Flex AWD V6-3.5L (2009)
CONNECT the negative battery cable. GO to H4.
No
REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
H4 CHECK FOR CORRECT LTM OPERATION
-
Disconnect the LTM connector.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect the LTM connector and make sure it seats correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new LTM. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the
network test with the scan tool.

Pinpoint Test I: The Smart Junction Box (SJB) Does Not Respond To The Scan Tool
Refer to Wiring Diagram Set 10, Grounds for schematic and connector information. See: Diagrams/Electrical Diagrams/Diagrams By Number
Refer to Wiring Diagram Set 13, Power Distribution/SJB for schematic and connector information. See: Diagrams/Electrical Diagrams/Diagrams By

Normal Operation
The Smart Junction Box (SJB) communicates with the scan tool through the Medium Speed Controller Area Network (MS-CAN). Circuits VDB06
(GY/OG) (MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the SJB. Voltage for the SJB is provided by an internal
SJB busbar to SJB fuse 5 (10A). Circuit GD133 (BK) provides ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
SJB
PINPOINT TEST I: THE SJB 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.
