2.5.2.11. Local network of the controller (CAN)

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;

The electrical circuitry of a control system of the Mazda 3 car with the L8, LF engine (the general area) and L3: 1 – electric motor of the fan of the cooling system No. 1; 2 – electric motor of the fan of the cooling system No. 2; 3 – relay of the fan of the cooling system No. 1; 4 – relay of the fan of the cooling system No. 2; 5 – relay of the fan of the cooling system No. 3; 6 – relay of the fan of the cooling system No. 4; 7 – PCM block; 8 – L3 engines; 9 – LF and L8 engines (hot area)


– a configuration of the brake system from anti-blocking system of brakes.

Fig. 2.231. The electrical circuitry of a control system of the Mazda 3 car with the L8, LF engine (the general area): 1 – electric motor of the fan of the cooling system No. 1; 2 – electric motor of the fan of the cooling system No. 2; 3 – relay of the fan of the cooling system No. 1; 4 – relay of the fan of the cooling system No. 2; 5 – PCM block; 6 – with the air conditioning system
