Reading a few posts on the seats but found very little info. Hooking up DAS but no communication with the unit. Is this indicative the module is bad or could it be something else?

Run another quick test-----then did you double click on the seat control module result!!

Yes...same result. Someone suggested it could be a bad module housing the seat warmer and other controls.

Post the VIN!!

Thanks!

After reading GF9130P3005T and VIN code 401,I agree that the lack of communication is because of the faulty control module N25\7 located on the cross member under the drivers seat.

The module is on the CAN B(interior bus) and is faulty because it is not putting data on the bus(communicating) !!

That's my take!!

Amazing diagnostics Plutoe! Attached is the finding, exactly what you suggested. Now I have the task to get the module out. I was hoping it was on the dash, under the radio. Is the module repairable, if not is it only a stealership item?

This must be the N25/7 module on the cross member that pooed the bed. Poor decision to place it!

Plutoe

you got it!!

I wanted to confirm module part number 2118702026 for heated and ventilated seats.

the left seat control module 25\7 is the part you want(211 870 46 26)-maybe you can find the older versions on ebay they are 211 870 40 85, 01 26, 89 85, 17 26 !!
