Inspection and Verification

WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify the customer concern.
  2. Visually inspect for obvious signs of mechanical or electrical damage.
    VISUAL INSPECTION CHART

    Mechanical Electrical
    • Axle shafts and CV joints
    • Battery junction box (BJB) fuse:
      • 18 (20A)
    • Driveshaft and universal joints
    • Central junction box (CJB) fuse:
      • 24 (15A)
     
    • Fluid leaks
     
    • Matching tire sizes
     
    • 4x4 module (PCM)
     
    • Wiring harness
     
    • Connector(s)
     
    • Circuitry
  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 concern 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 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:
    • CAN circuit fault; all electronic control units no response/not equipped, refer to MODULE COMMUNICATIONS NETWORK .
    • No response/not equipped for 4WD module (PCM), GO to PINPOINT TEST A .
    • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out the 4WD module (PCM) self-test.
  7. If the DTCs retrieved are related to the concern, go to the 4WD CONTROL MODULE (PCM) DIAGNOSTIC TROUBLE CODE (DTC) INDEX  to continue diagnostics.
