WHEN SOMETHING INTERNAL DOES NOT OPERATE AS EXPECTED...
the technology illuminates the check engine light and stores the onboard diagnostic (OBD) codes your auto repair professional will use to help pinpoint the underlying issue.

A code reader is needed to access the codes from the vehicle’s computer. Your local auto repair shop or auto parts store typically offer code reading services, or you may have your own code reader to complete this step yourself.
The latest generation of codes (OBD II) are the same for all cars. Each code consists of a five-digit alphanumeric string beginning with the letter P.

Diagnostic Code Translator
Once you have obtained the codes, use the Diagnostic Code Translator tool below to get more information about the issue your car may have. These codes provide the vital clues your auto repair professional will need to identify potential causes of the problem.
Informed Consumer
Diagnostic trouble codes do not automatically mean you will incur an expensive repair. Often a cleaning or part replacement, a new filter or spark plugs, or changing a faulty belt or wire will resolve the issue. The trained technicians and mechanics at AAA Approved Auto Repair shops can assist with your car services and help you avoid spending money on parts and repairs your vehicle may not need.

Check Engine Light
If your check engine light illuminates, take your car to your nearby auto repair shop for evaluation. While immediate service may not always be necessary, it is recommended that you do seek the assistance of your automotive professional as soon as possible to avoid a worsening problem.

If your check engine light flashes while you are operating the vehicle, continue to the nearest safe location. This system alert signifies an issue requiring immediate service.
