Door Sensor/Switch (For Alarm): Description and Operation

DOOR SWITCH LEFT OR RIGHT
These switches detect the open/close condition of the doors. (This is a condition for arming the system.)

ALL DOORS
One of these switches is located at each door. They detect the open or closed condition of the doors, and when any one of them is opened, a ground signal is sent to the ECU.

When this signal is input while the system is armed, the ECU functions to activate the alarm.
