hi Jim. i just bought an 02 diesel superduty, and it has the parking aid system . is there a way to test the system without buying a WDS 418-F224 diagnostic tool as described in the service CD??
the unit is constant on like there is something behind the vehicles, and i am suspecting a bad sensor. when i unplug one of the sensors, it does not work, so i am assuming that the sensors are wired in a series circuit. short of buying a new sensor and swapping out the sensors one at a time to find the bad one, is there any way a D.I.Y'r can diagnose the system??
also, it does not have a trailer brake controller in it. am i correct in assuming the 4 wires on the driver side under the dash at the fuse box are the wires used to connect the brake controller??
