General Information

Depending on the outside light conditions, the Daytime Running Lights (DRL) Module automatically operates either the Headlights or the Headlights and Front/Tail Lights. The gear selector must be out of "PARK/NEUTRAL" (Automatic Transaxle) or the Park Brake must be released (Manual Transaxle). The DRL Module operates in two modes:
^ In the Day Mode, the LO Beam and HI Beam Headlights are lit at a reduced brilliance.
^ In the Night Mode, the LO or HI Beam Headlights are lit at full brilliance and the Front Marker, Park and Tail Lights are lit.

When the Photoresistor senses low ambient light, the DRL Module operates in Day Mode. The Day Mode contacts close, applying voltage to LO Beam and HI Beam Headlights through CKT 593. The LO Beam and HI Beam Headlights are lit at a reduced brilliance.

When the Photoresistor senses darkness, the DRL Module operates in Night Mode. The Night Mode contacts close, applying voltage to the LO or HI Beam Headlights and other Exterior Lights through the same circuit path as when the Headlight Switch is in "HEAD."

The Fog Light Switch receives battery voltage from the TAIL LPS Fuse. With the Headlight Switch in "PARK" or "HEAD," battery voltage is applied to the Fog Light Switch through the INST LPS Fuse. With the LO Beam Headlights ON and the Fog Light Switch "ON," battery voltage is applied to the coil of the Fog Light Relay. The Fog Light Relay coil receives its ground signal through the DRL Module. The relay is energized, and voltage from Horn Fuse is applied to the Fog Lights through the Fog Light Relay contacts. If the HI Beam Headlights are turned ON, battery voltage is applied to the HI Beam Input of the DRL Module. The DRL Module removes ground from the Fog Light Relay, and the relay is de-energized, removing battery voltage from the Fog Lights.
