Circuit Description
WARNING: This page is about a different car, the 2002 Toyota Sequoia. However, it is still accessible from the selected car via links, so may be relevant.
Taillight relay will be "ON" by operating the taillight switch. The transistor which activates the tail light relay has two sorts: one activates by the tail light switch for fail safe and the other activates 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, thus flashing the taillights (See the wiring diagram below).
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, thus stopping the taillights flashing:
- Unlock the front LH or RH 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.
