Test S: Intermittent No Medium Speed Controller Area Network (MS-CAN) Communication, One Or
More Modules Are Not Responding Dur
PINPOINT TEST S: INTERMITTENT NO MEDIUM SPEED CONTROLLER AREA NETWORK (MS-CAN) COMMUNICATION, ONE
OR MORE MODULES ARE NOT RESPONDING DURING NETWORK TEST
Normal 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:
-
Accessory protocol interface module (APIM) (if equipped)
-
Audio control module (ACM)
-
Audio digital signal processing (DSP) module (if equipped)
-
Driver seat module (DSM) (if equipped)
-
Driver door module (DDM) (if equipped)
-
Dual climate control seat module (DCSM) (if equipped)
-
Heating ventilation air conditioning (HVAC) module (if equipped)
-
Instrument cluster (IC)
-
Parking aid module (PAM) (if equipped)
-
Satellite digital audio receiver system (SDARS) module (if equipped)
-
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
