Frequently Asked Questions
Straight answers about car diagnostics in Toowoomba
What does a car diagnostic test actually check?
A full diagnostic scan checks your vehicle's engine, transmission, ABS, airbag and emissions systems by reading fault codes stored in the onboard computer, then interpreting what they mean for your specific vehicle.
Why is my check engine light on?
It can range from something minor, like a loose fuel cap or a failing sensor, to something more serious like an emissions or engine fault. The only way to know for sure is a proper scan — we won't know from the light alone, and neither should you rely on guesswork.
What's the difference between a flashing and a steady check engine light?
A steady light means you should get it checked soon. A flashing light is more urgent — it can indicate a fault serious enough to cause engine or emissions system damage, so it's best to stop driving and get it looked at as soon as possible.
Can you diagnose a car without a scan tool?
Older vehicles without an onboard computer need manual diagnostic checks and physical inspection rather than a plug-in scan. We're equipped for both older and newer vehicles.
How long does a car diagnostic take?
Many faults can be diagnosed the same day. Intermittent issues sometimes take longer, since we may need to monitor live sensor data while the engine runs to catch the fault as it happens.
