7. Move the cursor back to the LRU box, select "GIA2" in the LRU drop down menu and
then press the ENT key to select it.
8. Skip the SERVO box and move the cursor to the COMMAND box and select "View
Maintenance Log" in the drop down menu then press the ENT key. The error log data
will be displayed in the OUTPUT box. If you see the "more...press any key to continue"
text at the bottom of the screen, you may need to reselect "View Maintenance Log" for
GIA data to allow it to continue scrolling down the screen (pressing any key will not
continue, disregard the text instruction you to do so). Continue to scroll through all the
OUTPUT data until you see the text, "End of Fault Log".
9. If you need to download Servo fault logs (usually done at the request of Garmin Product
Support), perform the following steps. Otherwise, skip to step 10.
a) In the LRU box, you may select either "GIA1" or "GIA2".
b) In the SERVO box, choose a servo using the FMS knobs. Each servo contains
two logs, one in the Monitor (MON) processor and one in the Control (CTL)
processor. You must download both for each servo separately.
c) In the COMMAND box, select "View Maintenance Log" and press the ENT key.
d) The log will appear in the OUTPUT box. It will scroll to the end automatically.
When it is complete, repeat steps a-c for the other servos in the aircraft. Be sure
to note the order the servos were downloaded in including the Monitor or Control
logs to email to Garmin Product Support. Without knowing the order in which the
logs were downloaded, Garmin will be unable to process them and will ask for
another full download.
10. Press the LG2CRD softkey to turn off the recording function.
11. Wait 1 minute for the system to save the data from the download to the SD card.
12. While you are waiting for the data to be saved to the SD card, record the order of the
LRU's and/or Servos were downloaded so that you can provide that information to
Cessna or Garmin to help decipher the order of the error data.
13. Power down the G1000 System and remove the SD card.
14. Insert the SD card in the card reader of a laptop or desktop computer and open the
"diag_buf_log.txt" file from the SD card using the WordPad program. Verify that all of the
fault logs were downloaded by checking for the "End of Fault Log" message at the end of
the GIA data, and that the last servo log entry has the current date.
15. Insert the fault log as an attachment to an email and include the LRU order how the data
was downloaded and send to Garmin Aviation Product Support at
avionics@Garmin.com.
