When your check engine light comes on a trouble code is stored in the computer. Some codes are universal and can be read by most scanners. Other codes are stored more deeply in memory or are proprietary to the vehicle make. For these kinds of codes, your service center has powerful, and expensive, equipment and software to help them read and retrieve trouble codes. At Accu Auto Care LLC in Maugansville we install quality NAPA replacement parts. Give us a call at 301.665.9180 and let us help keep you safely and economically on the road.
