Test J: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, One Or
More Modules Are Not Responding Durin
PINPOINT TEST J: INTERMITTENT NO HIGH SPEED CONTROLLER AREA NETWORK (HS-CAN) COMMUNICATION, ONE OR
MORE MODULES ARE NOT RESPONDING DURING NETWORK TEST
Normal Operation
The HS-CAN is used for communication between the PCM, the ABS module and the instrument cluster (IC). 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.
In the event that either circuit VDB04 (WH/BU) (HS-CAN +) or VDB05 (WH) (HS-CAN -) 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
