5. The "INPUTS DISPLAYED" LED, on lower right col-
umn of the Diagnostic Display, should be illuminated. If
the green "OUTPUTS DISPLAYED" LED is illuminated,
press the toggle button on the Diagnostic Display to
change to "INPUTS DISPLAYED" LED.
6. The Diagnostic Display will illuminate the LED
associated with each of the inputs when that input is in
the position identified on the Diagnostic Display overlay.
Individually, change the position of each of the inputs
(i.e. sit on seat, press traction pedal, etc.), and note that
the appropriate LED on the Diagnostic Display toggles
on and off when the input state is changed (see Diag-
nostic Display Inputs and LED Operation chart on next
page). Repeat for all inputs that can be changed by
hand.
7. If appropriate LED does not toggle on and off when
input state is changed, check all wiring and connections
to the switch for that input and/or test switch (see Com-
ponent Testing in this chapter). Replace all defective
switches and repair any damaged wiring.
Electrical System
NOTE: The ALT FAULT TEC controller input cannot be
reliably tested by grounding the harness leads at the al-
ternator. If the alternator is faulty, a TEC controller fault
should have been detected. Refer to Diagnostic Light in
this section for information on retrieval and clearing of
TEC controller faults.
NOTE: When the ignition switch is in the OFF position,
all Diagnostic Display LED's should be OFF.
8. After input function testing is completed, disconnect
the Diagnostic Display from wire harness. Plug loop-
back connector into harness connector. Lower and se-
cure seat.
