Computer Diagnostics

If you have a check engine light on, or if your car is running as it should, computer diagnostic is an efficient and cost effective way to get at the heart to problem.  All modern cars are controlled by special computers that continually monitor the health of your vehicle.  This onboard computer system knows and monitros hte perating parameters of every component in the cars engine.  When it sees a signal that is outside normal limits, or fails to see an expected change in a signal, it store a diagnostic trouble code, and if the code is sever enough, alerts the drive by illuminating the check engine light.

Our highly trained professionals know how to read and interpret those diagnostic trouble codes to quickly execute cost effective repairs when necessary.  To access these codes our technicians connect a scanning tool to the cars diagnostic link connector .  This tool displays any codes that have stored by the computer.

Sometimes the codes are set even though there is nothing wrong with the system.  This happens when a mechanical problem, like an engine vacuum leak, creates operating conditions that cause system components to generate signals outside their normal range.  So to pinpoint a problem, our highly trained technicians starts with the code and then would perform additional test to narrow down the source.  These tests can range from mechanical checks, like engine compression, to in-depth electronic diagnosis or monitoring real-time signals with the scanner itself.
