Daytime Running Light Relay Circuit: Description

This function is designed to automatically illuminate the headlights (dimmed high beams), during the daytime to make the car more visible to other vehicles.

The main body ECU and power distributor control this function. The main body ECU transmits a turn ON signal to the power distributor and the power distributor illuminates the high beams using a duty control.

The daytime running lights come on when the conditions given below are met:

• Ignition switch on (IG).
• Engine speed signal input (engine running condition).
• Parking brake switch is OFF.
• Light control switch is not in DRL OFF.
• Light control switch is in OFF, TAIL or AUTO position (and the headlights are not turned on via the automatic light control).
