Software
Incompatible –
Master
Master TEC
This fault is reported
when the software
within the TEC-5002 is
incompatible with the
software in the other
controllers.
Use Toro DIAG to save the
machine timers and counters
file.
1) Use Toro DIAG to reprogram
the machine.
2) Replace the TEC-5002
controller.
53
SV1 Out
Master TEC
This fault is reported
when the output
current is too high from
the TEC-5002 to the
SV1 hydraulic lift/lower
solenoid.
Use Toro DIAG to save the
machine timers and counters
file.
1) Measure the resistance of the
SV1 coil.
2) Test the wiring harness for SV1
at connector P10.
3) Replace the TEC-5002
controller.
54
SV2 Out
Master TEC
This fault is reported
when the output
current is too high from
the TEC-5002 to the
SV2 hydraulic lift/lower
solenoid.
Use Toro DIAG to save the
machine timers and counters
file.
1) Measure the resistance of the
SV2 coil.
2) Test the wiring harness for SV2
at connector P13.
3) Replace the TEC-5002
controller.
55
SV3 Out
Master TEC
This fault is reported
when the output
current is too high from
the TEC-5002 to the
SV3 hydraulic lift/lower
solenoid.
Use Toro DIAG to save the
machine timers and counters
file.
1) Measure the resistance of the
SV3 coil.
2) Test the wiring harness for SV3
at connector P19.
3) Replace the TEC-5002
controller.
56
SVRV Out
Master TEC
This fault is reported
when the output
current is too high from
the TEC-5002 to the
SVRV (SV4) hydraulic
lift/lower solenoid.
Use Toro DIAG to save the
machine timers and counters
file.
1) Measure the resistance of the
SVRV coil.
2) Test the wiring harness for
SVRV at connector P18.
3) Replace the TEC-5002
controller.
57
Cutting Unit Size
Incompatible
Master TEC
This fault is reported
when the cutting unit
sizes (5-inch and 7-
inch) are mixed.
All cutting unit sizes must match
in cutting units 1–5 before the
machine will function normally
Verify that all 5 cutting units have
the same diameter reel.
58
M/G Current Sensor
Failure
Motor/Generator
controller
One of the 3 current
sensors inside the
motor/generator
