LV Battery Recover

참고
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.
  1. Enable Service Mode. See 정비 모드.
  2. Make sure that no external power source is connected to the jump post.
  3. Make sure that the high voltage system is supporting the low voltage system. On the touchscreen, touch Service Mode > Low Voltage > Power Distribution and make sure that the PCS DCDC Support Status indicates Active.
  4. Make sure that the LV battery is properly connected. On the touchscreen, touch Service Mode > Low Voltage > Power Distribution and make sure that the Li-ion LV Battery ECPA (Electrical Connector Position Assurance) status indicates Closed.
  5. Confirm that the Li-ion LV battery MOSFET status is Closed. On the touchscreen, touch Service Mode > Low Voltage > Power Distribution and make sure that the Li-ion LV Battery MOSFET status indicates Closed (Green).
    그림 1. Li-ion LV Battery MOSFET status Closed
  6. 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
    그림 2. Li-ion LV Battery MOSFET status Open
  7. On the touchscreen, touch Close MOSFET > Run, and allow the routine to complete.
  8. 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.
  9. Exit Service Mode. See 정비 모드.
