Step 4: Select the Equipment Model

Now, select the correct model, year, and series from the tool’s menu and run a full system scan. This will start the scan and will show you the error codes, monitor parameters, and sensor readings.

Step 5: Check Results

Always check the trouble codes, status and component issues. You can also take a screenshot or export the report for service planning.

Step 6: Clear Codes or Run Tests

Once repairs are done, clear the codes and run actuator tests or calibrations.
