Your vehicle is equipped with dozens of interconnected systems, each playing a critical role in its performance and safety. When something goes wrong, today’s advanced technology gives us the tools to diagnose the problem quickly—if you know how to interpret the data. That’s why professional diagnostic services are so important. A flashing warning light on your dashboard can indicate anything from a loose gas cap to a serious engine malfunction. Without the right equipment and expertise, it’s nearly impossible to tell the difference. At Mary Street Garage, we offer comprehensive diagnostic services in Bethlehem, PA to identify the issue accurately and recommend the best repair options.

Delaying diagnostics can lead to more severe damage and significantly higher repair costs. A minor sensor failure might reduce fuel efficiency, while an ignored check engine light could eventually result in major engine problems. Our ASE-certified technicians are trained to read and interpret vehicle computer systems using industry-leading diagnostic tools. We go beyond code reading—our team conducts a full inspection to confirm the issue, rule out false positives, and explain what’s going on in simple terms. We never recommend unnecessary repairs, and we always focus on transparency and long-term value. With regular diagnostics, you’ll stay ahead of issues, reduce unexpected breakdowns, and enjoy better performance from your vehicle.
