Alerts

Signal Name Description Condition Impact
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.
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.
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.
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.
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.
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.
This alert is reported by the ADCDriverCD_TC3x component when there is an ADC (analog-digital converter) failure, MCU failure.
EPAS uC ADC peripheral detected hardware channel failure.
EPAS reset
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.
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.
EPAS full loss of assist.
This alert is reported by the ErrorLogger (ERL) component when the internal general error logging buffer overflowed.
EPAS application component ErrorLogger detected logging buffer overflow.
EPAS might not be able to report some alerts and update alertMartrix.
This alert is reported by the ExternalPowerManager_A8140x (EPM) component in case of under voltage on the first charge pump.
EPAS ECU EPM device voltage monitoring failed (undervoltage detected on first charge pump).
EPAS full loss of assist.
This alert is reported by the ExternalPowerManager_A8140x (EPM) component when it detects VREG over and under voltage.
EPAS ECU EPM device voltage monitoring failed (VREG over/under-voltage).
EPAS full loss of assist.
This alert is reported by the MCUSafetyStartupChecks_TC3x (MCUSSC) component when MCU oscillator was not reliable during startup.
EPAS uC oscillator failure (not reliable) at startup.
EPAS full loss of assist.
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.
This alert is reported by the SystemBasisChipManager_A8140x (SBCM) component in case SBC EEPROM is corrupted.
EPAS ECU SBC EEPROM device memory failure (corrupted) at startup.
EPAS full loss of assist.
This alert is reported by the SystemBasisChipManager_A8140x (SBCM) component in case the watchdog is in DISABLED state which is not allowed at all.
EPAS ECU SBC device watchdog is in disabled state at runtime.
EPAS full loss of assist.
This alert is reported by the WatchdogHandler_A8140x (WDH) component when the external watchdog of the SBC is not working properly.
EPAS ECU SBC device watchdog is not able to reset the MCU at runtime.
EPAS full loss of assist.
This alert is reported by the IMCM_C0 component when Inter MCU Communication Manager (IMCM) Core1 takes more space in the generated CAN Frames than what is available. Core 0 and Core 1 are incompatible.
Core1 takes more space in the generated CAN Frames than what is available. Core 0 and Core 1 are incompatible.
EPAS full loss of assist.
This alert is reported if the number of resets is limited for the error causing reset. If the counter is greater than or equal to 5 then the SW does not perform reset but report this alert.
EPAS ECU maximum number of restart retries exceeded.
EPAS full loss of assist.
This alert is reported when CRC check failed, value of per-instance memory is other than the pattern or the actual per-instance memory value not equal to the saved per-instance memory value.
