The following functions are separately controlled:
- lambda adjustment, knock adjustment and idle stabilization;
- control of electrical circuits and signals from sensors;
- control of electrical circuits of injectors, solenoid valves, fuel pump relay, ignition module, ignition coil and throttle control.
If diagnostics detects a defect, it leaves it in memory until:
- the defect will not be corrected and information about it will be erased;
- the defect will not be identified as sporadic, and if after a certain number of engine starts it does not occur again; then it is automatically erased.
If the diagnosis determines a sensor defect, the values of the time program are entered and thus the vehicle's operability is maintained. Only the signal from the speed sensor is not simulated and in its absence it is impossible to start the engine.
