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 following modules communicate on the HS-CAN:
-
PCM
-
Power steering control module
-
ABS module
-
Restraints control module (RCM)
-
Four-wheel drive (4WD) control module
-
Instrument cluster
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
