Do you need a tool for complete ECU management in JTAG mode? DFOX is the perfect professional tool for you!
DFOX is a professional solution for the mechatronics engineer to read and program ECUs via JTAG MODE systems, supporting low-level processor communication.

Working in JTAG MODE with DFOX

The JTAG MODE system is for low-level communication with the ECU processor.

It can prove particularly useful when:

  • the ECU has the bench mode locked by the parent company, but you still want to read the entire contents of the ECU
  • a corrupt file was previously written
  • the ECU is not set up for bench mode: in this case it is possible to work with the ECU open

Before programming the vehicle ECU, DFOX calculates and corrects the Checksum/RSA/CVN of the file and performs the necessary checks on the file to avoid any risk.

Use the flat cables provided in the kit.

This will allow you to read and operate on the entire contents of the control unit.
