0x027507 Controller #1-Mechanical System Not Responding Or Out Of Adjustment

What you'll see
Symptom:
System reaction
SystemReaction: No user function restricted BUT failure causes permanently awake EBS ECU that may drain vehicle's battery.
Diagnostic depth
Detection: This fault could be set in multiple scenarios. Either there is a problem with the shutdown process itself (internal SW error), or there is an external reason (HW failure, unexpected CAN communication from other ECUs) which prevents the ECU from reaching sleep mode. The two cases can be distinguished based on additional data.
Cause: Unexpected CAN traffic from other ECUs if CAN wakeup is applicable/HW failure/internal SW error
