Flex AWD V6-3.5L (2009)
VERIFY the Battery Junction Box (BJB) fuse 7 (30A) 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.
-------------------------------------------------
L2 CHECK THE AUDIO DSP MODULE GROUND CIRCUITS FOR AN OPEN
-
Ignition OFF.
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the audio DSP module, harness side and ground as follows:
-
Are the resistances 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 AUDIO DSP MODULE AND THE DLC FOR AN OPEN
-
Disconnect: Audio DSP Module C4208a.
-
Measure the resistance between the audio DSP module C4208a-1, circuit VDB06 (GY/OG), harness side and the Data Link Connector (DLC)
C251-3, circuit VDB06 (GY/OG), harness side.
-
Measure the resistance between the audio DSP module C4208a-11, circuit VDB07 (VT/OG), harness side and the DLC C251-11, circuit VDB07
(VT/OG), harness side.
