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 illuminate the low beam headlamps at a reduced intensity when the following conditions are met:
- The headlamp switch is not in the HEADLAMPS ON position.
- The ignition switch is in the RUN position.
- The transmission is not in PARK (P).
