Explorer AWD V8-4.6L (2010)
Yes
CONNECT the negative battery cable. GO to S49.
No
REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
S9 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR A SHORT TOGETHER
-
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
GO to S11.
No
GO to S10.
-------------------------------------------------
S10 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR AN OPEN
-
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 greater than 10,000 ohms?
Yes
REPAIR the DLC or REPAIR the circuit in question. CONNECT the negative battery cable. VERIFY the scan tool operation on a substitute vehicle.
CLEAR the DTCs. REPEAT the network test on the suspect vehicle.
No
A capacitor internal to a module may still be draining causing irregular resistance readings. WAIT 5 minutes. REPEAT the pinpoint test.
-------------------------------------------------
S11 CHECK THE MS-CAN (+) AND MS-CAN (-) CIRCUITS FOR A SHORT TOGETHER WITH THE IC DISCONNECTED
-
Disconnect: IC C220.
-
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.
