Controller Area Network (CAN)
PCM unit transmits / receives the information from the CAN. Controller Area Network (CAN) reports the following information: - Prohibition of torque reduction; - Engine speed; - The speed of the vehicle; - Throttle position; - The temperature of the coolant; - distance traveled; - Fuel injection (amount); - The state of MIL; - The state of the generator warning lights; - Engine displacement; - Number of cylinders; - Type intake system; - Type and fuel supply; - a country; - Type of gearbox / axle; - Circumference of the wheel (front / rear); - The desired position of the shift lever; - Switch status HOLD. Controller Area Network (CAN) received the following information: - The speed of the wheel anti-lock brakes; - The front left; - The front right; - Rear left; - Rear right; - The distance traveled by the anti-lock braking system; - The state of the brake system of the anti-lock braking system; - A request to reduce the torque of the anti-lock braking system;
