Test T: Intermittent No Medium Speed Controller Area Network (MS-CAN) Communication, One Or More Modules Are Not Responding Dur
PINPOINT TEST T: INTERMITTENT NO MEDIUM SPEED CONTROLLER AREA NETWORK (MS-CAN) COMMUNICATION, ONE OR MORE MODULES ARE NOT RESPONDING DURING NETWORK TESTNormal Operation
The MS-CAN uses an unshielded twisted pair cable, circuits VDB06 (GY/OG) and VDB07 (VT/OG). The following modules communicate on the MS-CAN:
- Audio unit
- Digital versatile disc (DVD) player
- Driver seat module (DSM)
- Electronic automatic temperature control (EATC) or electronic manual temperature control (EMTC) module
- Instrument cluster
- Power liftgate module
- Satellite radio receiver
- Smart junction box (SJB)
In the event that one of the 2 network circuits (HS-CAN + or HS-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
