Circuit Description
When the anti-theft system is activated, it causes the relay in the ECU to switch ON and OFF at approximately 0.4 second intervals. This switches the headlight control relay ON and OFF, thus flashing the headlights. See Fig 1. In this condition, if any of the following operations is done, the relay in the ECU goes OFF and the headlight control relay switches OFF, thus stopping the headlights flashing:
- Unlock the front left hand or right hand door with a key.
- Turn the ignition switch to ACC or ON position.
- Unlock the doors with the wireless door lock control system.
- Wait for approximately 60 seconds.
