How to perform the onboard computer test of the Renault Megane II

Model: Renault Megane Megane 2 - Years 2002-2010
Part: Onboard computer

Let's see how to perform a test on the onboard computer of the Renault Megane II: insert the card into its slot and press the start button, while also pressing the menu button, for five seconds. This way, the onboard computer enters test mode, and we can see the needles and lights performing an automatic calibration. By pressing the button located at the end of the lever on the right side of the steering wheel, we can see the firmware version; pressing again tells us how many liters of gasoline are in the tank; with a subsequent press, we get information on how many liters/hour are passing through the injectors at that moment; with the next press, we will see the overall test result.
