PINPOINT TEST R: NO HIGH SPEED CONTROLLER AREA NETWORK (HS-CAN) COMMUNICATION, ALL MODULES ARE NOT
RESPONDING
Normal Operation
The high speed controller area network (HS-CAN) uses an unshielded twisted pair cable, circuits VDB04 (WH/BU) and VDB05 (WH). The PCM, the
transmission control module (TCM), the ABS module, the restraints control module (RCM), the 4X4 control module (if equipped), the occupant
classification system module (OCSM) and the instrument cluster (IC) all communicate with the scan tool using the HS-CAN.
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
-
PCM
-
RCM
-
ABS module
-
IC
-
TCM (if equipped)
-
4X4 control module (if equipped)
