A diagnostic test may usually be performed in a matter of minutes, but not everyone is aware of what is done during such a diagnostic. When you bring your vehicle to us, we will connect it to a system that uses software to access the computer processor, sensors, and microchips in your vehicle. The diagnostic test will tell us about the condition of your vehicle’s engine, such as ignition timing, engine build-up, fuel injector performance, ignition coil firing, engine rpm levels, air and coolant temperatures, airflow, crankshaft and camshaft position, throttle opening, transmission, exhaust system, brakes, and so on. We can identify any issue areas that require addressing during this diagnostic session.
