As soon as Geberit showed that there was no bus, all the fault lights went on.

The reason why the automobile fault lights are all on is that the vehicle starts self-checking, which is a normal phenomenon. If the vehicle instrument light is still on after the vehicle is started, it may be caused by the fault of the instrument panel line, the fault of the ECU CAN bus and the poor contact of the ECU CAN interface. The reason why the car fault light is on is that the car has broken down, reminding the owner that the car needs overhaul. Automobile fault light indicates many reasons, such as engine fault, gearbox fault, brake system fault, water temperature fault and so on. It is necessary to check and confirm the car fault according to the display on the dashboard of the car.

The following are the reasons why the engine fault light comes on:

1, the exhaust emission is not up to standard, such as poor fuel, failure of three-way catalyst, excessive carbon deposition in intake pipe, blocked fuel nozzle, failure of oxygen sensor, occasional misfire of engine, etc. , engine fault lights will be on, and poor oil quality will lead to the most engine fault lights;

2. The fault light is on due to poor engine system, such as the fault of accelerator pedal sensor, throttle position sensor, air flow meter and crankshaft position sensor. Or poor line contact, etc. , it will cause the engine fault light to light up;

3. Some vehicle gearbox system failures are also indicated by engine failure lights, such as internal gearbox failures, slippage, high temperature, etc.
