DTC Scan

Turn off That Check Engine Light!

The ScanGaugeIII can check for Diagnostic Trouble Codes (DTCs) and if found, can display how many there are and the Trouble Codes themselves along with the code meaning. You are also able to view pending codes if there are any to catch problems before they become worse. The ScanGaugeIII can scan your vehicle for emissions readiness and let you know what if any tests have not passed before you take your vehicle in for emissions testing.


Is Your Vehicle Ready for Emissions Testing?

Some states now require that before running emissions checks, the vehicle self-tests have to be completed and cleared. The ScanGaugeIII reports this “Readiness” and what tests may not have passed yet.

Read & Clear Pending Trouble Codes

If no codes are found and your Check Engine light is still on, your vehicle may be storing pending codes. The ScanGaugeIII provides a method to force clear any detected or undetected Trouble Codes with just a few touches of the screen.
