Fusion FWD V6-3.0L (2009)
-
Is the voltage greater than 10 volts?
Yes
GO to N2.
No
VERIFY the Smart Junction Box (SJB) fuse 20 (7.5A) is OK. If OK, REPAIR the circuit. CLEAR the DTCs. REPEAT the network test with the scan
tool. If not OK, REFER to the Wiring Diagrams to identify the possible cause of the circuit short.
-------------------------------------------------
N2 CHECK THE DDM GROUND CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the DDM C568b-12, circuit GD126 (BK/WH), harness side and ground.
-
Is the resistance less than 5 ohms?
Yes
GO to N3.
No
REPAIR the circuit. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
N3 CHECK THE MS-CAN CIRCUITS BETWEEN THE DDM AND THE DLC FOR AN OPEN
-
Measure the resistance between the DDM C568a-12, circuit VDB06 (GY/OG), harness side and the Data Link Connector (DLC) C251-3, circuit
VDB06 (GY/OG), harness side.
-
Measure the resistance between the DDM C568a-6, circuit VDB07 (VT/OG), harness side and the DLC C251-11, circuit VDB07 (VT/OG),
harness side.
