The tool supports ECU operations through the vehicle OBD diagnostic port on selected Toyota and Lexus models.

OBD support includes:

  • Toyota/Lexus 2015+ OBD write on supported models
  • OBD read support on some Toyota/Lexus 2015+ models

This mode is suitable for faster ECU programming work when the vehicle and ECU are supported.

JTAG Mode

For deeper ECU operations, the tool can read and write through the internal ECU connector.

Supported JTAG connection types:

  • Internal 20-pin JTAG connector
  • Internal 26-pin JTAG connector

This gives technicians an additional method when OBD operation is not available or when direct ECU access is required.

Main Applications
