PRINCIPLES OF OPERATION

The daytime running lamps (DRL) system operates the low beam headlamps at a reduced intensity. The DRL module 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 DRL module remains enabled when the low beam headlamps are turned on.
