DRL System
- The DRL system consists of the DRL control module, BCM, lighting switch, tail lights, clearance light, license plate light and headlights.
- When the keyless push start system ignition mode is changed to "ON" with the engine running and the lighting switch is set to "OFF", the DRL control module causes the headlight high beams to light at dimmed brightness.
- The DRL control module uses a reduced duty cycle to dim the headlight high beams.
