5 TROUBLESHOOTING
This section provides instructions and guidance for G1000 system troubleshooting, as installed in the
Diamond Model DA 40.
Sections 6, 7 and 8 provide detailed instructions on equipment removal, replacement,
configuration, and return-to-service testing. Anytime a G1000 component or LRU is
removed, swapped, or replaced, the technician must follow the procedures given in
Sections 6, 7 and 8 to ensure proper operation of the system.
Troubleshoot the G1000 system by first identifying, then isolating the specific failure to the responsible
LRU. There are several indications that the G1000 presents to the pilot or technician, showing overall
system condition. A course of action should be determined based on the information presented on the
display. This section shows possible scenarios likely to be encountered during normal operation and
gives troubleshooting guidance to the technician to resolve problems.
Figure 5-1. System Status Page (AUX Group Normal Mode)
The 5
th
AUX group page on the MFD provides LRU health status by means of a green check or a red ‘X’.
Also, LRU software versions are shown along with other database versions and dates. If a red ‘X’ is
shown for an LRU, see the appropriate LRU troubleshooting section of this chapter for guidance.
Typically, the G1000 Alerting system provides alerts/annunciations in conjunction with the information
presented at the 5
th
AUX page.
