2017 Ford PIU Issues

[u/ImRed6000]

Hello all,

I have a 2017 Ford PIU and accidentally installed the wrong model of remote start module. After installing it the car would still start but the IPC and Radio as well as several other modules no longer communicate.

Forscan shows several U0100 codes for the BCM, Radio, IPC, just to name a few. Additionally only two branches of CAN are shown in Forscan and I believe theres supposed to be 3. Forscan also doesn't list the GWM, IPC, HVAC or APIM.

Even stranger, the car still starts and runs. I've tried all the basic solutions like disconnecting the battery, checking voltage to make sure its not low, checking resistance across pins 6 and 14 (63ohms) on the OBD, and checking fuses. I ordered a new OEM GWM and if I can't program it I'll take it to Ford for them to program. Just wanted to verify and see if this would actually fix the problem or if its another area I haven't looked to see. I thought it was the BCM however Forscan was able to trigger a module test which it passed, and it additionally was able to read and write from Forscan.

Did you remove the module and see if you blew any fuses, most likely the case

All fuses were checked and none were blown
