4.3.2 Control Unit
Control Unit screen displays all controllers available of the vehicle
manufacturer. The controllers listed on the menu do not mean that they are
installed on the vehicle. It is useful for technicians who are familiar with the
vehicle specifications.
To select a system for testing:
1.Press Control Unit from the menu and a controller menu displays.

4.4 Diagnostic Operations
After a system is selected and the scanner establishes communication with
the vehicle, the Function Menu displays. Generally the menu options are:
● ECU Information
● Read Codes
● Freeze Frame Data
● Erase Codes
● Live Data
NOTE
Not all function options listed above are applicable to all vehicles. Available
options may vary by the year, model, and make of the test vehicle. A “The
selected mode is not supported!” message displays if the option is not
applicable to the vehicle under test.
4.4.1 ECU Information
ECU Information screen displays the identification data of the control module
under test, such as the control module identification string and the control
module coding.
To read ECU information:
1.Press ECU Information from Select Diagnostic Function menu.
28

2. A screen with detailed information of the selected control module displays.
Figure 4-18 Sample ECU Information Screen
3.Press function key Save to store ECU information, and press Print to print
the information. Or use the ESC button to exit.
4.4.2 Read Codes
Read Codes menu lets you read trouble codes found in the control unit.
Typical menu options include:
● Present/Permanent/Current Codes
● Pending Codes
● History Codes
● Code History
● Self Diagnostic
Present/Permanent/Current codes stored in a control module are used to
help identify the cause of a trouble or troubles with a vehicle. These codes
have occurred a specific number of times and indicate a problem that
requires repair.
29
Automotive Diagnostic System GT80_English_V1.00
Pending codes are also referred to as maturing codes that indicate
intermittent faults. If the fault does not occur within a certain number of drive
cycles (depending on vehicle), the code clears from memory. If a fault occurs
a specific number of times, the code matures into a DTC and the MIL
illuminates or blinks.
History codes are also referred to as past codes that indicate intermittent
DTCs that are not currently active. Code history is number of engine starts
since the DTC(s) were first detected (to see if they are current or
intermittent).
Self diagnostic lets you manually activate system tests that check for DTCs.
Usually it includes a KOEO (Key-on, engine-off ) test and a KOER (key-on,
engine-running) test.
To read codes from a vehicle:
1.Press Read Codes from Select Diagnostic Function menu. A code list
including code number and its description displays.
Figure 4-19 Sample Function menu screen
2.Slide up and down to view additional information when necessary.
3.Press Save to store DTC information, and press Print to print the code
information. Or use the ESC button to exit.
4.4.3 Freeze Frame Data
Freeze Frame Data menu displays freeze frame data, a snapshot of critical
vehicle operating conditions automatically recorded by the on-board
computer at the time of the DTC set. It is a good function to help determine
what caused the fault.
To view freeze frame data:
1.Select Freeze Frame Data from Select Diagnostic Function menu. Details
of freeze frame data displays.

2.Slide the screen up and down or use the PAGE UP and PAGE DOWN
button to view additional information when necessary.
3.Press function key Save to store freeze frame information, and press Print
to print the freeze frame data. Or use the ESC button to exit.
4.4.4 Erase Codes
Erase Codes menu lets you to clear all current and stored DTCs from a
selected control module. Also it erases all temporary ECU information,
including freeze frame. So make sure that the selected system are
completely checked and serviced by technicians and no vital information will
be lost before clearing codes.
NOTE
● To clear codes, make sure that the ignition key is switched to ON with the
engine off.
● Erase Codes does not fix the problem that caused the fault! DTCs should
only be erased after correcting the condition(s) that caused them.
To clear codes:
1.Press Erase Codes from Select Diagnostic Function menu.

2.Follow the on-screen instructions and answer questions about the vehicle
being tested to complete the procedure.

3.Check the codes again. If any codes remain, repeat the Erase Codes
steps.
4.4.5 Live Data
Live Data menu lets you view real time PID data in text, plot and gauge
formats, learn good sensor data and compare them with faulty data, and
record live data from a selected vehicle electronic control module.
Menu options typically include:
32
Automotive Diagnostic System GT80_English_V1.00
● All Data
● Custom List
4.5.5.1 All Data
All Data menu lets you view all live PID data from a selected control module.
GT80 allows you to view live data information in 6 differenct types of display
modes.
● Text Mode - this is the default mode which displays the parameters in
texts.
● Graph Mode - displays the parameters in waveform graphs, giving you
the ‘real picture’ of what’s going on in the vehicle. You can view up to 4
parameter graphs simultaneously and easily find and zoom in on a
particular string of data.
● Merged Graph Mode - merges multiple PID plots into one coordinate, so
you can easily see how they affect each other, providing you with the
most comprehensive and functional look at live data possible.
● Guage Mode - displays the parameters in the form of an analog meter.
● Study Mode - gives you the ability to learn good live sensor data values
during idle, KEKO, acceleration, deceleration, part load and heavy load
on each vehicle comes into your shop and records them for future
reference.
● Comparison Mode - If that vehicle comes in is with a problem, you can
easily compare the faulty sensor and parameter readings to the good
readings, and you will be alarmed when a faulty sensor reading is
detected.
NOTE
● Study and Comparison modes are available for viewing of parameter
readings in text mode ONLY.
● In case no learned value is stored in the scan tool, the Comparison Mode
will not be available.
To view all live PID data:
1.Press Live Data from Select Diagnostic Function menu to display the live
data menu.

2.Press All Data from the menu to display the data stream screen. All
readings will be displayed in text format by default.

4.To move a data line to the top of Data List screen, just tap the line to select
and then press the button To Top. To record live data to memory of the
scanner for offline review, just tab the button Record, and press Stop to
stop recording at any time. To print the data through computer, tap the
Print icon.
5.To view live PID in graph format, press the tab Graph, and 4 PID plots
display. To view another PID plot, tab the name of a plot and a list of
available PIDs display. Select one from the dropdown box and the plot
changes to the newly selected PID. To view the plots with more details, use
the Zoom in button; instead, use the Zoom out button.

6.To see how the PIDs affect each other, press the Graph Merge tab to
merge them into one coordinate for easy and intuitive diagnosis.
