Inspection and Verification

WARNING: This page is about a different car, the 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify the customer concern by checking the air bag indicator in the instrument cluster. For additional information, refer to PROVE OUT THE SYSTEM .
  2. Visually inspect for obvious signs of mechanical and electrical damage using the following chart.
    VISUAL INSPECTION CHART

    Mechanical Electrical
    • Damaged restraints control module (RCM) or loose mounting
    • Damaged front impact severity sensor or loose mounting
    • Damaged side impact sensor or loose mounting
    • Open central junction box (CJB) fuse 26 (10A)
    • Damaged wiring harness
    • Loose, damaged or corroded connectors
    • Circuitry open/shorted
    • Damaged shorting bars
  3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
  4. If the cause is not visually evident, connect the diagnostic tool to the data link connector and select the vehicle to be tested from the diagnostic tool menu.

    If the diagnostic tool does not communicate with the vehicle:

    • Check that the program card is correctly installed.
    • Check that the latest diagnostic tool software release is being used.
    • Check the connections to the vehicle.
    • Check the ignition switch position.
  5. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
  6. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
    • ISO circuit fault; all electronic control units no response/not equipped, refer to MODULE COMMUNICATIONS NETWORK .
    • No response/not equipped for restraints control module (RCM), Go to SYMPTOM CHART .
    • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs) and carry out the on demand self test diagnostics for the RCM.
  7. If the DTCs retrieved are related to the concern, go to the RESTRAINTS CONTROL MODULE (RCM) DIAGNOSTIC TROUBLE CODE (DTC) TABLE .
  8. If no DTCs related to the concern are retrieved, Go to SYMPTOM CHART .
