System Outline

Key Reminder System 

If the driver door is opened and the ignition SW is in the ACC or OFF position and the ignition key remains inserted in the key cylinder (The unlock warning SW is on), the signal from the unlock warning SW is input to TERMINAL (D) 21 of the body ECU and the signal from the door courtesy SW LH is input to TERMINAL (B) 14 of body ECU. As a result, the buzzer in the combination meter will sound to warn the driver that the ignition key is still in the key cylinder.
