Milan FWD V6-3.0L (2010)
-------------------------------------------------
AD18 CHECK FOR RESTORED NETWORK COMMUNICATION WITH THE RCM DISABLED
-
Disconnect: SJB Fuse 32 (10A) .
-
Enter the following diagnostic mode on the scan tool: Network Test .
-
Repeat the network test.
-
Do all other HS-CAN modules pass the network test?
Yes
INSTALL the removed fuse. GO to Pinpoint Test E. See: Pinpoint Test E: The Restraints Control Module (RCM) Does Not Respond To The Scan Tool
No
INSTALL the removed fuse. An intermittent fault is not present. GO to Pinpoint Test AC. See: Pinpoint Test AC: No Medium Speed CAN (MS-CAN)
Communication, All Modules Are Not Responding

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
-
4X4 control module (if equipped)
-
ABS module
-
Accessory Protocol Interface Module (APIM) (if equipped)
-
Air Conditioning Compressor Module (ACCM) (Hybrid only)
-
Battery Energy Control Module (BECM) (Hybrid only)
-
DC to DC Converter Control Module (DC/DC) (Hybrid only)
-
Headlamp Control Module (HCM) (if equipped)
-
Instrument Panel Cluster (IPC) (gateway module)
-
Occupant Classification System Module (OCSM)
-
PCM
-
Power Steering Control Module (PSCM) (if equipped)
-
Restraints Control Module (RCM)
-
Transmission Control Module (TCM) (if equipped)
PINPOINT TEST AE: NO HS-CAN COMMUNICATION, ALL MODULES ARE NOT RESPONDING
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint
test. See: Initial Inspection and Diagnostic Overview/Communications Network/Inspection and Verification
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
