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

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

Normal Operation
The HS-CAN uses an unshielded twisted pair cable, circuits 1827 (WH/LG) and 1828 (PK/LG). The PCM, the ABS module (if equipped) and the instrument cluster (IC) all communicate with the scan tool using the HS-CAN.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals and connectors
- ABS module (if equipped)
- IC
- PCM
