Lost Communication with Body Control Module (SJB)

Description

The Smart Junction Box (SJB) communicates with the scan tool through the medium speed controller area network (MS-CAN).

The SJB shares the MS-CAN with the Instrument Cluster (IC), HVAC module, audio control module (ACM), satellite digital audio receiver system (SDARS) module, Front Controls Interface Module (FCIM) and Front Display Interface Module (FDIM). Voltage for the SJB is provided directly from the internal SJB busbar through SJB fuse 5 (10A). Ground is provided by circuit (B GY).
