Test J: The Parking Aid Module (PAM) Does Not Respond To The Scan Tool

PINPOINT TEST J: THE PARKING AID MODULE (PAM) 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. Voltage for the PAM is provided by circuit CBP35 (YE/GY). Circuit GD133 (BK) provides ground.

The PAM shares the MS-CAN with the following modules:
- Accessory protocol interface module (APIM) (if equipped)
- Audio control module (ACM)
- Audio digital signal processing (DSP) module (if equipped)
- Driver seat module (DSM) (if equipped)
- Driver door module (DDM) (if equipped)
- Dual climate control seat module (DCSM) (if equipped)
- Heating ventilation air conditioning (HVAC) module (if equipped)
- Instrument cluster (IC)
- Satellite digital audio receiver system (SDARS) module (if equipped)
- Smart junction box (SJB)

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