Mountaineer AWD V6-4.0L (2008)
P45-P46
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.
