Diagnostics

Modern vehicles rely on complex systems, sensors, modules, and electronics. A fault code alone does not always tell you what part has failed or what is actually causing the issue. Proper diagnostics require testing, experience, and the ability to interpret what the vehicle is doing.

At DSA Performance, diagnostics are one of our core specialties. We go beyond a basic scan to inspect symptoms, verify faults, and narrow problems down to the actual cause. That helps save time, avoid unnecessary repairs, and get your vehicle fixed correctly.

• Check engine lights
• Electrical issues
• Intermittent faults
• Misfires
• Rough idle
• Loss of power
• Starting issues
• Poor fuel economy
• Sensor and module faults
• Drivability concerns
• ABS, traction control, and warning lights
• Unresolved problems other shops have not fixed

If your vehicle has a recurring issue or a problem that keeps coming back, proper diagnostic testing is often the most important first step.
