PINPOINT TEST J: THE AUDIO CONTROL MODULE (ACM) DOES NOT RESPOND TO THE SCAN TOOL
Normal Operation
Circuits VDB06 (GY/OG) (MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the audio control module (ACM). The
ACM shares the MS-CAN with the instrument cluster (IC), the smart junction box (SJB), the heating ventilation air conditioning (HVAC) module (if
equipped), the satellite digital audio receiver system (SDARS) module (if equipped), the rear entertainment module (RETM), the driver seat module
(DSM) (if equipped), the power running board (PRB) module (if equipped) and the parking aid module (PAM) (if equipped). Voltage for the ACM is
provided by circuits CBP12 (GN/WH) and SBP03 (BU/RD). Circuit GD114 (BK/BU) provides ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
ACM
