noids, and clutches (Table 2). The component Diagnostics will provide the following routines:
• Input actuation and state change of sensors and switches.
• Turning on and off of Output components (motors, clutches, solenoids, etc.)
• Input test-displays "Test Name" and increments counter. (01, 02, 03 etc.)
• Output test-displays "Test Name" and visual feedback of operation displayed.
