- 2026-09-22: Updated the "Close MOSFET" touchscreen process and added a closeout routine step.
- 2025-05-15: Updated procedure and added images.
- 2025-04-23: Updated Service Mode instructions.
LV Battery Recover
注
The LV battery won't recover unless the HV system is healthy and supporting the vehicle. Make sure that the HV system is functioning correctly before attempting to recover the LV battery.
- Enable Service Mode. See 维护模式.
-
Make sure that no external power
source is connected to the jump post.
-
Make sure that the high voltage system is supporting the low voltage system. On the touchscreen, touch and make sure that the PCS DCDC Support Status indicates Active.
-
Make sure that the LV battery is properly connected. On the touchscreen, touch and make sure that the Li-ion LV Battery ECPA (Electrical Connector Position Assurance) status indicates Closed.
-
Confirm that the Li-ion LV battery MOSFET status is Closed. On the touchscreen, touch and make sure that the Li-ion LV Battery MOSFET status indicates Closed (Green).
图 1. Li-ion LV Battery MOSFET status Closed -
If the MOSFET status is Open (Orange), the LV battery has not auto-recovered and the following alert(s) will be present:
- VCFRONT_a478_LVBMS_MOSFET_Open
图 2. Li-ion LV Battery MOSFET status Open -
On the touchscreen, touch , and allow the routine to complete.
- If the previous step does not successfully recover the battery, proceed with using the Tesla LV Li-ion battery charger to recover the LV battery, and then repeat this procedure.
- Exit Service Mode. See 维护模式.
