  9. 通过“维护模式”或 Toolbox 执行以下例行程序（请参阅0005 - 维护模式）： PROC_VCFRONT_X_RECONNECT-LV-BATTERYvia Toolbox: (link)via Service Mode: Low Voltage ➜ Power Distribution ➜ Close MOSFET
  10. 如果未通过上述步骤成功完成低压电池自动恢复，请使用 Tesla 锂离子电池充电器。
    • 确认电池并未处于高电流放电或自保护状态。
    • 转至Service Mode > Low Voltage > Power Distribution > LV Battery，确认低压电池充电状态在上升。
    • 确认低压电池 MOSFET 状态为Closed。
