Test H: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, One Or More Modules Are Not Responding Durin
PINPOINT TEST H: INTERMITTENT NO HIGH SPEED CONTROLLER AREA NETWORK (HS-CAN) COMMUNICATION, ONE OR MORE MODULES ARE NOT RESPONDING DURING NETWORK TESTNormal Operation
The HS-CAN network is used for communication between the PCM, the power steering control module (PSCM), the ABS module, the restraints control module (RCM), the 4X4 control module (if equipped) 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 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
