This section provides information to assist troubleshooting if fault codes are displayed on the GDU or
problems occur after completing system maintenance. See Appendix A of this document retained in the
aircraft permanent records for a list of the interfaced equipment and system configuration data. When
troubleshooting the G500/G600 TXi system, refer to wire routing drawings and interconnect diagrams
retained in Appendix A of this document or with the aircraft’s permanent records.

4.1 General System Troubleshooting

Before troubleshooting the G500/G600 TXi system, use the Configuration log tool to print the current
configuration log to ensure that system configuration settings match those recorded in the aircraft’s
permanent records.

If the current aircraft configuration does not match the configuration log retained with the aircraft
permanent records, load the saved configuration from the SD card retained with the permanent aircraft
records. If this cannot be accomplished, or does not correct the configuration, the configuration must be
corrected by a Garmin dealer using an installer unlock card and the configuration instructions provided in
Section 5 of the G500/G600 TXi Part 23 AML STC Installation Manual (P/N:190-01717-B3). Basic
troubleshooting of the G500/G600 TXi system can be accomplished using the instructions provided in
Table 4-1.
