Alerts

Signal Name Description Condition Impact Important
This alert is reported by the ActuatorManager_R12 (AM) component when the start up tests in ActuatorTest fails
EPAS ECU actuator management tests failure at startup.
EPAS full loss of assist.
No
This alert is reported by the ActuatorManager_R12 (AM) component when if voltage measurement comparison failed, HW failure.
EPAS ECU actuator monitor detected failure (voltage measurement comparison).
EPAS full loss of assist.
No
This alert is reported by the ActuatorManager_R12 (AM) component when there is a GDU overtemperature.
EPAS ECU GDU device monitor detected failure (overtemperature).
EPAS full loss of assist.
No
This alert is reported by the ActuatorManager_R12 (AM) component when the bridge FET test failed.
EPAS ECU actuator monitor detected failure (bridge-FETs).
EPAS full loss of assist.
No
This alert is reported by the ActuatorManager_R12 (AM) component when there is a GDU failure. GDU internal rail overvoltage check. The GDU contains a set of internal voltage rails and their voltage monitors. The GDU reacts, software just logs it.
EPAS ECU GDU device monitor detected failure (internal voltage voltages).
EPAS full loss of assist.
No
This alert is reported by the ActuatorManager_R12 (AM) component when PWM pattern check failed, probably bridge FET or GDU failure.
EPAS ECU actuator monitor detected failure (PWM phases).
EPAS full loss of assist.
No
This alert is reported by the PowerSupplyManager_R12 (PSUM) when there is a SBC internal failure.
EPAS ECU SBC device internal voltage monitoring failure (VMON_bandgap out of tolerated limit) at startup.
EPAS full loss of assist.
No
This alert is reported by the ActuatorManager_R12 (AM) component when there is a GDU failure. This diagnostic checks the parity of the messages sent by the GDU.
EPAS ECU GDU device monitor detected failure (wrong parity bit on serial communication).
EPAS full loss of assist.
No
This alert is reported by the ActuatorManager_R12 (AM) component when there is a GDU failure. GDU monitors gate-to-source voltage, sets a flag and the software checks it.
EPAS ECU GDU device monitor detected failure (gate-to-source voltage).
EPAS full loss of assist.
No
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 full loss of assist.
No
This alert is reported by the ActuatorManager_R12 (AM) component when there is a GDU failure. This diagnostic reads the critical GDU registers and compares them to their expected values.
EPAS ECU GDU device (management storage) plausilty check (value in GDU differs to the value in MCU) failed.
EPAS reset requested will be performed at the moment when it doesn't providing assist.
No
This alert is reported by the ActuatorManager_R12 (AM) component when there is a GDU failure. This diagnostic tests the primary GDU safety monitors to avoid the existence of latent failures.
EPAS uC memory read access failed (FLASH).
EPAS full loss of assist.
No

EPAS uC ADC peripheral detected hardware channel failure.
EPAS reset
No
This alert is reported by the ADCDriverCD_TC3x component when there is an ADC (analog-digital converter) failure, MCU failure.
EPAS uC peripheral ADC trigger failure and wrong analog aquisition at runtime.
EPAS full loss of assist.
No
This alert is reported when the error reaction manager (ERM) buffer is overflown probably due to SW systematic failure.
EPAS application component ErrorReactionManager detected input queue overflow.
