66
Software Version
Incompatibility
Master
This fault is reported when one
or more of the bus component
controllers (cutting unit
controllers or the S/G controller)
have software that is
incompatible with the TEC
master controller.
The TEC will disable
the engine.
Reprogram the machine using
Toro DIAG.
67
S1 Enable - Current
Too High
Master
This fault is reported when the
TEC determines that the S1 coil
current is too high.
1) Test the circuit wiring to ensure
no short conditions exist.
2) Test the resistance of the
solenoid.
3) Replace the TEC if the harness
and solenoid tests pass and the
fault continuously repeats.
69
Line Contactor -
Overcurrent
Starter/Generator
The S/G controller monitors the
current on both sides of the 48
Vdc contactor. This fault is
reported when the contactor’s
internal current is too high.
The TEC will disable
the cutting units
(PTO), and the
generator will not
provide voltage.
The contactor will not
close.
1) Test the contactor for proper
function
2) Replace the S/G controller if the
fault continuously repeats.
71
S2 Lower – Current
Too High
Master
This fault is reported when the
TEC determines that the S2
solenoid coil current is too high.
1) Test the circuit to ensure no
short conditions exist.
2) Test the resistance of the S2
solenoid.
74
S3 CU2 and CU3 –
Current Too High
Master
This fault is reported when the
TEC determines that the S3
solenoid coil current is too high.
1) Test the circuit to ensure no
short conditions exist.
2) Test the resistance of the S3
solenoid.
76
S4 CU1 – Current
Too High
Master
This fault is reported when the
TEC determines that the S4
solenoid coil current is too high.
1) Test the circuit to ensure no
short conditions exist.
2) Test the resistance of the S4
solenoid.
78
SRV Engage Too
High
Master
This fault is reported when the
TEC determines that the SRV
solenoid coil current is too high.
1) Test the circuit to ensure no
short conditions exist.
2) Test the resistance of the SRV
solenoid.
