WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. 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 CHART
Mechanical Electrical - Front display interface module (FDIM)
- Front controls interface module (FCIM)
- Antenna (AM/FM or satellite radio)
- Speaker mounting/speaker cones
- Trim panels
- Navigation DVD
- Noise suppression equipment
- Smart junction box (SJB) fuse(s):
- 14 (10A) (FCIM, FDIM, and satellite digital audio receiver system [SDARS] module)
- 38 (20A) (subwoofer)
- 39 (20A) (audio control module [ACM])
- Wiring, terminals or connectors
- If the fault is visually evident, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, connect the scan tool to the data link connector (DLC).
- 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 article, No Power To The Scan Tool, to diagnose no communication with 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 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 article.
- If the network test passes, retrieve and record the continuous memory DTCs.
- Clear the continuous DTCs and carry out the self-test diagnostics for the ACM, FDIM, FCIM, and SDARS module (if equipped).
- If the DTCs retrieved are related to the concern, go to DTC ChartsΒ .
- If no DTCs related to the concern are retrieved, go to the Speaker Walk-Around Test, the Audio Control Module (ACM) Self-Diagnostic Mode, the Navigation Audio Control Module (ACM) Self-Diagnostics, or the Satellite Audio Bezel Diagnostic Test, as appropriate.
NOTE:
Make sure to use the latest scan tool software release.
NOTE:
The vehicle communication module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM.
NOTE:
Do not press any buttons on the FCIM while the ACM is carrying out the self-test.
