-
Disconnect: SJB C2280d.
-
Measure the resistance between the DLC C251-3, circuit VDB06 (GY/OG), harness side and the DLC C251-11, circuit VDB07 (VT/OG), harness
side.
-
Is the resistance less than 5 ohms?
Yes
REPAIR the circuit. CONNECT all modules. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.

Pinpoint Test Q: No Medium Speed Controller Area Network (MS-CAN) Communication, All Modules Are Not Responding
Refer to Wiring Diagram Set 14, Module Communications Network for schematic and connector information. See: Diagrams/Electrical
Diagrams/Diagrams By Number
Normal Operation
The Medium Speed Controller Area Network (MS-CAN) uses an unshielded twisted pair cable, circuits VDB06 (GY/OG) and VDB07 (VT/OG) provide
the network connection to all modules on the network.
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
-
Accessory Protocol Interface Module (APIM) (if equipped)
-
Audio Control Module (ACM)
-
Driver Seat Module (DSM) (if equipped)
-
HVAC module (if equipped)
-
Instrument Cluster (IC)
-
Parking Aid Module (PAM) (if equipped)
-
Power Running Board (PRB) module (if equipped)
-
Rear Entertainment Module (RETM) (if equipped)
-
Satellite Digital Audio Receiver System (SDARS) module (if equipped)
-
Smart Junction Box (SJB)
PINPOINT TEST Q: NO MS-CAN COMMUNICATION, ALL MODULES ARE NOT RESPONDING
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint
