The TMS374 ECU Decoder is a professional frequency scanner with 5V square wave output (duty cycle 50%, effective frequency range 10kHz to 50Hz), used for decoding and resetting the car ECU to a new state. As the MCU hardware version of the TMS-374 decoding software, it can work independently without a laptop. It supports the anti-theft system decoding of ECU for brands such as Renault (Siemens Fenix 5, Sagem Safir 1/2), Peugeot/Citroën (Magnetti Marelli 1AP series), Hyundai, Kia, Daewoo, Volvo, and is an essential tool for automotive repair and chip tuning fields.
