Frequently Asked Questions
What's the difference between a basic code reader and a professional scan tool?
A basic code reader from an auto parts store reads generic OBD2 codes but misses manufacturer-specific codes, live data streams, and bi-directional tests. Our professional scan tools access all vehicle systems, run active tests on components, and provide freeze-frame data for a far more accurate and complete diagnosis.
My car runs fine but the check engine light is on — do I still need a diagnostic?
Yes. A check engine light that's on even when the car feels normal often indicates an emissions issue, a failing sensor, or an early-stage problem that hasn't yet affected drivability. Ignoring it can lead to failed state inspections or a more serious problem down the road. A diagnostic gives you the facts you need.
Can you diagnose transmission problems with a mobile scan in McKinney?
Yes — our scan tools access the transmission control module (TCM) and can read shift solenoid codes, slippage data, and torque converter faults. While a full transmission rebuild requires a shop, diagnosing what's wrong and advising you on your options is absolutely something we do on-site in McKinney.
