Test M: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, One Or More Modules Are Not Responding Durin

PINPOINT TEST M: INTERMITTENT NO HIGH SPEED CONTROLLER AREA NETWORK (HS-CAN) COMMUNICATION, ONE OR MORE MODULES ARE NOT RESPONDING DURING THE NETWORK TEST

Normal Operation
An open in circuit 1827 (WH/LG) (HS-CAN +) or 1828 (PK/LG) (HS-CAN -) may cause intermittent or unreliable communication to all modules on the HS-CAN. The HS-CAN is used for communication between the following modules:
- ABS module
- Vehicle dynamics module (VDM)
- Instrument cluster (IC)
- PCM

In the event that either circuit 1827 (WH/LG) or 1828 (PK/LG) 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
