I have the TCM on the automatic 9hp transmission, but it not communicate with BCM and ecu 2017. If somebody can help me with modifying the ecu hw001 map to work with 2017 engine hardware. Most important error I can't skip is p0615-15 startup relay command. As I see euro6d have a fuel pump module controller near the driver step door. I don't have this module and the rest of wiring harness for it.
Please make me a price for necessary ecu modifications
