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.
