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.
