SK Pang electronics TEENSY4.0-OBDII-SIM-EN CAN Bus ECU Simulator include

Teensy

Product Information

Specifications:

Product Name : Teensy 4.0 OBDII CAN-Bus ECU Simulator with Enclosure
Model Number: TEENSY4.0-OBDII-SIM-EN
Manufacturer: SK Pang Electronics Ltd

Product Usage Instructions

Power Supply
The simulator is supplied with a 12v PSU with plugs for US, UK, EU, AU. Swap out the plug to suit your country. Plug the PSU into the mains and switch it on. Connect the cable to the +12v DC input of the simulator.

CAN Terminator
Ensure the CAN terminator switch is set to 1 (enabled).

Connection Setup
Connect your OBDII device to the OBDII port. Start your application to read the OBDII parameters.

Parameter Adjustment
Use the Parameter adjustment potentiometers to adjust the parameter value. The ACT indicator should flash when a request is being made.

MIL and DTC
Press the DTC switch to set the MIL indicator on. The MIL indicator can be cleared by sending a clear message in your application.

User Button
The SW1 switch can be used for your own function.

Firmware Modification:
You can modify the firmware to suit your own needs by following these steps:

Install Arduino IDE from: Arduino Software
Add Teensyduino add-on from: Teensyduino Add-On
Access Teensy sketch from: Teensy Sketch Repository
Refer to a list of OBDII PIDs from: OBDII PIDs List

Frequently Asked Questions (FAQ)

Can I use this simulator without connecting it to an OBDII device?
While the simulator is designed for testing OBDII interfaces, you can still adjust parameters using the potentiometers and observe the indicators without connecting to an OBDII device.
How do I know if the simulator is receiving power?
Check if the ACT indicator flashes when you adjust parameter values using the potentiometers. This indicates that the simulator is receiving power.

Overview

Usage

Power supply

The simulator is supplied with a 12v PSU with plug for US, UK, EU, AU. Swap out plug to suit your country.
Plug the PSU into the mains and switch on. Connect the cable to the +12v DC input (6) of the simulator.

CAN Terminator
Ensure the CAN terminator switch (8) is set to 1 (enabled).

Connect Up
Connect your OBDII device to the OBDII port (7). Start your application to read the OBDII parameters.

Parameter Adjust
Use the Parameter adjustment potentiometers (1) to adjust the parameter value. You should see the ACT indicator (2) flashes when a request is being made.

MIL and DTC
Press the DTC switch (5) this will set the MIL indictor on (3). The MIL indicator can be cleared by sending a clear message in your application.

User Button
SW1 switch (4) can be used for your own function.
