Solutions
•
Load GMC configuration files.
•
Replace GMC.
•
If problem persists, replace
master configuration module,
check config module wiring for
faults and replace if necessary.
NOTE
New Terrain/Obstacle cards,
Jeppesen Aviation Database and
other optional features (i.e.
TAWS unlock card) will need to
be replaced if the master
configuration module is changed.
The G1000 System ID number
will change to a new number
when installing a new master
config module. The old Terrain
and other cards will no longer
work as they will remain locked
to the old System ID number.
•
Check wiring for faults (ref Failed
Path troubleshooting section 5.7).
•
Replace the GMC 710.
•
Load the correct software version.
See Section 3.9 for the Software
Load Procedure.
