Step 2: Prepare Your Vehicle and Tool
Before diving into ECU programming, you need to make sure your vehicle and tool are prepped for the job:
- Back up your existing software: It’s always a good idea to create a backup of your vehicle’s original ECU software before making any changes.

Step 3: Connecting to the ECU
Now it’s time to connect your Autel scanner to your vehicle’s ECU:
- Locate the OBD-II port: The OBD-II port is typically found under the dashboard on the driver’s side.
- Plug in the Autel scanner: Connect the Autel scanner to the OBD-II port using the provided cable.
- Turn on the ignition: Turn the ignition key to the “on” position.
Step 4: Start the Programming Process
Once you’re connected, follow these steps to start the programming process:
- Select the ECU: Select the ECU you want to program from the Autel scanner’s menu.
- Choose the programming function: The Autel scanner will offer different programming options, such as “reprogramming,” “adaptation,” or “calibration.” Select the appropriate function for your needs.
- Follow the prompts: The Autel scanner will provide clear instructions and prompts to guide you through the programming process.
Step 5: Verify and Complete the Process
After the programming is complete, verify that everything is working properly:
- Check for error codes: Use the Autel scanner to check for any error codes.
- Test your vehicle’s functionality: Drive your vehicle to ensure everything is functioning correctly.
- Document the programming process: Keep a record of the programming process, including the date, time, and version of software used. This will come in handy if you need to revert to the original software or if you need to contact Autel support.
