Diagnostics
This option reads the Diagnostic Trouble Codes (DTCs) from your vehicle engine. You can also erase these codes from here.
To look up the DTC codes, the following website is very helpful:
http://engine-codes.com/
You can also search for more information about DTC codes online using your favorite search engine.
Show Settings
The Show Settings screen will show you information about your vehicle, the GT, and your current vehicle settings. This screen will also indicate if
the GT tune is currently installed or not installed on a vehicle.
Uninstall GT
This option will allow you to uninstall the tune from your vehicle. This process is very similar to installing the tune, so be sure to take the same
precautions listed on pages 33-34.
You can find more information about uninstalling the download on pages 43-45.
Update GT Software
This option will update the software on the GT itself from the files on the Micro SD card. This is an important final step to the update process. See
pages 20-27 for more information about updating your GT.
IMPORTANT NOTE: Most DTCs indicate a problem with the engine, not with the tune or the tuner itself. If you want to know if a DTC is being caused by the GT or not, unin-
stall the tune and drive your vehicle for about one week. If the DTC comes back, there is a problem with the vehicle and you should take it to a trusted mechanic. If the DTC
doesn’t come back, reinstall the tune and test drive for another week – if the DTC comes back while the tune is reinstalled, contact technical support. Be sure to have your
tuner, vehicle, and a computer with internet access available when contacting technical support. See page 65 for more information about contacting technical support.
