Daytime Running Light Operation
When the engine is started, a signal from the generator is input into TERMINAL (A) 14 of the body ECU. At this time, if the
parking brake lever is pulled up (Parking brake SW ON), the body ECU is not activated, and the daytime running light
system does not operate.
When the parking brake lever is released (Parking brake SW OFF), a signal is input into TERMINAL (B) 2 of the body ECU.
This activates the body ECU and the headlight turns on.
