Test Q: Intermittent No Medium Speed Controller Area Network (MS-CAN) Communication, One Or More Modules Are Not Responding Dur

PINPOINT TEST Q: INTERMITTENT NO MEDIUM SPEED CONTROLLER AREA NETWORK (MS-CAN) COMMUNICATION, ONE OR MORE MODULES ARE NOT RESPONDING DURING NETWORK TEST

Normal Operation
An open circuit VDB06 (GY/OG) (MS-CAN +) or VDB07 (VT/OG) (MS-CAN -) may cause intermittent or unreliable communication to all modules on the high speed controller area network (HS-CAN). The HS-CAN is used for communication between the following modules:

- Audio control module (ACM)
- Rear entertainment module (RETM)
- Driver seat module (DSM)
- Heating ventilation air conditioning (HVAC) module
- Instrument cluster (IC)
- Parking aid module (PAM)
- Power running board (PRB) module
- Satellite digital audio receiver system (SDARS) module
- Smart junction box (SJB)

In the event that one of the 2 network circuits (MS-CAN + or MS-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.
