Flex FWD V6-3.5L (2010)
-
Smart Junction Box (SJB)
PINPOINT TEST X: 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
test. See: Initial Inspection and Diagnostic Overview/Module Communications Network/Inspection and Verification
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.

X26 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR A SHORT TO GROUND WITH THE GPSM DISCONNECTED
-
Disconnect: GPSM C2300.
-
Measure the resistance between the DLC C251-3, circuit VDB06 (GY/OG), harness side and ground; and between the DLC C251-11, circuit
VDB07 (VT/OG), harness side and ground.
-
Are the resistances greater than 1,000 ohms?
Yes
CONNECT the negative battery cable. GO to X40.
No
GO to X27.
