## Discrepancy

(CAN) DURING CRUISE THE ENGINE 2, ENGINE DRIVEN HYDRAULIC PUMP LOW PRESSURE LIGHT ILLUMINATED.  THE ENGINE 2 IDG DRIVE LIGHT ALSO ILLUMINATED.  THE CREW CARRIED OUT AN AIR TURN BACK.  MAINTENANCE CARRIED OUT A FUNCTION CHECK OF THE ENGINE DRIVEN HYDRAULIC PUMP AND COULD NOT FAULT THE SYSTEM.  THE IDG DRIVE LIGHT TROUBLESHOOTING DROVE THE REPLACEMENT OF THE IDG BUT THE FAULT STILL REMAINED.  A FAULT WAS FOUND WITH THE IDG HARNESS. A NEW HARNESS WAS ORDERED AND WILL BE INSTALLED PRIOR TO RETURNING THE ACFT TO SERVICE.
