TSD Diagnostics
The TSD has built-in diagnostics to aid in technician
diagnosis of system faults. The following functions are
available:
• Hard key function
• Touch screen function
• Video input
• RGB video
• Vehicle signals
• Self-test
• Configurations
• Vehicle configurations
• MOST ring function.
Built-in diagnostics are accessed as follows:
– Once the system is powered up, enter the Home menu.
– Press and hold the TSD in the center at the top of the
screen for approximately 5 seconds and then press the
navigation hard key.
– A Diag PIN Entry box will appear; type in the access
code 753.
– Once this code has been accepted the Diagnostic Menu
screen will be displayed.
Hard Key Test Screen
The hard key test is used to determine the function of the
two switches integrated into the TSD. Pressing either of
the buttons will turn the corresponding icon on the screen
green if it is functioning correctly.
Touch Screen Test Screen
Entering the Touch screen test screen allows the technician
to test the physical side of the touch screen. The technician
can choose between checking screen integrity and
recalibrating the screen. Using the Touch Switch Check
button will display a blank screen. Touching the screen
in any place will give a series of coordinates. If a faulty
area of the screen is touched the coordinates will not
display.
Recalibrating the screen allows the technician to align the
touch screen coordinates to the pressing of the screen.
This is achieved by pressing a series of on-screen targets.
