When it clears

Valid DIR_torqueActual and Valid DIR_axleTorqueQF are received for 100 milliseconds.

Potential impact

The Decoupled Power Brake (DPB) may not generate brake torque requested by DI_brakeTorqueCommandFull and instead generate brake torque requested by DI_brakeTorqueCommand. There may be an issue with the transmitting Electronic Control Unit (ECU).
