Check engine light on your dashboard? Our free Diagnostic Trouble Code service will use the latest in scan tool technology to pull the codes that are causing your check engine light to trigger.

Nothing can be more frustrating than the unknown of a check engine light. Our free service will use the latest in scan tool technology to pull the codes that are causing your check engine light to trigger. The information we are able to pull will be presented to you with an explanation of services, or further diagnostic testing, needed to correct the issue. Many engine trouble codes can have multiple causes and may require further diagnostics to find the root of the problem. If our trained technicians feel that the code is present in error, i.e. the gas cap was loose, we can reset the light for you at no charge. Our Diagnostic Trouble Code service at Dunn Tire includes the following

  • A scan of your vehicle's on-board computer using state of the art equipment
  • Documentation of the diagnostic trouble code(s) (DTC) and code description(s)
  • A database check for any technical service bulletins issued by the vehicle manufacturer that may be related to the DTC(s)
