|
Dual Power Pump (DPP) ECU memory recoverable corruption detected.
|
One DPP ECU memory buffered data table is corrupt
|
Steering assist may be affected
|
|

CAN messages from the steering speed ECU have an invalid counter value, indicating an error in data integrity has been detected.
|
10 or more CAN message frames from the steering speed ECU have counter values that do not increment as expected
|
Steering assist may be affected, since the steering speed to Dual Power Pack (DPP) interface is interrupted
|
|
|
Expected CAN messages from the steering speed ECU were not received.

|
|
|
SPI transfer to Bridge Driver ASIC failed.
|
Transfer Error (error frame, wrong address. timeout, CSIH error) is logged if a SPI alert is detected by ASIC or uC.
|
System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.
|
|
|
Internal bridge driver ASIC hardware defect detected.
|
B6AsicFault Internal bridge driver ASIC hardware defect detected.
|
System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.
|
|
|
System ASIC internal oscillator alert is detected.
|
System ASIC internal oscillator doesn't work correct (too low or too high frequency), uC is monitoring SPI register bit OSCfail_set_FF every specified time and the alert is confirmed when this alert bit is set for longer than 80ms.
|
System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.
|
|
|
ASIC Init test failed during init task.
|
Defect in the System ASIC, the alert detection function in the ASIC doen't work. uC sends some alert test frames (address error, parity error, clock error) and evaluate the responses. The tests pass if the ASIC could detect the alert and set corresponding alert flags.
|
System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.
|
|
|
System ASIC CLKIN alert is detected.
|
System ASIC CLKIN input signal is outside of the specified frequency range, uC is monitoring SPI register bit CLKIN_fail_SPI every specified time and the alert is confirmed when this alert bit is set for longer than specified time.
|
System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.
|
|
|
