What triggers it
Interruption or short to GND of a monitored ECU internal enable line. After the failsafe logic test has finished the ECU internal enable lines are monitored. It is expected that the enable lines always stay at high level (except the SW intends another state). If this is not the case this fault is logged.
When it clears
No internal issue is detected after changing operation cycle. If the condition persists, the DPB module may require replacement.
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.
