The malfunction indicator lamp warns the driver that something is wrong with the engine management system (Trionic/Motronic).
The control module feeds out battery positive voltage on pin 12 which is grounded by the engine management system when a fault is registered and the
lamp lights.
If the car is equipped with Motronic, the malfunction indicator lamp lights when the ignition is switched on and does not go out until the engine has
started provided there are no faults that keep the lamp lit. If the car is equipped with Trionic, the lamp lights during the normal lamp check when the
ignition is switched on and then goes out after 4 seconds, except when the engine is running and there is a fault.
