Diagnostic Trouble Codes
The System Fault screen is used to view and
clear DTC’s, which have been set.
Checking Diagnostic Trouble Codes
The System Fault screen contains a listing of all
of the Historic and Active DTC’s set within the
GCP system. If a DTC is stored in memory, the
screen will display that fault in the Historic Faults
column. If the fault condition currently exists, the
DTC will also show up in the Active Faults
column.
Opening Diagnostic Trouble Codes
To open a DTC, click on the DTC in the Historic
Faults column. A DTC Dialog Box will pop up on
the screen. The DTC Dialog Box contains the
following useful information:

If the fault occurred during the current
key cycle.

If the fault caused current engine
shutdown.

How many key cycles since the fault
was active.

Snapshot Data (explained later).

Flight Data Recorder (explained later).
The DTC Dialogue Box also allows you to clear
a single fault by clicking on the “Clear This Fault”
button and it allows you to clear all faults by
clicking on the “Click All Faults” button.
NOTE:
Record faults before clearing them. This
will aid in diagnosis.
Below is an example of a DTC Dialogue Box.
Snap Shot Data
The Snap Shot Data is a listing of specific
engine system variables. These variables are
recorded by the GCP at the instant the DTC
sets. By clicking on the “View Snap Shot Data”
button, a new window will pop up and you will be
able to view these variables. Here is an example
of a Snap Shot Data window.
