car diagnostic in Portsmouth

What is a diagnostic inspection?

Modern cars have an onboard computer or Engine Control Unit (ECU). This continually assesses performance, with sensors throughout the car letting the ECU know of issues such as raised engine temperature, low fluid levels or problems with emission levels or the windscreen wipers. The ECU triggers an error once a problem has been found, and the relevant dashboard warning light will flash, but there are hundreds of potential error codes, which only specialist diagnostic equipment can read. So when a warning light flashes on the dashboard, a diagnostics check is needed to assess how bad the problem is, and what may have caused it.

We use state of the art diagnostic equipment

Live data shows multiple readings from across the engine to assess whether everything is working as it should. The equipment can also check and rectify braking systems where there’s an electronic handbrake, and adjust headlights where possible. You don’t need to go to a dealership to get diagnostic testing done. Most garages and workshops will carry out diagnostic testing for nearly all models and types of vehicle.

What happens when my dashboard illuminates a warning light?

The warning light is just the beginning—it doesn’t give the whole picture. There are hundreds of parts in your engine, so the exact nature of the fault may not be immediately apparent.

Examining fault codes to identify the problem

A diagnostic check accurately identifies the fault, avoiding more serious problems that could lead to costly repairs, potential safety hazards or worse damage. With these tests, your car is plugged into sophisticated diagnostic equipment which reads the error codes your car’s ECU has generated to explain the issue in full. Diagnostic checking looks for errors across various vehicle systems, including tyres, engine management, lights, emissions and more.
