Our Diagnostics Service
Automotive diagnostic services are essential for identifying issues in your vehicle’s engine, transmission, brakes, electrical system, and more. Using advanced diagnostic tools and equipment, we can connect to your car’s onboard computer system (ECU) to retrieve diagnostic trouble codes (DTCs) and analyze data from various sensors and systems. This helps pinpoint problems, from minor glitches like a faulty sensor to major mechanical or electrical failures.
By performing a thorough diagnostic, we can offer an accurate repair plan, potentially saving time and preventing further damage to your vehicle. Regular diagnostic checks are important when the check engine light comes on or if you’re experiencing unusual performance or sounds from your car.
When Is A Diagnostics Appointment Right For My Vehicle?
A diagnostic appointment is right for your vehicle when you’re experiencing issues that could be related to the engine, transmission, electrical system, or other major components of your car, and you’re unsure of the cause. Our experienced technicians recommend coming in to see us if your vehicle has any of the following issues (and more!):
- Check Engine Light Comes On: That dreaded light – the check engine light! If it turns on, it’s a clear indication that something in your vehicle isn’t functioning properly. A diagnostic test can help identify the error codes and give insight into the problem.
- Poor Engine Performance: If your car is running rough, misfiring, stalling, or hesitating during acceleration, a diagnostic test can reveal issues with components like spark plugs, sensors, or the fuel system.
- Unusual Noises: Strange noises like grinding, knocking, or whining can signal mechanical or electrical issues. One of our trained technicians can help pinpoint the issue and get your vehicle back up and running.
- Reduced Fuel Efficiency: If you notice a sudden drop in your fuel economy – having to fill up more often than you used to after making the same trips – it could be due to issues with the engine, sensors, or fuel system, which a diagnostic service with one of our technicians can pinpoint.
- Electrical Issues (Lights, Windows, or Radio): When your window decides not to roll up or down, your radio quits working, or the lights start flickering – it’s time to give us a call to help diagnose the problem.
