5. DOOR LOCK ACTUATOR SWITCH INPUT CIRCUIT

Description of Operation
When a door is locked by the lock knob or the key, the door lock actuator switch is switched OFF, and HIGH-level signals are sent to the ECU. These signals activate the timer circuit of the ECU, thereby causing the activation circuit to function, thus activating the door lock actuator of all doors.
