Get to the Root of the Problem
Modern vehicles are full of sensors, control modules and electronics, and that complexity is exactly what makes a proper diagnostic scan so valuable. Guessing at a fault often means throwing parts at the problem. A thorough scan tells you what's actually wrong, the first time. S & A Automotive offers car diagnostics and fault finding in Cairns, with equipment covering the major makes serviced in Australia. Our mechanics carry out ECU fault code reading, live data analysis, electrical troubleshooting and sensor replacement to resolve check-engine lights, intermittent faults and electrical gremlins.

What a Diagnostic Visit Covers
Using state-of-the-art diagnostic equipment, our mechanics get to the root of the problem quickly, covering everything from a simple fault code scan through to in-depth electrical troubleshooting. A typical diagnostic visit includes:
- ECU Fault Code Scan — Reading and interpreting stored and live fault codes across engine, transmission, ABS and body control modules.
- Live Data Analysis — Watching sensor inputs in real time while the vehicle runs to confirm a fault before any parts are replaced.
- Electrical Troubleshooting — Tracing wiring faults, checking connector integrity and identifying parasitic battery drains.
- Sensor and Component Replacement — Once a fault is confirmed, we replace the failed component and clear codes to verify the repair holds.
Frequently Asked Questions
It means the engine control unit has logged a fault code from one of the vehicle's sensors or systems. The cause can range from something minor like a loose fuel cap through to misfires, emissions faults or a failing sensor. A diagnostic scan reads the stored code and live data to identify the underlying issue rather than just clearing the light.
