Edge AWD V6-3.5L (2009)
-
Ignition OFF.
-
Disconnect: LTM C4174a.
-
Ignition ON.
-
Measure the voltage between the LTM C4174a-4, circuit SBB59 (BU/RD), harness side and ground; and between the LTM C4174a-9, circuit
SBP14 (BN/RD), harness side and ground.
-
Are the voltages greater than 10 volts?
Yes
GO to N2.
No
VERIFY the Battery Junction Box (BJB) fuse 59 (30A) or the SJB fuse 14 (10A) 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.
-------------------------------------------------
N2 CHECK THE LTM GROUND CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the LTM C4174a-1, circuit GD149 (BK/GY), harness side and ground.
-
Is the resistance less than 5 ohms?
Yes
GO to N3.
No
REPAIR the circuit. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
N3 CHECK THE MS-CAN CIRCUITS BETWEEN THE LTM AND THE DLC FOR AN OPEN
-
Disconnect: LTM C4174b.
-
Measure the resistance between the LTM C4174b-11, circuit VDB06 (GY/OG), harness side and the DLC C251-3, circuit VDB06 (GY/OG),
harness side.
