However, the applicable services are left to the manufacturer and not defined by the standard. OBD accessories for Citroen. UDS as a diagnostic protocol was developed to unify all the diagnostics standards that existed previously and to come up with a single valid set of diagnostic services for the automotive ECUs. To cater to this need of the hour, various vehicle diagnostic protocols were conceptualized and developed.


Please only after arrangement! If the TesterPresent service is missing for a certain period of time, the diagnostic session is terminated, and the ECU returns to normal operation mode.

The average data rate of KWP is between 1. OBD accessories for Opel. Moreover, in a periodic communication sequence based on UDS standard, the test equipment sends periodic requests for updated information from automotive ECUs. Softing experience Softing played an active role in standardization from the very beginning, contributing its extensive communication expertise.
