Test F: The Satellite Digital Audio Receiver System (SDARS) Module Does Not Respond To The Scan Tool

PINPOINT TEST F: THE SATELLITE DIGITAL AUDIO RECEIVER SYSTEM (SDARS) MODULE DOES NOT RESPOND TO THE SCAN TOOL

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 1847 (WH/OG) (MS-CAN +) and 1848 (PK/OG) (MS-CAN -) provide the network connection to the SDARS module. The SDARS module shares the MS-CAN with the smart junction box (SJB), the audio control module (ACM) and the instrument cluster (IC). Voltage for the SDARS module is provided by circuit 729 (RD/WH). Ground is provided by circuit 1204 (BK/OG).

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals and connectors
- SDARS module
