Taillight Relay Circuit

Taillight Relay Circuit

CIRCUIT DESCRIPTION

Taillight relay will be "ON" by operating the taillight switch. The transistor which activates the tail light relay has two sorts: one is activated by the tail light switch for fail safe and the other is activated by CPU.

When the theft deterrent system is activated, it causes the transistor in the ECU to switch ON and OFF at approximately 0.4 second intervals. This switches the taillight control relay ON and OFF, and thus flashing the taillights (See the wiring diagram ).

In this condition, if any of the following operations is done, the transistor in the ECU goes OFF and the taillight control relay switches OFF, and thus stopping the taillights flashing:
1. Unlock the front LH or RH door with a key.
2. Turn the ignition switch to ON position.
3. Unlock the doors with the wireless door lock control system.
4. Wait for approximately 60 seconds.
