POWER DOOR LOCK CONTROL SYSTEM


  1. CONSTRUCTION


    1. A door control battery is provided, which supplies power to the door lock control system when the battery is damaged due to a collision.

  2. OPERATION


    1. The door control battery charges completely within approximately 90 seconds after the ignition switch is turned ON. Also, the battery finishes discharging through self-discharge approximately 30 minutes after the ignition switch is turned off.

    2. The charged door control battery is used as a redundant power supply to supply power to the main body ECU (multiplex network body ECU) and door lock/unlock relay in order to enable the impact detection door lock release even when the battery becomes disconnected due to a collision.

    3. Even when the door control battery is not charged (the ignition switch is off), the door control battery always supplies power to the main body ECU (multiplex network body ECU) and door lock/unlock relay.
