So, what happens with that warning light when you take your car to a garage? The car diagnostic check and your on-board diagnosisДЄ car diagnostic test will deliver details from your carвЂ™s many sensors to alert your technician to which component isnвЂ™t working correctly. Once repaired, the mechanic can also clear any fault codes and warning lights. Trained technicians and mechanics can then access the fault codes to determine the component that isnвЂ™t operating correctly.

When a sensor delivers a fault, the code is stored in your carвЂ™s computer system. Your ECU monitors your major engine functions, electrical components, and measures your vehicle emissions. Your ECU is where each of your engineвЂ™s sensors reports anything amiss, and if thereвЂ™s a problem, it will illuminate an appropriate warning light on your dashboard. This is your carвЂ™s brain-an on-board computer known as the Engine Control Unit. Your ECU and the car engine diagnostic testД®very car rolling off a production line today will have an ECU.

At Kwik Fit, we can read your check engine light fault codes using our Bosch OBD II diagnostic equipment to provide a full explanation of the issue. In order to diagnose a check engine light fault, an OBD2 scanner must be used to find out where the issue lies. It could be something quite trivial like a loose fuel cap but it could be something much more serious like a faulty catalytic converter. If your check engine light is on itвЂ™s important that a technician inspects your vehicle as soon as possible before further, more serious damage is caused to your car engine, especially if your check engine light is flashing as this usually indicates a serious problem or emergency.ДЄs the most complex part of any vehicle, an engine fault could be caused by any number of factors.

While a warning light may display on the dashboard alerting you to an issue, a diagnostics fault code check is required to start to understand the issue and determine if a more in-depth diagnostic session with a specialist technician is required.

There are literally hundreds of potential OBD2 error codes that can only be read by specialist on-board diagnostic fault code readers. These codes can be meaningless without the proper diagnostic code reader so we use an OBD scanner to read the codes and find out more specific information about the nature of the problem. The relevant dashboard warning lights will then be displayed. When an issue is identified the ECU generates an error code. Sensors all around the vehicle report back to the ECU if there are problems such as low fluid levels or increased engine temperature. Most modern vehicles today contain a network of on-board computers known as Electronic Control Units (ECUs) which continually monitor the performance of the vehicle and can self-diagnose faults. When a car warning light illuminates on your dashboard or an error message or code appears, a car diagnostics check or fault code check can help identify the problem before more serious damage occurs.
