Circuit Description

WARNING: This page is about a different car, the 2002 Toyota MR2. However, it is still accessible from the selected car via links, so may be relevant.

The door unlock detection switch is built in the door lock motor assembly. This switch is ON when the door lock knob is in the unlock position and OFF when the lock knob is in the lock position. The body ECU detects the door lock knob conditions in this circuit. It is used as one of the operating conditions for the key confinement prevention function.
