4 TROUBLESHOOTING

This section provides instructions and guidance for G1000 system troubleshooting, as installed in the
Columbia 350/400.
Sections 5, 6 and 7 provide detailed instructions on equipment removal, replacement,
configuration, and return-to-service testing, respectively. Anytime a G1000 component
or LRU is removed, swapped, or replaced, the technician must follow the procedures
given in Sections 5, 6 and 7 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.
