To handle the size and right order of both the data blocks being sent/received and the memory blocks where such data blocks should be stored.To handle the start and stop of data transfer.

To set the server into a reprogramming session mode.The main job of UDS in such operation would be: The combination of both again creates a new standard called UDSonCan protocol. So this diagnostic protocol is now implemented in most of the vehicles over the different communication protocols. But due to certain limitations, they have developed a new standard ISO14229 called UDS protocol. Before the UDS protocol, the automotive industry was supposed to use the KWP-2000 protocol. The application of UDS in ECU flash programming is a mainframe in the automotive vehicle system. The CAN and UDS protocol are among them making the automotive vehicles smart for any kind of vehicle service work. This combination standard makes another standard protocol to which you need to use any kind of vehicle work from flashing to diagnostic. It is nothing like that you will flash the ECU only by using a communication protocol, you need to use any diagnostic protocol for ECU flashing. To communicate any external diagnostic tool for ECU flashing, you need to use it. In current edge technology, there are different types of communication protocols. There are different methods available to flash the ECU in any automotive vehicle. The purpose of this module is to show the process and items that could be used in terms of data transfer between a client and a server, as suggested by UDS.В One of the uses of UDS is the ECU flashing, typically to load a new version of an application program with fix or enhancements.
