-style scan tool with a CAN bus topology, such as the Autel, Thinktool Pro, or Topdon.

I'm getting code U1601- ECU application software CPDE 1 missing or corrupted, U0101-TIPM lost communication with TCM, U0100-TIPM lost communication with ECM/PCM, U0141-WCM lost communication with IPM (FCM/TUPM), 3 different open circuits in TIPM.

OBD2 scanner was able to read and clear codes!

Sounds like the TIPM, do the codes return, can you communicate with any other modules?

Sorry, I meant the scanner can clear codes as a function!

Those codes come back, but others from disconnecting the battery cleared and didn't return.

I can read codes from ABS and SRS, and it says my TCM doesn't support the reading DTC function.

I am not sure if that's the cause of the scanner.

Yes, I don’t know either.

It’s a tough call, and you may have multiple problems.

The codes show lost communications with the TCM, ECM & IPM, but you can communicate with the ABS & SRS.
