PINPOINT TEST M: 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 is optional equipment. The SDARS module communicates with the scan tool through the
medium speed controller area network (MS-CAN). Circuits VDB06 (GY/OG) (MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network
connection to the SDARS module. The SDARS module shares the MS-CAN network with the instrument cluster, smart junction box (SJB), electronic
automatic temperature control (EATC) or electronic manual temperature control (EMTC) module, audio control module (ACM), SDARS module and
DVD player (if equipped). Voltage to the EATC/EMTC module is provided by circuit SBP40 (VT/RD). Ground is provided by circuit GD114
(BK/BU).
This pinpoint test is intended to diagnose the following:
-
