Later the aircraft was enroute at FL310 about 290nm northeast of Calgary when LNAV and VNAV autopilot modes were unavailable and the crew was unable to view the flight plan waypoints in the FMS. The crew declared emergency and returned to Calgary for a safe overweight landing about 100 minutes after departure.

The Canadian TSB reported maintenance replaced a faulty TAT probe and an air/ground relay as per Aircraft Maintenance Manual.
