Explorer Sport Trac 2WD V6-4.0L (2009)
-
Is the resistance between 54 and 66 ohms?
Yes
GO to G2.
No
GO to G4.
-------------------------------------------------
G2 CHECK THE IC GROUND CIRCUIT FOR AN OPEN
-
Measure the resistance between the IC C220-13, circuit GD145 (BK/BU), harness side and ground.
-
Is the resistance less than 5 ohms?
Yes
CONNECT the negative battery cable. GO to G3.
No
REPAIR the circuit. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
G3 CHECK THE IC VOLTAGE SUPPLY CIRCUITS FOR AN OPEN
-
Disconnect: IC C220.
-
Ignition ON.
-
Measure the voltage between the IC, harness side and ground as follows:
-
Are the voltages greater than 10 volts?
Yes
GO to G5.
No
VERIFY the Smart Junction Box (SJB) fuse 8 (15A) or fuse 24 (10A) is OK. If OK, REPAIR the circuit in question. If not OK, REFER to the Wiring
Diagrams to identify the possible causes of the circuit short. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
G4 CHECK THE HS-CAN CIRCUITS BETWEEN THE IC AND THE DLC FOR AN OPEN
-
Measure the resistance between the IC C220-7, circuit VDB04 (WH/BU), harness side and the DLC C251-6, circuit VDB04 (WH/BU), harness
side.
