Circuit Description
WARNING: This page is about a different car, the 2002 Lexus RX 300. However, it is still accessible from the selected car via links, so may be relevant.
When the anti-theft system is preparing to set, the circuit lights up the indicator light. When the system has been set, it continually turns the indicator on for 1 second and turns it off for 1 second, thus blinking the indicator light. This anti-theft indicator is connected to the ECM and outputs the key judgement of the immobilizer. See Fig 1.
