The Predator Diablo Tuner installed in a vehicle can be used to perform diagnostic tests to ensure that the vehicle is working properly. Since the Diablo Tuner has an easy-to-use digital display, you can determine how your car is running with a few simple button presses.
Turn your Diablo Tuner on. Select the "Diagnostics" option on the tuner's main menu.
Select the "Show Trouble Codes" option to view a list of the current issues with your vehicle. You may need to consult your manual to determine which problems go with the displayed trouble codes.
Select the "Clear Trouble Codes" option to clear the current log of trouble codes. Select the "Real Time Data" option to view the current state of your vehicle.
Connect your Tuner to a computer using the included USB cable, then select the "Real Time Streaming" option to send real time data from the tuner to your computer. The computer will log this information on its hard drive.
Select the "Log Play Back" option to view all of your vehicle's past data on the tuner's digital display.
