The PCM block transfers/obtains information from CAN.

The local network of the controller (CAN) transfers the following information:

– prohibition of reduction of torque;

– frequency of rotation of the engine;

– vehicle speed;

– provision of a butterfly valve;

– temperature of cooling liquid;

– the passable way;

– injection of fuel (quantity);

– condition of MIL;

– condition of a lamp of the alarm system of the generator;

– effective engine cylinder capacity;

– number of cylinders;

– type of system of an admission;

– type and supply of fuel;

– country;

– transfers/axis box type;

– circle of a wheel (forward / back);

– desirable position of the lever of gear shifting;

– condition of the HOLD switch.

The local network of the controller (CAN) obtains the following information:

– wheel speed from anti-blocking system of brakes;

– forward left;

– forward right;

– back left;

– back right;

– the passable way from anti-blocking system of brakes;

– a condition of the brake system from anti-blocking system of brakes;

– request for reduction of torque from anti-blocking system of brakes;
