1. Remove the rear underhood apron. See 前备箱挡板 - 后部（拆卸和更换）.
2. Disconnect LV battery connector and keep FRL connected
   注

   2x connectors, Lift up and release green locking tab, Pull black connector lock outwards to release connection, Keep FRL connected

   

   

3. Connect 12V maintainer while LV battery is connected and cycle contactors on
   注

   1x tab, Connect 12V support while LV battery is connected, Release jump post cover behind wiper module, Place rag between multisystem beam and jump post, Prevent shorting positive cable to ground, Route positive clamp between brake fluid reservoir and wiper module, Secure positive terminal to jump post, Secure negative terminal to multisystem beam, Connect maintainer to power supply, Contactors will turn on and there will be an audible click

   

   

   

   

   

4. Secure LV battery connector
   注

   1x connector, Seat LV battery connection and push black connector lock inwards to secure, Engage upper locking tab when fully seated

   

5. Open the LH front door.
6. Lower both front windows.
7. Activate Service Mode using the touchscreen.

   

   

8. Remove 12V maintainer
   注

   Remove 12V support after firmware is completed, Unplug maintainer first and then remove from posts, Return cap to positive post

   

   

9. Navigate to Power Distribution
   注

   Via Service UI select Low Voltage > Power Distribution

   

   

10. 确认低压电池的状态。
    注

    如果功率转换系统 (PCS) 支持启用 2 分钟后，出现VCLEFT_a478_LVBMS_MOSFET_Open或VCBATT_a478_LVBMS_MOSFET_Open警告，说明低压电池尚未自动恢复。可以通过触摸屏或 Toolbox 尝试手动进行自动恢复：

    • 触摸屏：Service Mode > Low Voltage > Power Distribution > Close MOSFET
    • Toolbox：运行ActionPROC_VCFRONT_X_RECONNECT-LV-BATTERYvia Toolbox: (link)via Service Mode: Low Voltage ➜ Power Distribution ➜ Close MOSFET

    注

    如果通过上述步骤并未成功完成低压电池自动恢复，请使用 Tesla 锂离子电池充电器（仍在开发中）进行电池恢复。

    • 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。
11. Exit Service mode
    注

    Press and hold the Exit Service Mode button for 3 seconds

    

12. Install the rear underhood apron. See 前备箱挡板 - 后部（拆卸和更换）.
