OBD stands for On Board Diagnostics. It is the system built into modern vehicles that monitors engine performance, emissions, and electrical systems. When something goes wrong, your car’s OBD system will often trigger a check engine light.
With professional scan tools, we can connect to your vehicle’s OBD system to quickly find fault codes, diagnose problems, and carry out the right repairs. This saves you time, money, and guesswork.
At OBD On Board Diagnostics, we specialise in making sense of these fault codes — turning that warning light on your dash into clear answers and effective solutions.
We partner with AltTune and Alientech to bring you advanced ECU solutions tuned for New Zealand conditions. All files are dyno-tested, safe, and customised for your vehicle.
