Diagnostics
As described in Chapter 5 - Components and Functions (Theory), the service platform uses a web-
based user interface (UI) to provide access to common service components. A service dongle (part 
number 066E0703) is required to access areas proprietary to GE.
The Diagnostic home page displays a listing of test categories consisting of Acquisition Diagnostics, I/
O Devices and Common Diagnostics. Expand the desired main category to select groups or individual 
tests.

Acquisition Diagnostics
Acquisition Diagnostics is one of three main headings under the GSUI Diagnostics Tab. Figure 7-14 
shows the top level menu choices under Acquisition Diagnostics. The subheadings and their respective 
diagnostic/troubleshooting menu choices are called out and described in the sections that follow.

Section 7-7      Acquisition Diagnostics (cont’d)
Individual selections run several diagnostics in a  Bottom-up Confidence-Building Order and return 
status information identifying any problems. The Acquisition Diagnostic menu is structured as follows:
7-7-1 Automatic Troubleshooting 
-  Runs  all diagnostics and analyzes  the results  to isolate to  the  faulty  FRU.
- This is the  BEST way to diagnose a problem with the system.
- Takes less than  6 minutes for all tests to run.
- Disconnect all probes from the scanner before executing the Automatic Troubleshooting  sequence.
The choices for Automatic Troubleshooting, shown in  Figure 7-16 on page 7-16 , allows for running all 
acquisition diagnostics under the selection Troubleshoot All Acquisition Hardware. Figure 7-15  Customer Acquisition Diagnostics

When you select a test to run, like  Troubleshoot all Acquisition Hardware , the display changes as shown 
in  Figure 7-18 on page 7-18  .
1.)  Instructions  Frame
- Displays either a test-specific text or the default instructions.
2.)  Status  Frame
- Initially displays the last known status for a selected diagnostic. Once the diagnostic starts,  the frame displays the “current” status of all test results.
- The Status Frame also contains the user interface elements used for Diagnostic Control and  Operator Feedback.
3.)  Execute  Button
- This switch has two modes - each with appropriate text:
- Execute - to start the diagnostic
- Abort - to stop a diagnostic

4.)  Loop Count
- This is an editable text field that will only accept numeric values of 4 digits or less. When the  switch is configured as an “execute” switch and pressed, the loop count field will be queried 
to determine the number of times to execute the diagnostic.
5.)  Progress  Indicator
- Displays a graphical progress indicator for the user.
6.)  Short  Text  Message
- Displays brief messages about the test’s progress during execution.
7.) Status  Frame  Background Color
- Initially gray, the Status Frame background color changes upon completion of a diagnostic to  indicate completion status.
- Code Status Fail = Red
- Code Status Pass = Green
- Code Status neither Pass nor Fail (Example: Aborted) = Gray (default color).
7-7-2 Reliability Testing
Overnight relialibility test.
- Runs all diagnostics. Logs  ALL
 results. Results accumulate in the log each time the tests are 
run. The log file continues to grow.
NOTE: This is not intended for field service use. Typically a manufacturing test.
