Pinpoint Test 16: No High Speed Controller Area Network (HS-CAN) Communication, All Modules Are Not Responding

PINPOINT TEST 16: NO HIGH SPEED CONTROLLER AREA NETWORK (HS-CAN) COMMUNICATION, ALL MODULES ARE NOT RESPONDING

Normal Operation

The High-Speed Controller Area Network (HS-CAN) uses an unshielded twisted pair cable, circuits (W/BL) and (W).

Possible Causes
- Fuse
- Wiring, terminals or connectors
- 4X4 control module (if equipped)
- ABS module
- Instrument Cluster (IC)
- Occupant Classification System Module (OCSM)
- PCM
- Power Steering Control Module (PSCM)
- Restraints Control Module (RCM)

Diagnostic Procedure

CAUTION:Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE:Failure to disconnect the battery when instructed will result in false resistance readings. See Battery Disconnect.
