System Outline

Current is always applied from the ECU-B fuse to TERMINAL 3 of the combination meter. When the ignition SW is turned to ON position, the current from the MET IG2 fuse flows to TERMINAL 4 of the combination meter.

Key Reminder System 

When the driver door is opened when the ignition SW off but the ignition key is still in the key cylinder (Unlock warning SW on), a signal is input from the unlock warning SW to TERMINAL 7 of the combination meter, and from the door courtesy SW (Driver's side) to TERMINAL 8 of the combination meter. As a result, the buzzer in the combination meter sounds, warning the driver that the key is still in the key cylinder.
