Normal Operation
The 4X4 control module communicates with the scan tool through the High Speed Controller Area Network (HS-CAN). Circuits VDB04 (WH/BU)
(HS-CAN +) and VDB05 (WH) (HS-CAN -) provide the network connection to the 4X4 control module. Voltage is supplied by circuits CBP18
(GY/OG), SBB23 (RD/WH) and SBB26 (RD/BK). Ground is supplied by circuits GD138 (BK/WH) and GD145 (BK/BU).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
