Inspection and Verification

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

Verify the customer concern.

Visually inspect for obvious signs of mechanical or electrical damage.

VISUAL INSPECTION TABLE

Mechanical	Electrical
Multifunction switch	Smart Junction Box (SJB) fuse 27 (20A)
Ignition key Ignition lock cylinder Ignition switch Steering column lock module Steering column shrouds	Wiring, terminals or connectors Ignition switch One-Touch Integrated Start (OTIS) diode SJB PCM Park range switch (part of the selector lever)

If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

NOTE: Make sure to use the latest scan tool software release.

If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).

NOTE: The Vehicle Communication Module (VCM) LED prove out confirms power and ground from the DLC are provided to the VCM.

If the scan tool does not communicate with the VCM:
- check the VCM connection to the vehicle.
- check the scan tool connection to the VCM.
- refer to MODULE COMMUNICATIONS NETWORK -- FUSION, MILAN & MKZ article, No Power To The Scan Tool, to diagnose no power to the scan tool.
If the scan tool does not communicate with the vehicle:
- verify the ignition key is in the ON position.
- verify the scan tool operation with a known good vehicle.
- refer to MODULE COMMUNICATIONS NETWORK -- FUSION, MILAN & MKZ article to diagnose no response from the PCM.
Carry out the network test.
- If the scan tool responds with no communication for one or more modules, refer to MODULE COMMUNICATIONS NETWORK -- FUSION, MILAN & MKZ article.
- If the network test passes, retrieve and record Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Clear the continuous DTCs and carry out the self-test diagnostics for the SJB.
If the DTCs retrieved are related to the concern, go to SMART JUNCTION BOX (SJB) DTC TABLE . For all other DTCs, refer to MULTIFUNCTION ELECTRONIC MODULES -- FUSION, MILAN & MKZ article.
If no DTCs related to the concern are retrieved, GO to SYMPTOM TABLE .
