Alerts

ECU internal electrical enable line has either a short to GND or cannot be switched on by the micro controller and the system chip. Initial test of the ECU internal electrical enable line detects that enable line cannot be switched on by the software.

System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.

Erroneous safety logic (The clockin monitor of the system IC reports wrong clockin alert status to the uC). This alert is logged if the feedback to the uC does not show the expected clockin alert state.

System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.

Erroneous safety logic (BIST of system IC does not switch off electrically after too much received wrong BIST commands), The failsafe logic test tests that after 3 wrong BIST commands the BIST alert counter counted up to its max. value and that the BIST state machine switches off electrically consequently.

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 chip internal decouple bits are not reset within the expected time. The failsafe logic test sets the hydraulic and electric decouple bits of the system chip.

System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.

MRG is either always switched ON or Not able to Switch OFF when Hydraulic Enable or MRA control is pulled LOW.

System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.

A flash error like an incorrect checksum or single error overflow is 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.

The bandgap voltage measured by the Analog-to-Digital Converter (ADC) is not within specification. This can be due to an issue affecting the ADC.

System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.

DMA channel or module could not be suspended or aborted until timeout threshold, The monitoring is a continuous monitoring of DMA/DTS transfer errors due to timeouts.

System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.

The valve overheat protection is enabled. This can happen when the valves actuate for too long in diagnostic mode.

System will be running with full assistant for driver brake request.

High pressure is created in the system due to eg: plunger movement in diagnostic mode. Alert is set in diagnostic mode, when high pressure is built up within Hydraulic Unit.

System will be running with full assistant for driver brake request.

Alert is set when a stop protocol callback is called from stack and no protocol is active.

System will be running with full assistant for driver brake request.

In case of a CPU exception, an alert is reported and the system is degraded accordingly.

System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.

The voltage at the charge pump is less than expected.

System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.

Capacity of charge pump buffer or performance of charge pump is not sufficient.

System will be running in fully degraded state. Braking may require increased effort. Hydraulic Boost Compensation will be triggered when driver pressed brake pedal.

The added voltages of the Decoupled Power Brake (DPB) BLM temperature sensors have no constant value.

System will be running with internal degraded pedal map. Braking may require increased effort.

The Decoupled Power Brake (DPB) BLM temperature sensor 2 is shorted to ground.

System will be running with internal degraded pedal map. Braking may require increased effort.

The Decoupled Power Brake (DPB) BLM temperature sensor 2 is shorted to supply.

System will be running with internal degraded pedal map. Braking may require increased effort.
