Normal Operation
The medium speed controller area network (MS-CAN) uses an unshielded twisted pair cable, circuits VDB06 (GY/OG) and VDB07 (VT/OG) provide
the network connection to all modules on the network. The smart junction box (SJB), the instrument cluster (IC), the heating ventilation air
conditioning (HVAC) module (if equipped), the audio control module (ACM), the satellite digital audio receiver system (SDARS) module (if
equipped), the rear entertainment module (RETM) (if equipped), the power running board (PRB) module (if equipped), the parking aid module
(PAM) (if equipped), and the driver seat module (DSM) all communicate with the scan tool using the MS-CAN.
This pinpoint test is intended to diagnose the following:
