Pinpoint Test K : All High Beams Are On Continuously - Vehicles With Halogen Headlamps
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.
- K1 CHECK THE LH (LEFT-HAND) MULTIFUNCTION SWITCH INPUT
- Using a diagnostic scan tool, view SCCM Parameter Identifications (PIDs).
- Monitor the SCCM High Beam Switch (HIGH_BEAM_SW) PID while placing the LH steering column multifunction switch in the HIGH BEAM and LOW BEAM positions.
Do the PID values agree with the LH steering column multifunction switch position?
Yes GO to K3 No INSTALL a new LH steering column multifunction switch. REFER to: Steering Column Multifunction Switch LH . TEST the system for normal operation. If the concern still exists, GO to K2 - K2 CHECK FOR CORRECT SCCM (STEERING COLUMN CONTROL MODULE) 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 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, INSTALL a new SCCM. For vehicles without adaptive steering, REFER to: Steering Column Control Module (SCCM) . For vehicles with adaptive steering, REFER to: Steering Column Control Module (SCCM) - Vehicles With: Adaptive Steering . 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. - K3 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.
