Daytime Running Lamp: Description and Operation

DAYTIME RUNNING LAMPS (DRL)

NOTE: The smart junction box (SJB) must be configured when installing a new module.

The DRL system operates the low-beam headlamps at a reduced intensity. The SJB supplies pulse width modulated (PWM) voltage to the low-beam headlamps when the following conditions are met:
- The high beam headlamps are not on.
- The ignition switch is in the RUN position.
- The parking brake control is released.

The DRL system utilizes the existing circuitry in the vehicle.
