ECUsim 2000 OBD Simulator

ECUsim™ 2000 is a small, lightweight, entry level OBD simulator that is an indispensable tool for OBD hardware and software development and testing.It supports all legislated OBD-II 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 with the device under test is made through a standard SAE J1962 female connector.

ECUsim 2000 features a USB connection which can be used with the ECUsim Commander software to create custom ECUs or modify existing ECUs.

The simulator can be purchased with any combination of "unlocked" OBD-II protocols, from as few as one to as many as five. Attempting to switch to a protocol that has not been unlocked will produce a "PROTOCOL LOCKED" message.

The 2000 is available in 3 editions (Standard, Professional, and Ultimate) which offer varying levels of user control. The Professional & Ultimate editions feature over 40 software commands that provide complete administration of the simulator using ECUsim Commander, and allow you to create custom ECUs, add/delete DTCs and freeze frames, create PIDs, and dynamically assign their values.

Key Features

• Functional and physical addressing
• Each PIM supports 3 virtual ECUs: ECM, TCM, and ABS
• Five knobs assigned to frequently used PIDs:
  • Coolant Temperature
  • Engine Speed (RPM)
  • Vehicle Speed
  • Oxygen Sensor Voltage
  • Mass Airflow (MAF)
• Supported SAE J1979 modes: 1, 2, 3, 4, 7, 9, and A.
• "MIL", "Link" and "Power" indicators
• "FAULT" button
• USB connection for configuration, control, and bus monitoring
• On-the-fly OBD protocol switching
• Standard J1962F connector
• Firmware upgradeable
• Custom ECUs*
• Custom PIDs*
• Custom DTCs*
• Custom freeze frames*
• User settable VIN & CAL ID
• Send OBD messages under software control
• Knobs assignable to PIDs**
• Signal generator (sine, triangle, square, random)**

Typical Standalone Configuration

In the above example, ECUsim 2000 simulates a vehicle's ECU. OBDLink SX is the chosen interface between ECUsim 2000 and a laptop running OBD-II software.

User Interface Diagram

1. Power LED
2. Link LED
   The function of this LED depends on the protocol in use:
   a. ISO 9141-2 and ISO 14230-4 protocols: the LED is on while at least one ECU is initialized. The LED dims when an OBD message is received.
   b. J1850 and CAN protocols: the LED blinks when an OBD message is received.
3. Malfunction Indicator Light
4. Knobs assigned to the five commonly used Mode 1 PIDs.
5. Fault button
   When pressed, the following happens:
   a. Set MIL and number of stored DTCs (Mode 1, PID 01)
   b. Generate pending, stored, and permanent* DTCs
   c. Generate freeze frame data
6. Configuration DIP switch has two switches that set protocol attributes for ISO 15765-4 (CAN). Switch number 1 is also used to select the init type for ISO 14230-4:
   a. 29 bit/11 bit. Selects CAN frame ID type.
   b. 500 kbps/250 kbps. Selects CAN baud rate.
   c. Fast Init/5 Baud Init. Selects the type of initialization for ISO 14230-4.
7. Diagnostic Link Connector (DLC)
8. USB connector
9. Power jack (12 VDC)

* SAE J1979 defines permanent DTCs only for ISO 15765-4 (CAN)

• Support for all legislated OBD-II protocols:
  • SAE J1850 PWM (Ford)
  • SAE J1850 VPW (GM)
  • ISO 9141-2 (Asian, European, Chrysler)
  • ISO 14230-4 (Keyword Protocol 2000)
  • ISO 15765-4 (CAN 250/500 kbps, 11/29 bit)
