Fusion FWD V6-3.0L (2009)
-
Measure the resistance between the PCM C175b-3, circuit VDB05 (WH), harness side and the DLC C251-14, circuit VDB05 (WH), harness side.
-
Are the resistances less than 5 ohms?
Yes
The Controller Area Network (CAN) has tested within specifications. CONNECT the negative battery cable. VERIFY the scan tool operation on a
substitute vehicle, and REPEAT the network test on the suspect vehicle.
No
REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
