Help!

Ok, so you have some obvious codes between the TCU and GWM. The easiest thing to check is to make sure all the connection on the TCU are seated properly. The TCU is located behind the backrest of the back seat on the passenger side behind the trim pieces. Fold down the seat to expose this. Remove the pins circled in red to be able to pull the trim piece down and the TCU is under that bulge circled in green.

TCU looks like this. Check that all three of those connections are properly seated in their location.

Edit: Which module are the wanting to replace? It could also be a bad TCU or GWM. Unfortunately, without FDRS, I can no longer see what the dealer did (or tried to do) which makes things more difficult to diagnose remotely, but these codes in particular COULD mean a bad module:

===TCU DTC U3000:49-49===
Code: U3000 - Control Module

Additional Fault Symptom 49):
- Internal Electronic Failure

===GWM DTC U2402:0A-48===
Code: U2402 - Ethernet Failure With Telematic Control Unit Module (TCU)

Additional Fault Symptom 0A):
- General Electrical Failures - 2

Thanks again for the detailed insight, I really appreciate it!

Heard back today from the dealership that the module is on order and should be here in a few days, unfortunately I didn’t ask specifically which module it was. Full context, this issue first started while I was out of the country and wasn’t part of every communication that had happened in that time, so I’m still trying to piece together everything and get the full report from the dealership as well. From what I gather it was mentioned they were ordering a new APIM module and was what was replaced before.

On that note, would the techs have seen the same DTC codes as well, and investigated the TCM module sooner? Our back seat contains a fairly complex dog cover which covers the seats, sides and floor with a variety of different straps and tie down points, and it shows no signs of having been moved or disassembled to reach the TCM module like in the diagram above. I’d like to believe they would have checked that as well, but it wouldn’t surprise me either!

Yea, they can see those codes with FDRS which is what they use. Ethernet failure means a loose connection since those modules do communicate via both ethernet and CAN bus, or one of the two modules is bad severing the Ethernet connection between each other and triggering those codes.

I’ll give it a look when I get a chance and see if anything looks suspect. I’ll hopefully get a better log of what the dealership has done so far too. I’ll report back as soon as I have more info!
