MV Battery - Recover (Restore)
Correction code
17010008
FRT
0.06
NOTE: Unless
otherwise explicitly stated in the procedure, the above correction code and
FRT reflect all of the work required to perform this procedure, including
the linked procedures. Do
not stack correction codes unless explicitly told to do so.
NOTE: See Flat Rate Times to learn more about FRTs and how they are
created. To provide feedback on FRT values, email ServiceManualFeedback@tesla.com.
NOTE: See Personal Protection to make
sure wearing proper PPE when performing the below procedure. See Ergonomic Precautions for safe and healthy
working practices.

Recover
- Enable Service Mode. See Service Mode.
-
Make sure that no external power
source is connected to the jump post.
-
Make
sure that the high voltage system is supporting the mid voltage system. On the
touchscreen, touch and make sure that the PCS Packside DCDC Support Status indicates Active.
-
Make sure that the MV battery is properly connected. On the touchscreen, touch
and make sure that the Li-ion MV 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 MV Battery MOSFET status indicates Closed (Green).
Figure 1. Li-ion MV Battery MOSFET status Closed -
If the MOSFET status is Open (Orange), the MV battery has not auto-recovered and alert VCLEFT_a478_LVBMS_MOSFET will be present. To attempt the MOSFET to close, Perform the following
routine using Service Mode or Toolbox (see 0005 - Service Modes):PROC_VCLEFT_X_RECONNECT-MV-BATTERYvia Toolbox: (link)via Service Mode: Mid Voltage ➜ Power Distribution ➜ Close MOSFET
Figure 2. Li-ion MV Battery MOSFET status Open - If the previous step does not successfully recover the battery, proceed with using a compatible Tesla Li-ion battery charger to recover the LV battery, and then repeat this procedure.
- Exit Service Mode. See Service Mode.
