Inspection and Verification

WARNING: This page is about a different car, the 2005 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: When servicing the starter motor or carrying out other underhood work in the vicinity of the starter motor, be aware that the heavy gauge battery input lead at the starter solenoid is "electrically hot" at all times. A protective cap or boot is provided over the terminal of this lead and must be installed after servicing. Failure to follow these instructions may result in personal injury.
WARNING: When working in the area of the starter motor, be careful to avoid touching hot exhaust components. Failure to follow these instructions may result in personal injury.
NOTE: When working on the starter system, make sure the anti-theft system is deactivated, if equipped.
  1. Verify the customer concern by operating the starting system.
  2. Visually inspect for obvious signs of mechanical and electrical damage. Refer to the following chart VISUAL INSPECTION CHART :
    VISUAL INSPECTION CHART

    Mechanical Electrical
    • Starter motor
    • Brackets
    • Battery
    • Smart junction box (SJB) fuse:

  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 (DLC) 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:
    • [appropriate communication networks, such as SCP, ISO, UBP, CAN] circuit fault; all electronic control units no response/not equipped, refer to MODULE COMMUNICATIONS NETWORK .
    • No response/not equipped for generic electronic module (GEM), refer to MULTIFUNCTION ELECTRONIC MODULES .
    • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out the self-test diagnostics for the GEM.
  7. If the DTCs retrieved are related to the concern, go to the PASSIVE ANTI-THEFT SYSTEM (PATS) - DIAGNOSTIC TROUBLE CODE (DTC) INDEX .
  8. If no DTCs related to the concern are retrieved, GO to SYMPTOM CHART .
