ECUsim 2000/5100 1.0 Introduction ECUsim 2000 and 5100 are software-configurable, stand-alone benchtop OBD simulators. Internally, the objects (ECUs, DTCs, PIDs, and Freeze Frames) are created dynamically at runtime, and stored in RAM. Consequently, objects can be created and deleted at will, but are lost after a software reset, or when power is removed.

Programming Manual 2.2 General ECUsim Commands SF on|off Turn “Fault” mode on or off. Fault mode is off by default. Protocol # SOMM on|off Turn OBD bus monitoring on or off. OBD monitoring is on by default. SOMMT on|off Turn timestamp printing on or off. Timestamps are on by default. SOMT header, data Transmit OBD message. The message will be sent over the active protocol set by the SP command.
ECUsim 2000/5100 2.4 ECU Commands E ecu_id, on|off Enable/disable specified ECU. This allows the user to quickly remove an ECU from OBD communication, without affecting the ECU’s properties. User still has the ability to change the attributes of disabled ECUs (set VIN, add DTCs and PIDs, etc). EA ecu_id Add an ECU. This command creates a blank ECU.
Programming Manual FTD ecu_id, fault_set, frame_num Delete the DTC in the specified freeze frame. FPD ecu_id, fault_set, frame_num, pid_num Delete the specified PID FT ecu_id, fault_set, frame_num, dtc Set a specified frame’s DTC. This command is used to change an existing DTC (created by the FDA command). FPSD ecu_id, fault_set, frame_num, pid_num, pid_data Set the PID data for the specified freeze frame.
ECUsim 2000/5100 3.0 Event Messages Status message, indicates that a Fault Event was generated via the ‘Fault’ button press, or a software command. ECUsim is waiting for the OBD tester to start the 5baud ISO 9141 or ISO 14230 initialization sequence. ECUsim is waiting for the OBD tester to start the fast ISO 14230 initialization sequence. <5 BAUD INIT: OK> Detected a successful 5 baud initialization sequence.
Programming Manual 5.0 Examples 5.1 Creating a Basic ECU In this example, we will create a basic custom ECU. This ECU will use the J1850 PWM protocol and support one PID (RPM). Notes: After any reset, the simulator automatically creates default ECUs. Therefore, the first step is to delete the default ECUs. The knobs are assigned to the first three ECUs (IDs $0, $1, and $2). We want to set the RPM to a fixed value, therefore we will use the next available ID ($3).
ECUsim 2000/5100 >0100 request supported PIDs in the $01-$20 range 41 6B 10 41 00 00 18 00 01 95 >0120 request supported PIDs in the $21-$40 range 41 6B 10 41 20 00 02 00 00 5E Notice that the PAUS command encoded the existing PID ($0C), as well as the new PIDs. 5.3 Adding DTCs ECUs can have stored, pending, and permanent DTCs. A given DTC can be added to either a “no fault” or “fault” fault set. A “fault” event is generated when the user presses the “FAULT” button, or enters the SF on command.
