1. Unzip the wiring diagram package followed by the driver package.
Initiate the STM32 driver depending on your computer system (XP, Win7, Win8, or Win10). Choose the appropriate version (64 for a 64-bit system and X86 for a 32-bit system) and proceed with the installation by double-clicking “Install”.
2. Connecting the Device:
Open the application and navigate to “options”, then select “port”. Note: The device COM port will appear if the driver installation is successful.
Click “open” to establish a successful device connection.
3. Utilizing the Wiring Diagram
Important: The number displayed on the Denso engine exterior might not be accurate. The reliable method is to open the board and refer to the number noted on the computer chip.
For instance, if the ECU number is 2750363410, open the wiring diagram and select the corresponding ECU number, which will also display the chip CPU number (76F0070 in this case) as illustrated in the wiring diagram.
4. Setting Up the Connection
Step 1: Utilize the two cables from the Toyota ECU Flasher to connect to the engine socket. Establish a connection with a ground wire and a live wire to power the engine ECU.
