Pinpoint Test E : DTC B1B36:14, B1B38:14, B1B40:14 Or B1B42:14: Notes
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Parking Aid , for schematic and connector information.
Normal Operation and Fault Conditions
When the ignition is on, the PAM continuously supplies voltage and ground to the parking aid sensors while monitoring a signal circuit for each sensor. If a return signal is not detected from one or more of the front parking aid sensors, the PAM stores a corresponding DTC and disables the front parking aid system.
