- 55-channel injection system control unit;
- static ignition system;
- injection blocking relay, used only for supplying the engine overheating protection relay;
- control of the electrical supply circuit of the fuel pump;
- using G01 and G02 modes to switch between "condition monitoring" and "fault monitoring";
- using control modes to select actuators (only when the ignition is on);
- visualization of the cyclic opening mode of the electromagnetic valve for cleaning the absorber;
- reading by XR25 device (#...) of the actual value in case of a malfunction of a component of the injection system (the function does not work in the backup mode of the injection system control unit);
- programming zones for special parameters of adaptive correction of fuel mixture composition;
- availability of an algorithm in backup mode due to failure of the absolute pressure sensor (calculation of the pressure value based on information about the throttle position and engine crankshaft speed);
- injection interruption at the maximum permissible engine crankshaft speed of 6200 min⁻¹.
When the ignition is turned on, the indicator lamp located in the instrument cluster flashes (the period during which the injection system control unit identifies the anti-theft system code), then lights up continuously for 3 seconds and then goes out. Simultaneous lighting of the fuel injection system warning lights and the need for service indicate a malfunction
Malfunctions that cause the warning light to come on:

- absolute pressure sensor;
- throttle potentiometer;
- fuel injectors;
- idle speed control valve;
- lack of information about the speed of a moving vehicle.
