Use this procedure to verify that the ITB is correctly reinstalled.

1.Use the control panel to print the diagnostics pages.

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 1 and 2.
