Message Description:
The Electronic Flight Display Unit (EFDU) shows data that does not agree with the initial sensor data.
NOTE: This message is applicable to all EFDUs with faults (one of which can be a Primary Flight Display (PFD)). If two PFDs (usually EFDUs 1 and 6) have faults at the same time, the Engine Indicating and Crew Alerting System (EICAS) display shows CHECK PFD.
Possible Causes:
- Display Unit 6 (DU) (M12)
- Integrated Avionics Computer 1 (IAC) (A11)
- Integrated Avionics Computer 2 (IAC) (A10)
- Integrated Avionics Computer 3 (IAC) (A12)
- Associated Wiring
Troubleshooting Tips:
Advisory Wire/Service Bulletin:
- AW000-31-0043 - Honeywell Display Unit DU-875 End of Production
- AW700-31-0527 - Display Unit Honeywell Primus (DU-870) Support
