校正代码 17010008 FRT 0.12 注意：除非本程序中另有明确规定，否则上述校正代码和 FRT 反映的是执行本程序（包括关联程序）所需的所有工作。除非明确要求，否则请勿堆叠校正代码。 注意：请参阅平均维修工时，深入了解 FRT 及其创建方式。要提供有关 FRT 值的反馈，请发送电子邮件至LaborTimeFeedback@tesla.com。 注意：请参阅人员保护，确保在执行以下程序时穿戴适当的个人防护装备 (PPE)。

1. Remove the rear underhood apron. See 后裙板总成 ((拆卸和更换)).
2. Disconnect LV battery connector and keep FRL connected
   注

   1x connector, Release LV battery but keep FRL connected, Lift up and release green locking tab, Pull black connector lock outwards to release connection

   

   

   

3. Connecting low-voltage battery maintainer-charger
   注

   Release positive terminal cover, Secure positive terminal to jump post, Secure negative terminal to bolt located between brake fluid reservoir and front trunk, Connect maintainer to power supply, To avoid damaging the vehicle DO NOT allow positive cable to make contact with other metal components, Never have a float charger and the LV battery simultaneously connected for any extended period of time

   

   

   

4. Connect LV battery
   注

   1x connectors, push black connector lock inwards to secure, Engage green locking tab when fully seated

   

   

5. Open LH front door

   

6. Lower LH front window

   

7. Place vehicle in service mode
   注

   Via UI > Controls > Software, Touch and hold "Model 3" for 4 seconds then release, Use screen keyboard to type "service" into dialog box then select OK

   

   

   

8. Disconnect 12v maintainer

   

9. 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-BATTERYSearch for routine in ToolboxLVBMS Reconnect LV BatteryLow 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。
10. Exit Service Mode
    注

    Via UI > Service > Exit, Press and hold "Exit Service Mode" button

    

11. Install the rear underhood apron. See 后裙板总成 ((拆卸和更换)).
