4 ECUsim™ 2000 User Guide
1.0 Overview
ECUsim 2000 is a small, lightweight, entry level benchtop simulator that can
be used for testing and development of OBD hardware and software. It
supports all legislated OBD protocols, fixed and user adjustable parameter IDs
(PIDs), diagnostic trouble codes (DTCs), freeze frames, VIN, 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.
ECUsim 2000 features a USB connection which can be used to configure the
simulator and to monitor OBD traffic.
The simulator can be purchased with any combination of “unlocked” OBD
protocols, from as few as one to as many as five. Attempting to switch to a
protocol that is locked will produce a “PROTOCOL LOCKED” message.
