Parking Aid Module

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The parking aid module is connected to the ISO 9141 communication network. The parking aid module receives input from sensors in the rear bumper that detect close objects when the transmission is in REVERSE, and the vehicle speed is above 0 km/h (0 mph) and below 8 km/h (5 mph). The ISO 9141 communication network does not function if the wire is shorted to ground or battery voltage. Check the network circuit between the parking aid module C4014 and the DLC C251. Total resistance value must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the ISO 9141 communication network, damage to the DLC C251, damage to the parking aid module connector, or a problem in the in-line connector.
