Pinpoint Test H: The Individual Component Illumination Is Inoperative

WARNING: This page is about a different car, the 2009 Ford Pickup, 2009 Ford F550 Super Duty, 2009 Ford F450 Super Duty, and 2009 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. H1 CHECK THE VOLTAGE TO THE SINGLE ILLUMINATION SOURCE 
    • Key in OFF position.
    • Disconnect: Inoperative Illumination Source
    • Place the headlamp switch to the PARKING LAMPS ON position.
    • Rotate the instrument panel dimmer switch to the full illumination position.
    • Measure the voltage between the inoperative illumination source, harness side and ground as follows:
      Component Connector-Pin Circuit
      Four wheel drive switch C284-4 VLN04 (VT/GY)
      Adjustable pedals switch C2089-3 VLN04 (VT/GY)
      Message center switch C265-1 VLN04 (VT/GY)
      Headlamp switch C205-5 VLN04 (VT/GY)
      Power sliding rear window switch C2060-4 VLN04 (VT/GY)
      Parking aid disable switch C2085-3 VLN04 (VT/GY)
      Traction control C280-3 VLN04 (VT/GY)
      Roof opening panel switch C912-5 VLN04 (VT/GY)
      Upfitter switches C2300-2 VLN04 (VT/GY)
    • Is the voltage greater than 10 volts? 
    1. YES  : TURN headlamps off. Go to  H2 .
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  2. H2 CHECK GROUND CIRCUIT TO THE SINGLE ILLUMINATION SOURCE FOR AN OPEN 
    • Key in OFF position.
    • Measure the resistance between the inoperative illumination source, harness side and ground as follows:
      Component Connector-Pin Circuit
      Four wheel drive switch C284-1 GD115 (BK/GY)
      Adjustable pedals switch C2089-4 GD115 (BK/GY)
      Message center switch C265-4 GD115 (BK/GY)
      Headlamp switch C205-10 GD115 (BK/GY)
      Power sliding rear window switch C2060-1 GD115 (BK/GY)
      Parking aid disable switch C2085-2 GD115 (BK/GY)
      Traction control C280-2 GD115 (BK/GY)
      Roof opening panel switch C912-3 GD115 (BK/GY)
      Upfitter switches C2300-3 GD116 (BK/VT)
    • Is the resistance less than 5 ohms? 
    1. YES  : INSTALL a new component in question. TEST the system for normal operation.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
