Test X: Intermittent No Medium Speed Controller Area Network (MS-CAN) Communication, One Or More Modules Are Not Responding Dur
PINPOINT TEST X: 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 cable pair. Circuits VDB06 (GY/OG) and VDB07 (VT/OG) provide the network connection to all modules on the network. The smart junction box (SJB), the instrument cluster (IC), the heating ventilation air conditioning (HVAC) module - electronic manual temperature control (EMTC) (if equipped), the heating ventilation air conditioning (HVAC) module - electronic automatic temperature control (EATC) (if equipped), the audio control module (ACM), the audio digital signal processing (DSP) module (if equipped), the satellite digital audio receiver system (SDARS) module (if equipped), the audio rear control unit (RCU) (if equipped), the rear entertainment module (RETM) (if equipped), the power running board (PRB) module (if equipped), the parking aid module (PAM) (if equipped), the liftgate/trunk module (LTM) (if equipped), the driver seat module (if equipped), and the dual climate control seat module (DCSM) (if equipped) all communicate with the scan tool using the MS-CAN.
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
