The protocol is used to diagnose errors and reprogram ECUs. Unified Diagnostic Service (UDS) according to the ISO 14229 standard is a protocol used by diagnostic systems to communicate with ECUs in vehicles. The device requesting the information is called the Modbus Master and the devices supplying information are Modbus Slaves. It is a method used for transmitting information over serial lines between electronic devices. Modbus is a communication protocol developed by Modicon systems. There is no need to establish connection prior to data transfer. Unlike TCP, it is unreliable and connectionless protocol. UDP is a part of Internet Protocol suite, referred as UDP/IP suite. User Datagram Protocol (UDP) is a Transport Layer protocol.
TCP/IP, or the Transmission Control Protocol/Internet Protocol, is a suite of communication protocols used to interconnect network devices on the internet. Originating in the car and heavy-duty truck industry in the United States, it is now widely used in other parts of the world. The Society of Automotive Engineers standard SAE J1939 is the vehicle bus recommended practice used for communication and diagnostics among vehicle components.
