Touch Screen (TS) And Navigation Diagnostics: Notes
Fault codes and diagnostics can be retrieved/achieved using the manufacturer approved diagnostic system
Hard Key Test
The hard key test is used to check the operation of the hard switches.
If switch operation is normal, the switch color on the screen will change when a hard switch is pressed. (Power switch operation cannot be checked on this screen.)
Touch Switch Test
The touch switch test calibrates the touch switch coordinates and checks touch switch operation.
Start Calibration - Calibrates the switch coordinates. Calibrate the coordinates by touching each of the "+" marks in the four corners of the screen.
Touch Switch Check - Checks for deviation in the coordinates. Check the coordinates of the touched location by verifying the displayed values. Touch and hold "press here" to return to the previous screen. If there is a large deviation in the coordinates, calibrate the touch switch using the "Start Calibration" function.
