B1D01 LINCOLN Description
When the Body Control Module (BCM) receives a message that the headlamp switch is in the HEADLAMPS ON position and the multifunction switch is in the LOW BEAM position (or the autolamps feature has requested the headlamps on), the BCM provides voltage through the headlamp output circuits to the Left (LH) and Right (RH) low beam headlamps. The BCM also provides an overload protection of the low beam output circuits. When an excessive current draw is detected, the BCM disables the affected low beam circuit driver. This Diagnostic Trouble Code (DTC) sets when the BCM detects a short to ground from the RH low beam output circuit.
