Streamlining End-of-Line ECU Testing with UDS over CAN

Rutika Pawar

Abstract: Modern vehicles have electronic control devices called Electronic Control Units (ECUs). These ECUs use a communication system called the Controller Area Network (CAN) to share information. CAN is reliable, strong, and helps prevent errors. However, as the number of ECUs in a vehicle increases, identifying issues in a specific ECU becomes more challenging. To diagnose these electronic devices and circuits, a standard communication method called Unified Diagnostic Services (UDS) is used. This enables to diagnose the ECU and troubleshoot it without taking it out from the vehicle assembly. This paper explains how UDS is used to test inputs and outputs in a vehicle.
