ECU diagnostics validator using CANUSB

An ECU diagnostics provides information about ECU behavior which in turn provides the overall health of the vehicle. An OBD (On-Board Diagnostics) takes necessary corrective actions for preventing accidents and hazards by detecting vehicle system's malfunction. The driver and passenger safety can be taken care with the help of diagnostics. For ECU diagnostics validation, most of the OEMs, Tier-1, and Tier-2 use a Vector Tool “CANoe” during ECU development phase. The CANoe is very powerful tool. However, its cost is ~ €10,000. The proposed system can be used to perform the similar functionality of ECU diagnostics validation during ECU development phase. It uses CANUSB as hardware interface and software developed in Microsoft C# language as application software. It is the cost-effective special tool which uses single CAN channel for transmitting and receiving various CAN messages to/from ECU. Using this tool, the diagnostic messages and vehicle messages can be simulated & sent and ECU response can be validated. The tool would be having user-friendly easy to use GUI, manual as well as cyclic auto transmission mode with message logging feature. The overall tool cost would be ~ 35,000.
