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 with the ignition SW off and ignition key remaining 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 goes on and warns the driver that the key is remaining in the key cylinder.
