PINPOINT TEST M: THE DRIVER SEAT MODULE (DSM) DOES NOT RESPOND TO THE SCAN TOOL
Normal Operation
The driver seat module (DSM) 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 DSM. The DSM 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), the power
running board (PRB) module (if equipped) and the parking aid module (PAM) (if equipped). Voltage for the DSM is provided by circuit SBP01 (RD).
Circuit GD143 (BK/OG) provides ground.
This pinpoint test is intended to diagnose the following:
-
