Do you have a warning light on your dashboard? This will have been triggered by your car engineโs Electronic Control Unit (ECU). Modern cars generally have several ECUs to manage the multitude of electronic systems including Engine, Braking, Lighting, Traction Control and Airbag systems. These ECUs are connected to a network of sensors which monitor the vital signs of all these systems. If an ECU detects an incorrect reading from one or more of its sensors, it will trigger the relevant warning light on your dashboard and store any fault codes in its memory.
By connecting our state-of-the-art car engine diagnostics tools to your carโs ECUs we can download the error messages stored. These messages are usually in the form of a sequence of numbers. Our diagnostics tools can match these numbers (error codes) to their meaning, and armed with this information we can start trying to rectify the problem which initially triggered the System Warning Light.
