Reinstall the ITB
Use this procedure to verify that the ITB is correctly reinstalled.
1. Use the control panel to print a Diagnostics page. See the complete version of the English service
manual.
2. Verify that rows one through four, columns A through I (callout 1) contain hexadecimal numbers.
If these rows and columns are all zero, ensure that the calibration sensor was correctly reinstalled.
The sensor must be correctly positioned and fit securely against the chassis before the mounting
screws are installed. See
