Park Aid Fault - Rear

[JGee]

Hey I am now getting a Park Aid Fault in the IP cluster. I connected Forscan and I am receiving 4 error messages, B1B44:31-2A, B1B46:31-2A, B1B48:31-2A, and B1B50:31-2A. I am also seeing a no signal message, which I am guessing that all 4 rear parking aid sensors are not communicating to the Park Aid Module, or PAM. Any suggestions? Harness or connector issue between the PAM and sensor harness? Any suggestions are appreciated.

DM me your VIN so I can look at VHR. Any programming, OTAs, aftermarket parts on there or did this just happen all at once?

Could be a wiring issue as Ford routed these wires between the rear bumper and fender. Happened to me in the most annoying way possible. See this thread:

Dealership fixed wiring under warranty - replacing the harness was way too involved, so they fixed up the wiring and relocated it a bit to a non-rubbing spot.

Visited the dealer today for the same issue. I was told the wiring was a mess and was chafed from rubbing against the frame somewhere along the right side. Took about 3 hours total to repair. Was covered under warranty and said they would be billing Ford about $500.
