EPASTP_a057 — Am Gdu Vds

Full alert identifier: EPASTP_a057_amGduVds

Alert description

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.

Potential impact

EPAS full loss of assist.

Set condition

EPAS ECU actuator driver hardware (MOSFETs) voltages exceed tolerated difference.

Clear condition

EPAS HW failure. EPAS power cycle N times and if persists, the gear needs to be changed.
