Gen3/tasks/PROC_HVBMS_X_CLEAR-BLOCKED-CONTACTORS
Clears open Voltage Sensing Harness (VSH) latch alerts and isolation counters. Resets the High Voltage Processor (HVP) and High Voltage Battery Management System (HVBMS) Electronic Control Units (ECU) in an attempt to clear blocked contactors. Even in the case all internal routines PASS, contactors may still be blocked from closing due to other external conditions.

Clears the Voltage Sense harness (VSH) alert BMS_a119_Fast_Open_Vsh_Detected latch within the HVBMS NVRAM. This routine shall only be executed after installing a new/remanufactured HV battery.
PROC_HVBMS_X_RESET-VSH-FAULT
This routine clears the High Voltage Battery Management System (HVBMS) isolation counters, which clears BMS_a027_SW_Repeated_Isolation_Failure_In_Drive and BMS_a172_SW_Isolation_Failure_In_Drive_Warning alerts. Execute this routine after repairing any isolation issue on the vehicle's High Voltage (HV) system. The HVBMS isolation counters latch the alerts BMS_a027 and BMS_a172 when reaching a certain count threshold.
PROC_HVBMS_X_RESET-ISOLATION-COUNTERS
This routine checks the HVBMS connections to the Battery Monitoring Board (BMB) and the Voltage Sense Harness (VSH).
TEST-SELF_HVBMS_X_BMB-COMMS-VSH
This routine will test if the High Voltage Battery Management System (HVBMS) is communicating over CAN to the Gateway.
