PINPOINT TEST 13: THE SATELLITE DIGITAL AUDIO RECEIVER SYSTEM (SDARS) DOES NOT RESPOND TO THE SCAN TOOL - HYBRID

Normal Operation

The satellite digital audio receiver system (SDARS) module communicates with the scan tool through the medium speed controller area network (MS-CAN). Circuits (GY/O) (MS-CAN +) and (V/O) (MS-CAN -) provide the network connection to the SDARS module. The SDARS module shares the MS-CAN network with the instrument cluster, dual automatic temperature control (DATC) module, smart junction box (SJB), audio control module (ACM), front controls interface module (FCIM) and front display interface module (FDIM). Voltage to the SDARS module is provided by circuit (BR/R). Ground is provided by circuit (B/GY).

Possible Causes
- Fuse
- Wiring, terminals or connectors
- SDARS module

Diagnostic Procedure
