Explorer Sport Trac 2WD V6-4.0L (2009)
PINPOINT TEST L: THE RETM DOES NOT RESPOND TO THE SCAN TOOL
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
-------------------------------------------------
L1 CHECK THE RETM VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: RETM C9029.
-
Ignition ON.
-
Measure the voltage between the RETM C9029-16, circuit SBB41 (RD), harness side and ground.
-
Is the voltage greater than 10 volts?
Yes
GO to L2.
No
VERIFY the Battery Junction Box (BJB) fuse 41 (15A) is OK. If OK, REPAIR the circuit. 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.
-------------------------------------------------
L2 CHECK THE RETM GROUND CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the RETM C9029-1, circuit GD114 (BK/BU), harness side and ground.
-
Is the resistance less than 5 ohms?
Yes
GO to L3.
No
REPAIR the circuit. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
L3 CHECK THE MS-CAN CIRCUITS BETWEEN THE RETM AND THE DLC FOR AN OPEN
-
Measure the resistance between the RETM C9029-8, circuit VDB06 (GY/OG), harness side and the DLC C251-3, circuit VDB06 (GY/OG),
harness side.
