Test G: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, One Or
More Modules Are Not Responding Durin
PINPOINT TEST G: INTERMITTENT NO HIGH SPEED CONTROLLER AREA NETWORK (HS-CAN) COMMUNICATION, ONE OR
MORE MODULES ARE NOT RESPONDING DURING THE NETWORK TEST
Normal Operation
An open in circuit VDB04 (WH/BU) (HS-CAN +) or VDB05 (WH) (HS-CAN -) may cause intermittent or unreliable communication to all modules
on the high speed controller area network (HS-CAN). The HS-CAN is used for communication between the following modules:
-
ABS module
-
Instrument cluster (IC)
-
PCM
-
Restraints control module (RCM)
In the event that either circuit VDB04 (WH/BU) or VDB05 (WH) becomes open to any 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
