|
|
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. 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.
|
|
|
This alert is reported by the ActuatorManager_R12 (AM) component when there is a GDU failure. Bootstrap capacitor short detection or GDU internal rail undervoltage check.
|
EPAS ECU GDU device monitor detected failure (capacitor short detection or internal rail undervoltage).
|
EPAS full loss of assist.
|
|
|
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.
|
|
|
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 when there is a SW systematic failure, faulty error reporting in one of the components (report and error with not supported errorId).
|
EPAS application component ErrorReactionManager detected invalid error message (wrong errorId or messageKind).
|
EPAS full loss of assist.
|
|
|
This alert is reported by the ErrorLogger (ERL) component when the internal general error logging buffer overflowed.
|
