Test the parking brake switch (qualifier). If ON
and OFF do not alternate when the parking brake
is engaged and disengaged, the switch or the cir-
cuit wiring for the switch is faulty and should be
tested (see Component Testing in this chapter).
Test the spray pump switch (qualifier). If ON and
OFF do not alternate when the spray pump
switch is engaged and disengaged, the switch or
the circuit wiring for the switch is faulty and should
be tested (see Component Testing in this chap-
ter).
Test the TEC outputs: In this example, the outputs
are OK RUN − TEC output 2, and START − TEC out-
put 1.
OK RUN: When the ignition switch (input) is set to
the RUN position, the OK RUN output should en-
ergize (ON). For gasoline engine machines the
engine ECU ”ignition” should energize, and for
diesel engine machines the fuel stop/run sole-
noid hold coil should energize.
START: When the ignition switch (input) is set to the
START position, the START output should energize
(ON). For gasoline engine machines the engine ECU
“start” should energize, and for diesel engine ma-
chines the start relay and glow controller “start”
should energize and the starter motor should en-
gage.
For gasoline engine machines, the engine ECU is an
output energized by the TEC and therefore cannot
be tested using the InfoCenter procedure. See the
Kubota Workshop and Diagnosis Manual for addi-
tional information.
For diesel engine machines, the fuel stop/run sole-
noid hold coil is an output energized by the TEC and
therefore cannot be tested using the InfoCenter pro-
cedure. Test the fuel stop/run solenoid or start relay
and circuit wiring if necessary (see Component Test-
ing in this chapter). See the Kubota Workshop and
Diagnosis Manual for additional glow controller and
starter motor information.
