Pinpoint Test B: A Chime Is Inoperative-Key-In-Ignition (With The Door Ajar)

WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. B1 CARRY OUT THE INSTRUMENT CLUSTER WARNING LAMPS AND CHIME ACTIVE COMMAND USING THE DIAGNOSTIC TOOL 
    • Key in ON position.
    • Enter the following diagnostic mode on the diagnostic tool: Instrument Cluster Active Command.
    • Select the instrument cluster warning lamps and chime active command. Trigger the all lamps and chime active command on.
    • Does the chime sound? 
    • Yes  : GO to B2.
    • No  : GO to  B6.
  2. B2 MONITOR THE INSTRUMENT CLUSTER KEY-IN-IGNITION PID 
    • Enter the following diagnostic mode on the diagnostic tool: Instrument Cluster Key-In-Ignition PID.
    • Monitor the instrument cluster key-in-ignition PID while inserting and removing the key from the ignition switch.
    • Do the PID values agree with the key positions? 
    • Yes  : GO to B3.
    • No  : GO to  B4.
  3. B3 CHECK THE DRIVER DOOR AJAR PID 
    • Key in ON position.
    • Monitor the instrument cluster driver door switch PID while opening and closing the driver door.
    • Does the PID agree with the door position? 
    • Yes  : GO to  B6.
    • No  : REFER to INTERIOR LIGHTING to continue diagnosis of the door ajar switches.
  4. B4 CHECK FOR A FAULTY KEY-IN-IGNITION SWITCH 
    • Disconnect: Clockspring C218a.
    • While monitoring the instrument cluster key-in-ignition PID, connect a fused (10A) jumper between the clockspring C218a-1, circuit 158 (BK/PK), harness side and ground.

    • Does the PID read OUT without the jumper wire, and IN when the jumper wire is connected? 
  5. B5 CHECK CIRCUIT 158 (BK/PK) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: Instrument Cluster C220a.
    • Measure the resistance between the clockspring C218a-1, circuit 158 (BK/PK), harness side and the instrument cluster C220a-24, circuit 158 (BK/PK), harness side.

    • Is the resistance less than 5 ohms? 
    • Yes  : GO to B6.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  6. B6 VERIFY THE SYMPTOM 
    • Key in OFF position.
    • Connect: Instrument Cluster C220a.
    • Connect: Clockspring C218a.
    • Key in ON position.
    • Is the symptom still present? 
    • Yes  : GO to B7.
    • No  : The system is working correctly.
  7. B7 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION 
    • Disconnect all the instrument cluster connectors.
    • Check for:
    • corrosion
    • pushed-out pins
    • Connect all the instrument cluster connectors and make sure they seat correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    • Yes  : INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER . TEST the system for normal operation.
    • No  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
