Toyota Denso Gen1 ECUs with no NBD / JTAG pads

The latest Toyota Denso Gen1 ECUs with MCU NEC 76F0085 are built in small metallic cases and don't have NBD/JTAG pads to perform the reading.

It is still possible to write them over OBD but you have to obtain the original file somehow. Here are the possible ways to do that:

  • Extract it from a CUW update file
  • Solder the MCU to another ECU that has NBD/JTAG pads and read it from there
  • Virtual reading

The virtual reading can be performed with BitBox's Toyota Denso Gen1 CAN plugin that currently offers the following original files:
