the information. Use of the DIAGNOSTICS screens can
be used to identify and troubleshoot machine electrical
functions.

For  troubleshooting   purposes,   the  DIAGNOSTICS
screens can be used to identify whether aswitch and it’s
circuit wiring are functioning correctly. As an example,
if the ENGINE RUN diagnostic screen is displayed and
the key  switch is in  the RUN position  (ON), the PTO
switch  can  be  engaged  and  disengaged  while  the
screen is viewed. The PTO ENABLED item should indi-
cate the change in status of the PTO switch. If there is
no change  on  the screen  when the  switch  changes
state, a switch or circuit wiring problem should be inves-
tigated.

Additional inputs
Outputs
When the correct inputs are received by the TEC con-
trollers, the  outputs identified  on the  DIAGNOSTICS
screen should show  as ON. If the inputs  are properly
positioned and the output remains OFF, a problem with
TEC controller power (circuit wiring or fuse) or the con-
troller itself should be suspected.
It should be noted that a faulty output component may
not be identified by the DIAGNOSTICS  screen. As an
example, if the  starter solenoid is faulty,  the ENGINE
RUN screen could show that all inputs and outputs are
correct for the function selected. The  controller output
occurs but the  faulty solenoid will  prevent the engine
from starting.
DIAGNOSTICS screens are available for the functions
listed on the following pages.
