Refer to Wiring Diagram Set 123, Memory Seats for schematic and connector information. See: Diagrams/Electrical Diagrams/Diagrams By Number
Normal Operation
The Driver Seat Module (DSM) 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 DSM. Voltage for the DSM is provided by circuits
CBX03 (BU/RD) and CBX05 (VT/RD). Circuits GD905 (BK/GN) and GD906 (BK/GY) provide ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
DSM
