ModelSX/tasks/PROC_BMS_X_CLEAR-SOC1-SNAPSHOT
This routine clears the BMS SOC1 snapshot which in effect clears all HV battery brick weak short metrics/alerts. This routine shall ONLY be executed after installing a new/remanufactured HV battery or on rare occasion when instructed to do so by engineering. The routine will clear BMS_w117_SW_Delta_SOC_Weak_Short and BMS_u029_dSoc_Limiting if actively set on the vehicle.

No user inputs are listed in this firmware.
This routine will execute various Battery Management System (BMS) clear/reset routines in an attempt to clear blocked pack contactors. Keep in mind that even if all internal routines PASS, pack contactors may still be blocked from closing due to other extrinsic conditions.
PROC_BMS_X_CLEAR-BLOCKED-CONTACTORS
Clears the Battery Management System (BMS) isolation counters, which clears BMS_w/f027_SW_Drive_Iso_Repeated and BMS_w/f172_SW_Drive_Iso_Warning alerts. Execute this routine after repairing any isolation issue on the vehicle's High Voltage (HV) system. The BMS isolation counters latch the alerts BMS_w/f027 and BMS_w/f172 when reaching a specific count threshold.
PROC_BMS_X_CLEAR-ISOLATION-ALERT-COUNTERS
This routine will test if the Battery Management System (BMS) is communicating over CAN to the Gateway.
PING-TP_BMS
This routine creates a backup copy of data from the Battery Management System (BMS) ECU and saves it onto the car computer. The backup data is needed when performing a BMS ECU Restore.
