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

Normal Operation

The Parking Aid Module (PAM) communicates with the scan tool through the Medium Speed Controller Area Network (MS-CAN). Circuits VDB06 (GY/OG) (MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the PAM. Voltage for the PAM is provided by circuit CBP35 (YE/GY). Circuit GD134 (BK/VT) provides ground.

This pinpoint test is intended to diagnose the following:

- Fuse
- Wiring, terminals or connectors
- PAM



PINPOINT TEST R: THE PAM DOES NOT RESPOND TO THE SCAN TOOL

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
