WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The parking aid system is enabled when the ignition switch is in the RUN position and the REVERSE (R) gear is selected. The Parking Aid Module (PAM) receives reverse gear input from the PCM (gasoline) or Transmission Control Module (TCM) (diesel) through the High Speed Controller Area Network (HS-CAN). A reference voltage and signal return is supplied to the parking aid sensors from the PAM. The PAM receives an input signal from each individual parking aid sensor. The system can be disabled through the message center in the Instrument Panel Cluster (IPC).
NOTE:
If a MyKey™ restricted key is in the ignition cylinder, the parking aid menu is not available in the IPC message center and cannot be deactivated.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Parking aid sensors alignment
- PAM
- Rear bumper
