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 approximately 0.2 sec. 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) The front LH or RH door is unlocked with a key.
(2) The ignition switch is turned to the ACC or ON position.
(3) Approximately 1 minute elapses.
