Sensor tests

A dialog listing the sensor tests appears.
3 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.
Motor tests

required. Check the boards and cables for possible issues.
