How can I check for Diagnostic Trouble Codes (DTCs) using my Innova 3011?
Connect the Code Reader to the DLC, turn the ignition on without starting the engine, and use the DTC button to scroll through LCD display for multiple DTCs. If issues arise, refer to the status indicator LEDs and icons for further guidance.
