ISO 14229-2 (UDS Session Layer services)
UDS allows diagnostic testers (client nodes) to control diagnostic functions in Electronic Control Units (ECUs or server nodes). These functions include reading and clearing Diagnostic Trouble Codes (DTCs), reading real-time sensor data, controlling input/output signals, and flashing new software into the ECU memory.
