## Discrepancy

EN ROUTE, THE CREW RECEIVED A PROXY SYSTEM FAIL INDICATION ON THE HYDRAULICS PAGE AND CALLED MAINTENANCE CONTROL.  THE CREW FOLLOWED THE QUICK REFERENCE HANDBOOK AND WERE INSTRUCTED TO DIVERT TO PIT.  MAINTENANCE INSPECTED AND FOUND SEVERAL CODES IN THE PSEU.  MAINTENANCE THEN REPLACED THE PSEU IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 32-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
