Normal Operation
The Medium Speed Controller Area Network (MS-CAN) uses an unshielded twisted pair cable, circuits VDB06 (GY/OG) and VDB07 (VT/OG). The
smart junction box (SJB), the HVAC module, the Audio Control Module (ACM), the Driver Seat Module (DSM), the Rear Entertainment Module
(RETM), the Satellite Digital Audio Receiver System (SDARS) module, the Liftgate/Trunk Module (LTM), the Accessory Protocol Interface Module
(APIM) and the Instrument Cluster (IC) all communicate on the MS-CAN.
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
-
ACM
-
APIM
-
DSM
-
RETM
