Panic Mode Function
WARNING: This page is about a different car, the 2002 Lexus GS 430 and 2002 Lexus GS 300. However, it is still accessible from the selected car via links, so may be relevant.
When the lock switch on the transmitter is kept pressed for approximately 2.5 seconds, the body ECU No. 1 receives the signal and enters the panic mode. The anti-theft alarm goes on upon receiving the signal, the body ECU No. 1, and the headlights and taillights flash through the communication of the body ECU and door ECU etc. At this time, when any switch on the transmitter is pressed, the panic mode is cancelled, the anti-theft alarm is stopped, and the headlights and taillights go off.
