  2. OPERATION


    1. The door control battery charges completely within approximately 90 seconds after the engine switch is turned on (IG). Also, the battery finishes discharging through self-discharge approximately 40 minutes after the engine 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 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 engine switch is off), the door control battery always supplies power to the main body ECU and door lock/unlock relay.
