Lighting and Horns: Description and Operation

Exterior Lights System Description

Daytime Running Lights

The daytime running lights system includes the MICU, the left and right high beam headlights, the parking brake switch, and the DRL indication on the multi-information display (With multi-information display) or the DRL indicator (Without multi-information display). The daytime running lights operate with the ignition switch turned to ON (II), the headlights off (headlight switch OFF or in the parking position), and the parking brake released. When the daytime running lights are on, the MICU turns each relative daytime running lights control circuit on and off (duty cycle), which provides a reduced voltage (approximately 6-8 volts) to the high beam headlights (via the 12 and No. 13 fuses in the under-dash fuse/relay box); the high beam headlights come on with reduced brightness. The MICU also sends signals to the gauge control module, and the DRL indication is indicated by the lights-on indicator.

NOTE:

- The daytime running lights are disabled when the ignition switch is turned to LOCK (0). To keep the daytime running lights from coming on, apply the parking brake switch while the ignition switch is in LOCK (0) position. When you then turn the ignition switch back to ON (II) the daytime running lights will not come on until the parking brake is released.
- The headlights revert to normal operation when you turn them on with the headlight switch.
