Principles of Operation (How Does It Work?)
The DRL function is integral to the Lighting Control Module (LCM) on Canadian vehicles. The LCM will activate the headlamps at approximately half
illumination when the engine is running. The engine running signal is provided to the LCM from the generator L terminal.
If the parking brake is applied before the engine is started, the DRL will not be activated by the LCM. After the engine is running, the DRL will be
activated when the parking brake is released. Thereafter, when the parking brake is applied, the DRL will continue to operate.
