Sensor tests

Enter the Diagnostics menu, and then touch Additional input tray diagnostics.

From the Sensor tests section, touch Start.

A dialog listing the sensor tests appears.

Find, and then manually toggle the sensor.

Notes:

• The sensor status on the screen toggles between 1 and 0 when the sensor is properly working.
• If a sensor test fails, the test failure may not indicate a failed sensor. Further troubleshooting may be required. Check the boards and cables for possible issues.
