Possible root of alarm is poor contact in one of control system switches terminals or faulty switch. For example there is a recorded issue with M/E control pressure switch abnormal electric signal which caused activation of "M/E control system" alarm. The solution in such cases is to trace the faulty switch and replace it with new or change over to back-up.
