worn or damaged parts)
15
Engine Speed
Switch Broken
Master TEC
This fault is reported
when the TEC detects
an engine speed
increase signal and an
engine speed decrease
signal at the same
time.
The engine speed (throttle)
switch may be shorted
internally, or the outputs of the
switch may be shorted together.
Engine rpm will not vary when
this fault exists.
1) Test the engine speed switch.
2) Test the engine speed switch
wiring.
24
Joystick Broken
Master TEC
This fault is reported
when the joystick
switch is broken or
shorted internally.
The rear switch under the
joystick is used to lower (and
engage) the cutting units. The
front switch is used to raise
(and disengage) them.
1) Test the joystick switches.
2) Test the joystick circuit wiring.
26
Engine Start
Output Signal
Current is Too
High
Master TEC
This fault is reported
when the current from
the TEC (that is used
to energize the starter
relay coil) is higher
than 5 amps.
• If the fusible link connected
to the starter motor is faulty,
all electrical power to the
machine (including the
InfoCenter) is shut off.
• If you replace the TEC, use
Toro DIAG to save the
machine timers and
counters file.
1) Use the InfoCenter to test the
engine start output signal.
2) Test the start relay.
3) Test the engine start output
signal wiring at OUT 1.
4) Replace the TEC controller.
27
Engine Run
Output Circuit
Fault to Fuel
Actuator
Master TEC
This fault is reported
when the engine run
output circuit from the
TEC is supplying more
than 5 amps to the fuel
actuator.
• If a problem occurs with the
fuel actuator, the engine
mechanical governor will
control engine speed above
high idle (3,150 rpm).
• If you replace the TEC, use
Toro DIAG to save the
machine timers and
counters file.
1) Test the fuel actuator.
2) Test the wiring for the fuel
actuator and the fuel pump.
3) Test the engine start output
signal wiring at OUT 2.
4) Replace the TEC controller.
37
TEC Output
Current to Glow
Plug Relay is
Excessive
Master TEC
This fault is reported
when the TEC output
current to energize the
glow plug relay
exceeds 5 amps.
If you replace the TEC, use
Toro DIAG to save the machine
timers and counters file.
1) Test the glow relay.
2) Test the glow relay wiring
harness at OUT 3.
3) Replace the TEC controller.
