Daytime Running Lamps (DRL)

Principles of Operation

The LCM controls the Daytime Running Lamps (DRL) by using various inputs to determine whether or not the DRL should be illuminated. These inputs include:

- Ignition switch position
- Headlamp switch position
- Headlamps on or off
- Transmission gear selection

The LCM can be configured to turn the DRL on for this vehicle. Refer to Information Bus for information on this programmable parameter.
