What is a Car Diagnostic Test & Why is it So Important?

Annual checkups from your physician keep you in good health, right? Well, the same goes for your car-regular diagnostic tests can detect problems with your vehicle before they require expensive repairs, or worse, leave you stranded on the side of the road after a breakdown.


When your check engine light comes on, it’s usually an indication that there’s a serious problem with your car’s ignition, fuel, or emission system. As soon as you see your check engine light illuminated on your dashboard, call General Auto Repair for an immediate car diagnostic.

Similar to the way doctors use medical testing to identify health issues, our mechanics use a computer diagnostic to determine the problem with your car. Once we scan your vehicle’s on-board computer and retrieve the Diagnostic Trouble Codes, we will work to diagnose the malfunction. From there, we’ll determine what repairs are needed to prevent engine damage and get you back on the road safely.
