Circuit Description
WARNING: This page is about a different car, the 2002 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
When the engine immobilizer system is preparing to set, this circuit turns the security indicator light ON. When the system has been set, it continually keeps the security indicator light ON for 0.8 seconds and turns it OFF for 1.2 seconds, thus the security indicator light blinks.
