PINPOINT TEST L : The High Beams Are On Continuously

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

  1. L1 CHECK THE HIGH BEAM OPERATION

    • Ignition ON.
    • Place the headlamp switch in the HEADLAMPS position.
    • Place the LH steering column multifunction switch in the LOW BEAMS position and observe the headlamps.

    Are both high beams illuminated? 

    Yes  GO to  L2
    No  GO to  L3

  2. L2 CHECK THE MULTIFUNCTION SWITCH INPUT

    • Using a diagnostic scan tool, view SCCM PIDs.
    • Monitor the SCCM HEADLAMP_SW PID while placing the LH steering column multifunction switch in the FLASH-TO-PASS, LOW BEAM and HIGH BEAM positions.

    Do the PID values agree with the LH steering column multifunction switch positions? 

    Yes  GO to  L4
    No  INSTALL a new LH steering column multifunction switch. REFER to Steering Column Switches .If the concern still exists, GO to  L5

  3. L3 CHECK THE BCM HIGH BEAM OUTPUT CIRCUIT FOR A SHORT TO VOLTAGE

    • Ignition OFF.
    • Place the headlamp switch in the OFF position.
    • Disconnect: Illuminated Headlamp.
    • Ignition ON.
    • Place the headlamp switch in the HEADLAMPS position.
    • Measure:

      Headlamp-Left

    Is any voltage present? 

    Yes  REPAIR the circuit in question.
    No  GO to  L4

  4. L4 CHECK FOR CORRECT BCM 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 TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, BCM Hardware Testing .
    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.

  5. L5 CHECK FOR CORRECT SCCM OPERATION

    • Disconnect and inspect all SCCM 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 SCCM 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 TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new SCCM. REFER to Steering Column Switches .
    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.
