WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. 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 electrical damage.VISUAL INSPECTION CHART
Electrical - Central junction box (CJB) fuse(s):
- 12 (15A)
- 6 (10A)
- Wiring, terminals or connectors
- Parking aid module (PAM)
- Parking aid sensors
- Parking aid disable switch
- Parking aid disable switch indicator
- Parking aid speaker
- Reversing lamps
- Central junction box (CJB) fuse(s):
- If an obvious cause for an observed or reported concern is found, 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 PAM.
- If the DTCs retrieved are related to the concern, go to DTC Charts. For all other DTCs, refer to MULTIFUNCTION ELECTRONIC MODULES article.
- If no DTCs related to the concern are retrieved, go to Symptom Chart .
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:
Follow the non-network DTC diagnostics (B-codes, C-codes, P-codes) prior to the network DTC diagnostics (U-codes).
