Circuit Description
WARNING: This page is about a different car, the 2003 Lexus IS 300 and 2002 Lexus IS 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, this circuit lights up the indicator light. When the system has been set, it continually turns the indicator light ON for 0.2 second and turns it off for 1.8 seconds, thus blinking the indicator light. See Fig 1.
