Operating Instructions

Vehicle Compatibility

The ELM327 USB adapter is broadly compatible with various vehicle makes and models. It is specifically designed for use with:

• Ford: F150, F250, Cars & F-series Trucks (12V)
• Lincoln
• Mazda (after 1996, excluding new 2019+ Mazda 3 and CX-30)

HS-CAN and MS-CAN Switch

The adapter features a physical toggle switch to select between High-Speed CAN (HS-CAN) and Medium-Speed CAN (MS-CAN) protocols. This switch is crucial for accessing different modules within your vehicle's network.

• HS-CAN: Typically used for powertrain control modules (PCM), transmission control modules (TCM), and other critical systems.
• MS-CAN: Used for body control modules (BCM), infotainment systems, and other comfort/convenience features.

Refer to your specific vehicle's wiring diagrams or FORScan documentation to determine which CAN bus is required for the module you wish to access or modify. The switch position determines which network the adapter communicates with.

Troubleshooting

If you encounter issues while using the ELM327 USB adapter, consider the following troubleshooting steps:

• Connection Issues:
  • Ensure the CH340T USB driver is correctly installed. Verify installation in your computer's Device Manager.
  • Confirm the adapter is securely plugged into both the vehicle's OBD2 port and the computer's USB port.
  • Ensure the vehicle's ignition is in the "ON" position.
  • Try a different USB port on your computer.
  • Restart your computer and the FORScan software.
• Software Not Recognizing Adapter:
  • Verify that you are using a supported Windows operating system (XP, Vista, 7, 8, 10). This adapter is not compatible with macOS or Chrome OS.
  • Check FORScan settings to ensure the correct COM port is selected for the adapter.
  • Ensure you have the latest version of the FORScan software.
• Limited Functionality / Module Access:
  • Confirm the MS-CAN/HS-CAN switch is in the correct position for the module you are trying to access. The switch is not labeled, so you may need to try both positions.
  • Some advanced programming features in FORScan may require an extended license. Ensure your FORScan license supports the desired function.
  • Newer vehicle models (e.g., 2019+ Mazda 3 and CX-30) may not be fully supported by this adapter.
• "Reader not recommended" Message:
  • While the adapter is generally compatible, some specific vehicle models or FORScan versions might display this message. It may still read basic PCM data but might not access all modules.
