Description

Continuous monitor of enable lines detected a missing(low) enable signal.

Cause

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.

Clear condition

No internal issue is detected after changing operation cycle. If the condition persists, the DPB module may require replacement.
