Cause
The G1000 has determined
the PFD needs service.
Solutions
•
Ensure the PFD connector is fully
seated and locked
•
If the unit was started in a very dark
environment the photocells may not
have enough light to initially raise the
CCFT level. Go to the GDU STATUS
page in configuration mode, ensure
CCFT CRNT 1 & 2 levels are above 50.
If the CCFT levels are not above
o
50, apply light to the photocell and
observe if the CCFT level rises.
If the CCFT level rises, disregard
o
the message.
If the CCFT level does not rise,
o
replace the PFD
•
Replace the PFD
•
If GDU software version is less than
6.01, check config module wiring for
faults and replace if necessary.
If issue continues, replace master
o
config module.
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.
