Modern vehicles rely on complex computer systems to monitor performance, emissions, safety, and drivability. When something goes wrong, warning lights and performance changes are often your first indication that your vehicle needs attention. Proper diagnostics are essential to identifying the root cause of the problem and avoiding unnecessary repairs.
At Shade Tree Garage, we use advanced diagnostic equipment and proven testing procedures to accurately determine what is happening inside your vehicle. Rather than guessing or replacing parts blindly, we focus on precise testing to find the true cause of the issue and recommend only the repairs that are needed.
Whether your check engine light has come on, your vehicle is running poorly, or you are experiencing unusual noises or warning messages, our diagnostic process is designed to give you clear answers and reliable solutions.
Our Diagnostic Services
- Check Engine Light Diagnosis: The check engine light can indicate a wide range of issues, from minor sensor problems to more serious engine or emissions concerns. Our diagnostic tools allow us to quickly retrieve and analyze fault codes, then perform follow-up testing to confirm the exact cause before any repairs are recommended.
- Performance Issues: If your vehicle feels sluggish, hesitates, idles roughly, or experiences reduced fuel efficiency, our diagnostics can identify underlying mechanical or electronic problems affecting performance.
- Electrical System Diagnosis: Today’s vehicles rely heavily on sensors, wiring, and computer modules. We diagnose electrical faults such as charging problems, intermittent failures, and malfunctioning components that can trigger warning lights or drivability issues.
- Brake System Diagnostics: ABS lights, traction control warnings, or unusual braking behavior may indicate electronic brake system problems. Our diagnostics help identify sensor failures or hydraulic control issues affecting braking performance.
- Transmission Diagnostics:
Transmission issues can involve electronics, sensors, or mechanical components. Diagnostic testing helps isolate shifting problems, slipping, or abnormal noises so repairs can be performed accurately and efficiently.
