ENGINEDIAGNOSTICSSutherland Shire
Advanced computerised diagnostics to pinpoint engine faults fast. We scan, interpret and fix — saving you time, money and the guesswork. All makes and models welcome. SSAC carries Genuine dealer level scan tools for scanning, software updates and programming vehicles.
What We Diagnose
From a glowing check engine light to mysterious symptoms — our advanced engine diagnostics uncover the root cause the first time.
Check Engine Light Diagnosis
Your check engine light is on and you don't know why. We plug in, read the fault codes and give you a clear, honest explanation of what's going on.
OBD-II Full System Scan
A complete scan of all vehicle electronic control units — engine, transmission, ABS, airbags, TPMS and more — to identify stored and pending fault codes.
Live Data & Sensor Analysis
We go beyond fault codes — reading live sensor data streams from oxygen sensors, MAF, coolant temp, fuel trims and more to uncover hidden engine issues.
Fuel System Diagnostics
Diagnosing rough idle, poor fuel economy or misfires? We test injectors, fuel pressure, rail pressure and fuel trim data to isolate the problem accurately.
Battery & Charging System Test
Slow starts, dimming lights or a mystery drain? We test the battery, alternator output and charging system to find the fault before it leaves you stranded.
Cooling & Overheating Diagnosis
Overheating warning, coolant loss or a temperature that climbs too fast? We diagnose thermostats, water pumps, head gaskets and cooling fans with precision.
Warning light on? Don't ignore it.
Book a diagnostic scan and find out exactly what's going on before a minor fault turns into a costly repair.
Genuine Scan Tools for Every Make
We invest in genuine, manufacturer-level diagnostic tools — not cheap generic code readers. That means we get the same deep system access as a dealership for a huge range of makes and models, covering engine, transmission, ABS, airbags, TPMS and every module in between.
Makes we have genuine scan tools for:
