6. Press the Menu/Back button (as indicated by the
at the bottom of the screen. Select (highlight) Qualifiers
and press the Left/Right button (as indicated by the
at the bottom of the screen).
NOTE: All of the qualifiers for the machine operation
must be in the desired condition (þ) before the opera-
tion Outputs can be energized.
7. Manually operate each qualifier listed (Fig. 25). The
qualifier condition on the InfoCenter display should al-
ternate þ and ¨ as the qualifiers condition is changed.
If þ and ¨ do not alternate during qualifier operation,
the qualifier component or its circuit wiring is faulty and
should be tested (see Component Testing in this chap-
ter).
CAUTION
It may be necessary to start and run the engine,
raise and lower the cutting units, or otherwise
operate the machine during the troubleshooting
process. Make sure the machine is in a well venti-
lated area and keep away from cutting units and
moving parts while troubleshooting to prevent
personal injury.
In the PTO operation example, the following qualifiers
must be in the desired condition (þ) before any opera-
tion Outputs can be energized:
S
HI/LOW (transport/mow) switch in LOW (mow)
range
S Engine must be running
− engine RPM above 800 as reported by engine
ECU on Yanmar diesel engines
− engine oil pressure switch above minimum
pressure (open) on Kubota diesel engines
S Operator must be in seat (seat switch)
S Engine coolant temperature must be below 220F
(104.4C) (engine temperature sender)
S Cutting units must be lowered below turn−around
position (cutting unit position switch)
If þ and ¨ do not alternate when the qualifier condition
is changed, the qualifier or the circuit wiring for the quali-
fier is faulty and should be tested as described.

9. If all the Inputs are ON and all the Qualifiers are in
their desired condition (þ), the Outputs for the machine
operation should be ON. If the outputs remain OFF, the
Toro Electronic Controller (TEC) or TEC software may
be damaged and require reloading or replacement.
Contact your Toro Distributor for assistance.
10.If the outputs listed on the InfoCenter Display are
ON, and the operation is still malfunctioning:
S Test the specific output and output wiring (see
Component Testing in this chapter).
S Hydraulic components related to the operation
should be tested (see Chapter 5 − Hydraulic Sys-
tem in this manual).
In the PTO operation example, the outputs are the pro-
portional solenoid valve SP1 for the front cutting units
and proportional solenoid valve SP2 for the rear cutting
units. If ON appears next to these outputs on the Info-
Center Display:
S Test the hydraulic solenoid valve coils (see Hy-
draulic Solenoid Valve Coils in the Testing section
of this chapter).
S Perform cutting unit hydraulic circuit tests (see
Chapter 5 − Hydraulic System in this manual).
