So I've recently got an elm327 cable and forscan to add autlocking doors to my 2017 Focus titanium x 1.5 diesel before I done anything I done a DTC read and the car had a few fault codes to do with the right indicator which was no big issue. I went ahead and added the auto locking doors onto my car went back and done another dtc read and the car has thrown up alot of codes, I'm not sure if these codes have appeared as a result of the car shutting down to add this feature and the ecu is just storing these codes as it couldnt communicate with certain modules at that time.

Ive thought about just clearing these codes and going for a drive and re testing it thiught id check with the forum first.

Also a note there is no warning lights on the dash and everything seems to be working as normal.

Just due to a bcm rewrite.
Clear them all.
