Key Buzzer Schematic

Work In Progress. More To Come.
Note: This is not a procedure yet to disable the chime with Driver's Door open and the key in the Ignition. It is is a study of the circuits to find a possible solution.


System Outline
The current is applied at all times to TERMINAL 3 of the combination meter through the ECU–B fuse. When the ignition SW is turned to ON position, the current flows to TERMINAL 4 of the combination meter through the MET IG2 fuse. When the light control SW is turned to TAIL or HEAD position, current is applied to TERMINAL 6 of the combination meter through the PANEL fuse.
Light Reminder System
When the light control SW is in TAIL or HEAD position, the ignition SW turned to OFF from ON position, ignition key is not in the key cylinder and the driver’s door opened (Door courtesy SW on), the current flows to TERMINAL 4 of the combination meter stops. As a result, the combination meter is activated and current flows from TERMINAL 3 of the combination meter, the buzzer in the combination meter goes on to remind the light is lighting up.
