Low Beam Headlight Circuit: Description

The headlight relay is turned on by operating the headlight switch.

When the theft deterrent system is activated, it causes the ECU to turn the headlight relay on and off repeatedly at approximately 0.25 second intervals to flash the headlights.

In this condition, if any of the following operations is performed, the ECU turns the headlight relay off to stop the headlight from flashing:

• Unlock the driver door with a key.
• Turn the engine switch on (ACC or IG).
• Unlock the doors with the wireless door lock control system.
