Explorer AWD V8-4.6L (2010)
-
Ignition ON.
-
Measure the voltage between the TCM C1575-9, circuit CE517 (BU/GN), harness side and ground; and between the TCM C1575-14, circuit
SBB27 (BU/RD), harness side and ground.
-
Are the voltages greater than 10 volts?
Yes
GO to B2.
No
VERIFY the Battery Junction Box (BJB) fuse 27 (20A) or Smart Junction Box (SJB) fuse 9 (2A) 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.

B2 CHECK THE TCM GROUND CIRCUITS FOR AN OPEN
-
Ignition OFF.
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the TCM C1575-13, circuit GD113 (BK/YE), harness side and ground; and between the TCM C1575-16, circuit
GD113 (BK/YE), harness side and ground.
-
Are the resistances less than 5 ohms?
Yes
GO to B3.
No
REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.

B3 CHECK THE HS-CAN CIRCUITS BETWEEN THE TCM AND THE DLC FOR AN OPEN
-
Measure the resistance between the TCM C1575-6, circuit VDB04 (WH/BU), harness side and the DLC C251-6, circuit VDB04 (WH/BU),
harness side.
