Verify Diagnostic Display Output Functions
The Diagnostic Display also has the ability to detect
which output solenoids or relays are energized by the
TEC controller(s). This is a quick way to determine if a
machine malfunction is electrical or hydraulic.
NOTE: Anopenoutput(e.g.anunpluggedconnectoror
a broken wire) cannot be detected with the Diagnostic
Display.
1. Park machine on a level surface, lower the cutting
units, stop the engine and engage the parking brake.
2. Remove plate in front of seat to allow access to wire
harness loop--back connector.Locate wire harness and
loop--back connector (Fig. 10). Carefully unplug loop--
back connector from harness connector.
3. ConnecttheDiagnosticDisplayconnectortothehar-
nessconnector.Makesurecorrectoverlaydecal isposi-
tioned on the Diagnostic Display (Fig. 11).
4. Turn the ignition switch to the ON position.
NOTE: The red text on the D iagnostic Display overlay
decal refers to input switches and the green text refers
to TEC outputs.
5. The “outputs displayed
” LED, on lower right column
of the Diagnostic Display, should be illuminated. If “
in-
puts displayed
” LED is illuminated, press the togglebut-
ton on the Diagnostic Display to change the LED to
“outputs displayed
”.
NOTE: It may be necessary to toggle between “
inputs
displayed
” and “outputs displayed” several times toper-
form the following step. To change from inputs to out-
puts, press toggle button once. This may be done as
often as required. Do not press and hold toggle but-
ton.
6. Sit on seat and attempt to operate the desired func-
tion of the machine. The appropriate output LED’s
should illuminate on the Diagnostic Display to indicate
that the TEC controller is turning on that function. The
GLOWPLUGS,HI RANGEandOKRUNoutputs canbe
checked with the ignition switch in the ON position and
the engine not running. For testing of the solenoid out-
puts (e.g. PTO 1, ENABLE, REAR REELS), the engine
must be running.
A. Ifthecorrectoutput LED’sdonot illuminate,verify
that the required input switches arein the necessary
positions to allow that function to occur.
B. If the output LED’s are on as specified, but the
machine does not function properly, suspect a failed
electrical component, an openin thetested circuit or
a non-electrical problem (e.g. hydraulic component
problem). Repair as necessary.
C. If each input switch is in the correct position and
functioning correctly, but the output LED’s are not
correctly illuminated, this indicates a TEC controller
problem. If this occurs, contact your Toro Distributor
for assistance.
7. After output functions testing is complete, discon-
nect the Diagnostic Display connector from the harness
connector and plug loop--back connector into wire har-
ness. Secure access plate to frame.
