Diagnostic Dealer Tools

Cartronics use official factory dealer diagnostic tools and have full access to specialised wiring diagrams and workshop manuals for all vehicles.

We utilise a vast range of the latest tools, scanners and car diagnostic systems to assist our Engineers in locating and fixing the vehicle and never use Chinese copy-cat programs or fake software from the internet as these can seriously damage the vehicle.

Most cars manufactured in the last 15 years have complex ECU (Electronic Control Units) that require software and firmware updates in order to improve and even fix known issues. In turn, this may have a knock-on effect on the car’s other electronic components.

Cartronics can update and code ECU’s on all major car makes. This may be required if a used or even new part is installed or in the event of a fault.  

Diagnostic Questions

What is car diagnostics?

Car diagnostics is the skill of finding, and rectifying, faults within a vehicle’s computer system (ECU). These faults can produce error codes that can only be read by specialist diagnostic equipment and fixed by our auto electrical engineers.

Can you tell me the exact problem with my vehicle?

Yes! Our diagnostic service ensures we pinpoint the problem with your vehicle, first time. We do not guess or replace random parts simply hoping for the best. This saves our customers’ time and money by avoiding redundant repairs and replacements.

Do you offer services for mechanical garages and car sale professionals?

Yes. Cartronics have a long history with diagnosing and repairing vehicles for mechanics, garages and car sale garages. We welcome any challenge so if you are a professional who wants to avoid redundant repairs and excessive dealership prices, get in touch.
