PINPOINT TEST P: THE CLIMATE CONTROLLED SEAT MODULE DOES NOT RESPOND TO THE SCAN TOOL

P1-P2:

P3-P4:

Normal Operation
The climate controlled seat module 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 climate controlled seat module. The climate controlled seat module shares the MS-CAN network with the instrument cluster, the smart junction box (SJB), the electronic automatic temperature control (EATC) module (if equipped), the audio unit, the THX(R) amplifier (if equipped), the satellite radio receiver (if equipped), the parking aid module (if equipped), the digital versatile disc (DVD) player (if equipped), the driver seat module (DSM) (if equipped), and the power liftgate module (if equipped). Voltage for the climate controlled seat module is provided by circuit SBB16 (VT/RD). Circuit GD145 (BK/BU) provides ground.

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Climate controlled seat module
