Parking Aid

Pinpoint Test B: DTC C1700, C1703, C1706, C1709, C1712, C1715, C1718 or C1740

Refer to Wiring Diagram Set 131, Parking Aid for schematic and connector information Electrical Diagrams.

Normal Operation - Rear Parking Aid System

The Parking Aid Module (PAM) supplies voltage and ground signals to the rear parking aid sensors. The PAM (Parking Aid Module) receives a signal from the rear parking aid sensors and determines the distance of an object from the rear of the vehicle. If the PAM (Parking Aid Module) detects an open or a short to ground on any of the rear parking aid sensors circuits the PAM (Parking Aid Module) will set a DTC.

Normal Operation - Front Parking Aid System

The PAM (Parking Aid Module) supplies voltage and ground signals to the front parking aid sensors. The PAM (Parking Aid Module) receives a signal from the front parking aid sensors and determines the distance of an object from the front of the vehicle. If the PAM (Parking Aid Module) detects an open or a short to ground on any of the front parking aid sensors circuits the PAM (Parking Aid Module) will set a DTC.





This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- Parking aid sensor(s)

- PAM (Parking Aid Module)
