System Outline

Key Reminder System 

If the ignition key is in the key cylinder (Unlock warning SW on), the ignition SW is off and the driver door is opened (Door courtesy SW on), then a signal will be input to TERMINAL 12 of the combination meter. This signal activates the combination meter and current flows from TERMINAL 1 of the combination meter to TERMINAL 2 GROUND and the key reminder buzzer will sound.
