Ford Repair Questions? Ask a Mechanic for Answers ASAP
I know on my 2005 F350 with park assist, there was or is also a park assist switch on the dash, did you also install that?
Actually, after looking at the wiring diagram, I don't see one.
I do see a fuse though, so check the f34 fuse in the body control module.
that fuse I mentioned is the power supply.
make sure you use a voltmeter or 12 volt test light to check both sides of that fuse, with the key on run.
Did that answer your question? If so, kindly leave me a positive rating, so I get credit.
Perhaps with a scan tool and reflash the software in the body control module. Let me see if I can find an answer to that, give me a few minutes.
Check for power to the module, here at step R1,
I don't see yet that it needs anything from the body control module except for voltage from that fuse you checked, so unless the park assist module itself needs to be reflashed, I would check those steps mentioned it that article first, then let me know if a scan tool cannot communicate with that park assist module. I do see it has a wire going to the dlc, so it appears that park assist module communicates directly with a scan tool from the dlc.
I just read this, too, "If the vehicle is equipped with an integrated electronic Trailer Brake Control (TBC) module and a trailer with electric trailer brakes is connected to the vehicle, the parking aid system is disabled."
So make sure if you have that hooked up, to unhook it.
Any luck yet?
