Designed to connect securely and easily to a CAN network, a device is designed to listen as well as read the whole network information without having to disconnect from the network wires. Because the wires are inserted into CANDO, no longer needs to lay the vehicle’s power cords. The CANDO interface is a small, efficient, easy-to-install hardware used to obtain and read CAN network information. The device receives vehicle signals easily without the need to connect directly to the car’s CAN.
