Test S: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, One Or
More Modules Are Not Responding Durin
PINPOINT TEST S: INTERMITTENT NO HIGH SPEED CONTROLLER AREA NETWORK (HS-CAN) COMMUNICATION, ONE OR
MORE MODULES ARE NOT RESPONDING DURING NETWORK TEST
Normal Operation
An open circuit VDB04 (WH/BU) (HS-CAN +) or VDB05 (WH) (HS-CAN -) may cause intermittent or unreliable communication to all modules on
the HS-CAN. The HS-CAN is used for communication between the following modules:
-
ABS module
-
Instrument cluster (IC)
-
Occupant classification system module (OCSM)
-
PCM
-
Restraints control module (RCM)
-
Transmission control module (TCM) (6R60 transmission only)
-
4X4 control module (if equipped)
In the event that one of the 2 network circuits (HS-CAN + or HS-CAN -) becomes open to a module on the network, unreliable network
communication to all modules on the network may result.
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
