Test Q: No High Speed Controller Area Network (HS-CAN) Communication, All Modules Are Not Responding

PINPOINT TEST Q: NO HIGH SPEED CONTROLLER AREA NETWORK (HS-CAN) COMMUNICATION, ALL MODULES ARE NOT RESPONDING

Normal Operation
Circuits VDB04 (WH/BU) (HS-CAN +) and VDB05 (WH) (HS-CAN -) provide the HS-CAN network connection. The HS-CAN network is used for network communication between the PCM, the power steering control module, the ABS module, the restraints control module (RCM), the four-wheel drive (4WD) control module and the instrument cluster.

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- ABS module
- 4WD control module
- Instrument cluster
- Occupant classification sensor (OCS) module
- PCM
- RCM
- Power steering control module
