Parking Aid Module
WARNING: This page is about a different car, the 2006 Mercury Mountaineer and 2006 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The parking aid module (if equipped) is connected to the medium speed CAN. The module controls sensors in the rear bumper that detect close objects when the vehicle is in reverse.
Check the medium speed CAN circuits between the parking aid module C4014 and the DLC C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the medium speed CAN, damage to the DLC C251, damage to the parking aid module C4014, or a problem to an in-line connector.
