the 2 bad parking aid sensors on my 02 F250 have been replaced, and the system now works, sorta. when cold it works fine. as soon as i build any heat in the cab, it goes solid tone. do you agree that it sounds like the module is bad??
not sure. i have an auto X- ray scan tool, but i gives me no codes on the truck. and the troubleshooting procedures in the service manual are kinda hard to follow.
I took a quick peak at Auto Xrays website and I see they have many flavours of code readers/scanners... The PSDs (even the 7.3s) aren't really OBD compliant.... They do use the 16 pin OBD2 style DLC, but not all scan tools can read diesel data.... From what I saw, I doubt that the Auto Xray can do proprietary modules (PAM, ABS, ICM, et al).
I've worked through many park aid concerns and all were fixed with either sensor replacement and/or rear harness replacement - the rest of the system just hasn't presented me with any other concerns. That's not to say that a wire couldn't be pierced by a screw or the harness couldn't chaffe or be trapped under a washer in one truck or another... but a code scan with a capable tool *could* reduce the frustration factor....
Jeez... you gotta stop top posting... I'm told it's "rude"....
