EPASTS_a095 — Md Model Based Motor Integrity Check
Full alert identifier: EPASTS_a095_mdModelBasedMotorIntegrityCheck
Alert description
This alert is reported by the MotorDiagnostics_R12 (MD) component if the difference between estimated and measured phase currents is greater than the limit or the QoS of the phase currents is QOS_CS_ERROR or the qualifier of the estimated phase currents is SEN_NOT_AVAILABLE for longer than the given debounce time.
Potential impact
EPAS full loss of assist.
Set condition
EPAS model diagnostics detects integrity failure on the observed motor behavior to a theoretical motor model (phase cuts or short circuit of the phase relays failures).
Clear condition
EPAS power cycle.
