Taillight Control Relay Circuit
CIRCUIT DESCRIPTIONWhen the theft deterrent system is activated, it causes the Tr in the ECU to switch ON and OFF at approximately 0.4 sec. intervals. This switches the taillight control relay ON and OFF, thus flashing the taillights.
In this condition, if any of the following operations is done, the Tr in the ECU goes OFF and the taillight control relay switches OFF, thus stopping the taillights flashing:
1. Unlock the front LH or RH door with key.
2. Turn the ignition switch to ACC or ON position.
3. Unlock the doors with the wireless door lock control system.
4. Wait for approximately 60 seconds.
5. Push the panic switch of the wireless door lock control system.
