Car Diagnostics - Gosport

Modern vehicles are complex systems, and when something goes wrong, a warning light on the dashboard is often the first sign. Diagnostics is the process of reading and interpreting the fault codes stored by your vehicle’s electronic control units, giving a clear starting point for identifying what’s wrong and what needs to be done.

At RCJ Automotive, we use Premier Diagnostics equipment, giving us the capability to work across a wide range of makes and models with accuracy.

What Diagnostics Can Identify

Engine management faults
ABS and traction control issues
Airbag and SRS system faults
Transmission and gearbox fault codes
Sensor faults across multiple vehicle systems

When Should You Book a Diagnostic Check?

Any warning light appears on the dashboard
Your vehicle is failing or likely to fail an emissions test
You notice a change in performance, fuel economy, or behaviour
Pre-purchase inspection of a used vehicle

Diagnostics Isn’t Just Reading Codes

Pulling a fault code is only part of the process. Interpreting what it means in the context of your specific vehicle, and knowing what further checks are needed to confirm the root cause, is where experience matters. At RCJ Automotive, our technicians use diagnostic data as a starting point, not an end point, ensuring the right repair is carried out rather than parts being replaced unnecessarily.

If a warning light is showing on your dashboard, contact RCJ Automotive in Gosport and we’ll get to the bottom of it.
