Garmin G1000 Lru Replacement/Configuration & Testing; Gdu 1050A/1550 Pfd & Mfd - Garmin G1000 Nxi System Maintenance Manual

7. Garmin G1000 LRU Replacement/Configuration & Testing
This section provides procedures to be followed after a piece of G1000 equipment is replaced.
At the beginning of each LRU section, instructions are given to guide the technician for various
removal/replacement scenarios. These instructions define necessary procedures to be followed
for situations where original equipment was reinstalled as well as for situations where new
equipment (new serial number) is installed.
Garmin recommends the use of SanDisk brand SD cards to load G1000 software
and configuration files. If another brand of card is used, and software loading
problems occur, replace the card with a SanDisk brand card and reattempt the
software load.
Connect a ground power unit to the aircraft for software loading. DO NOT
RELY ON THE AIRCRAFT BATTERY TO LOAD SOFTWARE. DO NOT USE A
BATTERY CHARGER AS AN EXTERNAL POWER SOURCE DUE TO
ELECTRICAL NOISE IT MAY INJECT IN THE G1000 SYSTEM.
ALLOW POWER TO BE REMOVED FROM THE SYSTEM WHEN LOADING
SOFTWARE! Remove power only when told to do so by the following
procedure. Power loss during a software upgrade may cause a LRU to become
corrupted and unresponsive requiring replacement. Remove power only when told
to do so in the procedure.
All displays should be in the same mode (configuration or normal), unless
instructed differently.
If an incorrect configuration file is loaded at any time in this section, STOP
and start the configuration load over using Section 3.8.
GDU 1050A/1550 PFD & MFD
Original Display Reinstalled
If the removed display(s) are re-installed in their original positions, no software or configuration
loading is required. This does not include units that were returned for repair as their software
and configuration files are deleted during the repair testing process. Continue to the PFD/MFD
Test procedure, Section 7.1.7.
Original PFD Displays Installed in Opposite Locations for Troubleshooting
If the PFD 1 and PFD 2 are installed in opposite positions, no software or configuration loading
is required. Continue to the PFD/MFD Test procedure, Section 7.1.7.
New Repair or Exchange Display(s) Installed
If a new, repaired or exchanged GDU is installed, the correct software and configuration files
must be loaded to the unit.
