Headlight Control Relay Circuit
CIRCUIT DESCRIPTION
When the theft deterrent system is activated, it causes the Tr in the ECU to switch ON and OFF at intervals.
This switches the headlight control relay ON and OFF, thus flashing the headlights (See the wiring diagram
below).
In this condition, if any of the following operations is done, the Tr in the ECU goes OFF and the headlight
control relay switches OFF, thus stopping the headlights flashing:
(1) Unlock the front LH or RH door with the key.
(2) Turn the ignition switch to ACC or ON position.
(3) Unlock the doors by the wireless door lock control system.
(4) Wait for approximately 60 seconds.
(5) Push the panic switch of the wireless door lock control system.
