Normal Operation - High Intensity Discharge (HID) Headlamps

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 LH HID relay coil receives power through circuit 29S-LE16 (OG/GN). Ground for the LH HID relay coil is provided through circuit 91S-LE16 (BN/YE) and is controlled by the FEM. Battery voltage is supplied to the LH HID relay through circuit 30-LE31 (RD/YE). When the relay is energized, voltage is switched to the LH ballast through circuit 30S-LE16 (OG/GN). Circuit 31-LEI6 (BK/RD) supplies ground to the LH ballast. The RH HID relay coil receives power through circuit 29S-LE23 (OG/WH). Ground for the RH HID relay coil is provided through circuit 91S-LE23 (BN/WH) and is controlled by the FEM. Battery voltage is supplied to the RH HID relay through circuit 30-LE30 (RD/BU). When the relay is energized, voltage is switched to the RH ballast through circuit 30S-LE23 (OG/WH). Circuit 31-LE23 (BK/WH) supplies ground to the RH ballast. The FEM controls the ground for both HID relay coils. The ballasts provide the necessary voltage to power the HID bulbs. The ballast and HID bulb are replaced as an assembly.
