This alert is reported by the ActuatorManager_R12 (AM) component when there is a GDU failure. This diagnostic checks the voltage level between the drain/source of each MOSFET in the primary actuator path and reacts if the voltage level is higher than specified.

This alert is reported by the ActuatorManager_R12 (AM) component when there is a GDU failure. This diagnostic checks the voltage level between the drain/source of each MOSFET in the primary actuator path and reacts if the voltage level is higher than specified.
EPAS ECU actuator driver hardware (MOSFETs) voltages exceed tolerated difference.
EPAS HW failure. EPAS power cycle N times and if persists, the gear needs to be changed.
