This alert is reported by the PhaseCurrentProvider_R12 (PCP) component if both primary and secondary current measurement channels are in saturation state and the debounce counter reaches its limit. If both current measurement channels are saturated, we assume that there is a shorted FET in the bridge. This diagnostic signals it.
