2.11.2.3 Downloading GIA and GSA Maintenance Logs
f additional assistance is needed troubleshooting autopilot faults, the Maintenance logs can be
I
downloaded to an SD card as a text file (.txt) and emailed to Garmin Aviation Product Support at
avionics@garmin.com. Please call Garmin Aviation Product Support before you send a Maintenance Log
to notify them you are sending it to prevent a delay in response. You may download multiple GIA and
GSA Maintenance Logs to the same file, however in your email to Garmin you must furnish the order in
which they were downloaded (i.e. GIA1, then GIA2, then SRVO PTCH MON, then SRVO PTCH CTL,
etc.).
1. Insert a FAT 32 formatted SD card into the top slot of the PFD before turning on the displays.
2. Power up PFD and MFD in the configuration mode.
3. On the PFD in the System page group, use the small FMS knob to scroll to the Diagnostics Terminal
page.
4. Press the LG2CRD softkey at the bottom of the PFD. Verify that the softkey text grays out. This
indicates the recording function is active and all text that is displayed in the OUTPUT window will be
saved to the card.
5. Enable the curser by pressing the FMS knob, select either "GIA1" or "GIA2" in the LRU drop down
menu and then press the ENT key to select it.
6. Servo Fault logs can be retrieved if needed by moving the cursor to the SERVO box and selecting the
servo you need to access using the small FMS knob to activate the drop down list and press the ENT key.
Be sure to download both the Monitor and Control Logs for that servo.
7. 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".
8. Press the LG2CRD softkey to turn off the recording function.
9. Wait 1 minute for the system to save the data from the download to the SD card. As the data is being
saved to the SD card, record the order of the LRU's and/or Servos that were downloaded. Provide the
information to Cessna or Garmin to help decipher the order of the error data.
10. Power down the G1000 System and remove the SD card.
11. Insert 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 data.
12. 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.
