Normal Operation

WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

The instrument cluster monitors the headlamp switch position by sending out voltage reference signals to the headlamp switch. If a problem is detected with the low beam signal circuit (8-LE21 [GY/OG]), the headlamps off signal circuit (10-LE21 [GY/OG]) or the signal return circuit (9-LE29 [BN/GN]) from the headlamp switch, the instrument cluster will default the headlamps and parking lamps ON. When the headlamp switch is in the headlamps ON position, the instrument cluster sends a signal to the front electronic module (FEM) to illuminate the headlamps.
