OBD Simulator Overview

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 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 select the active protocol, monitor OBD traffic, and upload firmware updates.

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 has not been unlocked will produce a "PROTOCOL LOCKED" message.

Features

• Support for all legislated OBD-II protocols:
  • SAE J1850 PWM
  • SAE J1850 VPW
  • ISO 9141-2
  • ISO 14230-4 (KWP2000)
  • ISO 15765-4 (CAN 250/500 kbps, 11/29 bit)
• Functional and physical addressing
• Each PIM supports three 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 PIM configuration and OBD traffic monitoring
• On-the-fly OBD protocol switching
• Standard J1962F connector
• Firmware upgradeable

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)
