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

After the failsafe logic test has finished the status of the watchdog or rather the safety logic is being continuously monitored. If the status is not as expected this fault is logged.
Clear condition
No internal issue is detected after changing operation cycle. If the condition persists, the DPB module may require replacement.
