ECUsim 5100 OBD Simulator

ECUsim™ 5100 is a small, lightweight, benchtop simulator that can be used for testing and development of OBD devices and software. It supports all legislated OBD protocols, fixed and user adjustable parameter IDs (PIDs), diagnostic trouble codes (DTCs), freeze frames, and many other SAE J1979 services.

The unit has five knobs assigned to common PIDs, a "fault event" button, and indicator lights for power, connection, and MIL (Malfunction Indicator Light). Physical connection to the scan tool is made through a standard SAE J1962 female connector.

The simulator can accept from one to three plug in modules (PIMs), each configured for a different OBD protocol. The user is able to select any one of the three protocols using a three position switch, or make them active at the same time.

ECUsim 5100 features a USB connection which can be used to configure the PIMs and to monitor OBD traffic.
