HVBATT_a018 — Hs Shunt Bar Cal Not Used
Full alert identifier: HVBATT_a018_HsShuntBarCalNotUsed
Alert description
The programmed high side shunt bar resistance calibration is not being used for high voltage (HV) current sensing. The default high side shunt bar resistance will be used and current measurement accuracy may be reduced.
Potential impact
The default high side shunt bar resistance will be used for high voltage (HV) current sensing. High side shunt current measurement accuracy may be reduced.
Set condition
The stored high side shunt bar resistance is invalid or the written gain is outside the allowed tolerance.
Clear condition
The stored high side shunt bar resistance is valid and the written gain is within the allowed tolerance.
