2.5.2.11. Local network of the controler (CAN)

The PCM block transfers/receives information from CAN.
The local network of the controler (CAN) hands over the following information:
– prohibition of reduction of a torque;
– frequency of rotation of the engine;
– speed of a vehicle;
– provision of a butterfly valve;
– temperature of cooling liquid;
– passable way;
– injection of fuel (quantity);
– MIL condition;
– condition of a lamp of the alarm system of the generator;
– working volume of cylinders of the engine;
– number of cylinders;
– type of system of an admission;
– type and supply of fuel;
– country;
– type of a box of transfers/axis;
– circle of a wheel (forward / back);
– desirable position of the lever of gear shifting;
– HOLD switch condition.
The local network of the controler (CAN) receives the following information:
– speed of a wheel from anti-blocking system of brakes;
– the forward left;
– the forward right;
– the back left;
– the back right;
– the passable way from anti-blocking system of brakes;
– a condition of brake system from anti-blocking system of brakes;
– request for torque reduction from anti-blocking system of brakes;
