DAYTIME RUNNING LIGHT OPERATION
When the engine is started, the generator signal is input of the body ECU. At this time, if the parking brake pedal is depressed (Parking brake SW ON), the body ECU is not activated, and the daytime running light system does not operate.

When the parking brake pedal is released (Parking brake SW OFF), a signal is input into TERMINAL (C) 3 of the body ECU.
This activates the body ECU and the headlight turns on.
