Test O: The Parking Aid Module Does Not Respond To The Scan Tool

PINPOINT TEST O: THE PARKING AID MODULE DOES NOT RESPOND TO THE SCAN TOOL

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. The PAM shares the MS-CAN with the instrument cluster (IC), the smart junction box (SJB), the heating ventilation air conditioning (HVAC) module (if equipped), the audio control module (ACM), the rear entertainment module (RETM) (if equipped), the satellite digital audio receiver system (SDARS) module (if equipped), and the power running board (PRB) module (if equipped). Voltage for the PAM is provided by circuit CBP18 (GY/OG). Circuit GD145 (BK/BU) provides ground.

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- PAM
