Pinpoint Test A : Both Spot Lamps Are Inoperative

WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

  1. A1 CHECK THE LOW BEAM OPERATION

    • Ignition ON.

    • Place the headlamp switch in the PARKLAMPS position.

    • Using the spot lamp switch, enable the LH and RH spot lamp.

    Do the spot lamps illuminate? 

    Yes  The system is operating correctly at this time. INFORM the customer of the conditions under which the spot lamps operate. REFER to: Exterior Lighting - System Operation and Component Description .
    No  GO to  A2

  2. A2 CHECK FOR VOLTAGE TO THE SPOT LAMP MODULE

    • Place the headlamp switch in the OFF position.

    • Ignition OFF.

    • Disconnect: Spot Lamp Module C2506B.

    • Ignition ON.

    • Measure:

      		 Ground

    Is the voltage greater than 11 volts? 

    Yes  GO to  A3
    No  VERIFY the BJB fuse 90 (10A) is OK. If OK, REPAIR the circuit. If not OK, REFER to OEM Wiring Diagrams to identify the possible causes of the circuit short.

  3. A3 CHECK FOR ENABLE VOLTAGE TO THE SPOT LAMP MODULE

    • Place the headlamp switch in the PARKLAMPS position.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2506B-2

      		 Ground

    Is the voltage greater than 11 volts? 

    Yes  GO to  A7
    No  GO to  A4

  4. A4 REPEAT THE ON-DEMAND SELF-TEST AND CHECK FOR ENABLE VOLTAGE TO THE SPOT LAMP MODULE

    • Using a diagnostic scan tool, perform the BCM self-test.

    • Clear the Diagnostic Trouble Codes (DTCs) and repeat the self-test (required to enable the lamp output driver if DTC U1000:00 is present).

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2506B-2
      GFD410225Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the voltage greater than 11 volts? 

    Yes  INSTALL a new spot lamp module. REFER to: Spot Lamp Control Module .
    No  GO to  A5

  5. A5 CHECK THE SPOT LAMP MODULE ENABLE VOLTAGE CIRCUIT FOR A SHORT TO GROUND

    • Place the headlamp switch in the OFF position.

    • Ignition OFF.

    • Disconnect: BCM C2280E.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2506B-2
      GFD410226Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the resistance greater than 10, 000 ohms? 

    Yes  GO to  A6
    No  REPAIR the circuit. After the repair: If no Diagnostic Trouble Codes (DTCs) are present, TEST the system for normal operation. If DTC U1000:00 is present, CLEAR the Diagnostic Trouble Codes (DTCs) and REPEAT the self-test (required to enable the lamp output driver if DTC U1000:00 is present). If DTC U3000:49 is present, Refer to BCM Guided Routine .

  6. A6 CHECK THE SPOT LAMP MODULE ENABLE VOLTAGE CIRCUIT FOR AN OPEN

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2506B-2
      GFD410226Courtesy of FORD MOTOR COMPANY
      		 C2280E-11

    Is the resistance less than 3 ohms? 

    Yes  GO to  A10
    No  REPAIR the circuit.

  7. A7 CHECK THE SPOT LAMP MODULE GROUND CIRCUIT

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2506B-2
      GFD410225Courtesy of FORD MOTOR COMPANY
      		 C2506B-5

    Is the voltage greater than 11 volts? 

    Yes  GO to  A8
    No  REPAIR the circuit.

  8. A8 CHECK THE SPOT LAMP SWITCH INPUT

    • Place the headlamp switch in the OFF position.

    • Ignition OFF.

    • Disconnect: Spot Lamp Module C2506A.

    • While pressing the LH spot lamp switch, measure:
      Positive Lead Measurement / Action Negative Lead
      C2506A-1
      GFD410226Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the resistance less than 3 ohms while pressing the LH spot lamp switch? 

    Yes  INSTALL a new spot lamp module. REFER to: Spot Lamp Control Module .
    No  GO to  A9

  9. A9 CHECK THE SPOT LAMP SWITCH GROUND CIRCUIT FOR AN OPEN

    • Disconnect: Spot Lamp Switch C2507.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2507-3
      GFD410226Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the resistance less than 3 ohms? 

    Yes  INSTALL a new spot lamp switch. REFER to: Spot Lamp Switch .
    No  REPAIR the circuit.

  10. A10 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

    • Disconnect and inspect all BCM connectors.

    • Repair:

      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary

    • Reconnect the BCM connectors. Make sure they seat and latch correctly.

    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, Refer to BCM Guided Routine .
    No  The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
