Key Reminder System

If the driver's side door is opened with the power supply set at ACC or OFF position and with the electrical key remained in the key slot, signal from key slot is input to TERMINAL KSW of body ECU and that from courtesy SW at driver's side is input to TERMINAL DCTY of body ECU. The signal from body ECU to combination meter activates warning buzzer to send a message to the driver that electrical key remains in the key slot.
