Milan FWD L4-2.5L (2010)
-
Disconnect: Battery Energy Control Module (BECM) C4237a .
-
Measure the resistance between the DLC C251-6, circuit VDB04 (WH/BU), harness side and the DLC C251-14, circuit VDB05 (WH), harness
side.
-
Is the resistance less than 5 ohms?
Yes
GO to AE27.
No
CONNECT the negative battery cable. GO to AE53.
-------------------------------------------------
AE27 CHECK THE HS-CAN (+) AND HS-CAN (-) CIRCUITS FOR A SHORT TOGETHER WITH THE DC/DC DISCONNECTED
-
Disconnect: DC/DC C1457d .
-
Measure the resistance between the DLC C251-6, circuit VDB04 (WH/BU), harness side and the DLC C251-14, circuit VDB05 (WH), harness
side.
-
Is the resistance less than 5 ohms?
Yes
REPAIR the circuits. CONNECT all modules. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
CONNECT the negative battery cable. GO to AE54.

Communications Network
Pinpoint Tests
Pinpoint Test AE: No High Speed Controller Area Network (HS-CAN) Communication, All Modules Are Not Responding
Refer to Wiring Diagram Set 14 (Fusion/Milan/MKZ, Fusion Hybrid/Milan Hybrid), Module Communications Network for schematic and connector
information. See: Diagrams/Electrical Diagrams/Diagrams By Number
Normal Operation
The High Speed Controller Area Network (HS-CAN) uses an unshielded twisted pair cable, circuits VDB04 (WH/BU) and VDB05 (WH).
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
