Diagnostics

That check engine light rarely tells the full story on its own. Modern vehicles run on dozens of interconnected electronic systems and pinpointing exactly what’s wrong takes more than guesswork. At Cornubia Auto Care, we use up-to-date diagnostic equipment to read what your vehicle’s systems are actually telling us – and find the real cause, not just the symptom. 

Poor performance, strange noises, electrical glitches, or a dashboard warning light – our technicians work through each one methodically, diagnosing the fault and recommending the repair that actually fixes it. That accuracy is what saves you from paying for parts or repairs you didn’t need. 

Our diagnostic services identify problems quickly and accurately

Every vehicle we test – passenger cars, 4WDs, or light commercials – goes through the same precise process. We connect state-of-the-art scanning equipment to assess each system individually, cross-checking results, so faults are pinpointed rather than assumed.

Catching a fault early is often the difference between a minor fix and a major repair bill – our thorough process is built to surface those hidden issues before they escalate.

Getting clear answers, not just fault codes

A warning light or performance issue can point to several different underlying causes, which is why our technicians don’t stop reading the fault code – they inspect the related components and run further testing to confirm exactly what’s going on. 

Engine management faults, failing sensors, electrical faults, drivability concerns – whatever the source, we explain it in plain terms and outline the repair options available. Once you’ve got the full picture, we’ll carry out the right fix to get your vehicle back to reliable, dependable performance.
