Pinpoint Test D: The Steering Wheel Control Illumination Is Inoperative

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. D1 CHECK THE OTHER DIMMABLE LIGHTING SWITCHES 
    • Ignition OFF.
    • Place the headlamp switch in the PARKING LAMPS ON position.
    • Increase the backlighting brightness to the highest setting.
    • Are all the dimmable switches inoperative? 
  2. D2 CHECK FOR VOLTAGE TO THE CLOCKSPRING 
    • Place the headlamp switch in the OFF position.
    • Depower the Supplemental Restraint System (SRS). Refer to SUPPLEMENTAL RESTRAINT SYSTEM -- FUSION, MILAN & MKZ article.
    • Disconnect: Clockspring C218a.
    • Connect: Negative Battery Cable.
    • Place the headlamp switch in the PARKING LAMPS ON position.
    • Rotate the instrument panel dimmer switch to the full illumination position.
    • Measure the voltage between the clockspring C218a-16, circuit VLN04 (VT/GY) (Fusion/Milan) or circuit VLN37 (BU/WH) (MKZ), harness side and ground.

    • Is the voltage greater than 10 volts? 
  3. D3 CHECK FOR VOLTAGE TO THE CLOCKSPRING USING THE CONNECTOR GROUND 
    • Measure the voltage between the clockspring C218a-16, circuit VLN04 (VT/GY) (Fusion/Milan) or circuit VLN37 (BU/WH) (MKZ), harness side and the clockspring C218a-7, circuit GD116 (BK/VT), harness side.

    • Is the voltage greater than 10 volts? 
  4. D4 CHECK THE CLOCKSPRING FOR AN OPEN 
    • Remove the driver air bag module. Refer to SUPPLEMENTAL RESTRAINT SYSTEM -- FUSION, MILAN & MKZ article.
    • Disconnect: Upper Clockspring C218b.
    • Measure the resistance between the clockspring C218a pin 16, component side and the upper clockspring C218b pin 7, component side.

    • Are the resistances less than 5 ohms? 
  5. D5 CHECK THE STEERING WHEEL HARNESS CIRCUIT FOR AN OPEN 
    • Disconnect: Steering Wheel Switches C2997 and C2998.
    • Measure the resistance between the upper clockspring C218b-7, circuit VLN04 (VT/GY), harness side and the LH steering wheel switch C2998-2, circuit VLN04 (VT/GY), harness side; and between the upper clockspring C218b-7, circuit VLN04 (VT/GY), harness side and the RH steering wheel switch C2997-1, circuit VLN04 (VT/GY), harness side.

    • Are the resistances less than 5 ohms? 
  6. D6 CHECK THE STEERING WHEEL HARNESS GROUND CIRCUIT FOR AN OPEN 
    • Measure the resistance between the LH steering wheel switch C2998-4, circuit GD165 (BK), harness side and the clockspring C218b-2, circuit GD165 (BK), harness side; and between the RH steering wheel switch C2997-3, circuit GD165 (BK), harness side and the clockspring C218b-2, circuit GD165 (BK), harness side.
