Important Compatibility Note

Not every Toyota, Lexus or Scion ECU is supported. OBD read capability is not universal. Before ordering, confirm the ECU manufacturer, ECU part number, processor/MCU and required connection method. Newer vehicles may use unsupported ECU generations.

OBD Power Safety

When the programmer is connected to a vehicle through the OBD connector, follow the manufacturer procedure and use the specified USB powering method. Do not apply an external 12V supply to the programmer during an OBD procedure where the hardware instructions prohibit it.
