Mariner 4WD V6-3.0L (2010)
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.
-------------------------------------------------
O1 CHECK THE FCIM VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: FCIM C2402 .
-
Ignition ON.
-
Measure the voltage between the FCIM C2402-1, circuit SBP14 (BN/RD), harness side and ground.
-
Is the voltage greater than 10 volts?
Yes
GO to O2.
No
VERIFY the Smart Junction Box (SJB) fuse 14 (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. See: Diagrams/Electrical Diagrams/Diagrams
By Number
-------------------------------------------------
O2 CHECK THE FCIM GROUND CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: Negative Battery Cable .
-
Measure the resistance between the FCIM C2402-2, circuit GD115 (BK/GY), harness side and ground.
-
Is the resistance less than 5 ohms?
Yes
GO to O3.
No
REPAIR the circuit. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
O3 CHECK THE MS-CAN CIRCUITS BETWEEN THE FCIM AND THE DLC FOR AN OPEN
-
Measure the resistance between the FCIM C2402-3, circuit VDB06 (GY/OG), harness side and the Data Link Connector (DLC) C251-3, circuit
VDB06 (GY/OG), harness side.
