Fault Codes
The list below identifies the fault codes that are gener-
ated by the Toro Electronic Controller (TEC) to identify
an electrical system fault (malfunction) that occurred
during machine operation. Use the InfoCenter Display
to view faults
that have occurred since the faults were
last cleared from the InfoCenter (see Faults Screen in
this chapter)
.
Fault codes 13 through 24 identify problems with TEC
inputs (e.g. switches and senders). For input problems,
use the InfoCenter Display to check the different switch
or sensor positions before testing the component (see
Using the InfoCenter Display for Troubleshooting in this
chapter).
Fault codes 26 through 56 identify problems with TEC
or the outputs energized by the TEC (e.g. relays and so-
lenoids). Output problems may involve issues with the
output device or the portion of the wire harness used to
support the device. Test the component (see Compo-
nent Testing in this chapter), then test the wire harness
(see Electrical Schematics and Wire Harness Drawings
and Diagrams in Chapter 10 − Foldout Drawings in this
manual).

Code
Fault Description Service Suggestions
1 Excessive engine coolant temperature − above
221F (105C) caused reels to disengage Check radiator and screen for debris buildup
Check engine cooling fan and drive belt operation
Check engine coolant level
2 Excessive engine coolant temperature − above
239F (115C) for more than 20 seconds caused
engine to stop
Check radiator and screen for debris buildup
Check engine cooling fan and drive belt operation
Check engine coolant level
3 One of the TEC output fuse is faulty Check fuse F−A1, F−B1, or F−C1 (7.5 Amp)
4 Integrated Programming Environment (IPE)
voltage is low indicating that TEC fuse or TEC is
faulty
Check fuse F−D1 (2 Amp)
Consider that TEC is faulty
5 Main power relay is faulty Test main power relay and circuit wiring
6 Ignition switch was held in the START position for
more than 30 seconds or the ignition switch is
faulty
Cycle ignition switch
Check fuel level in fuel tank
Test ignition switch and circuit wiring
Test fuel pump and circuit wiring
Test fuel stop solenoid and circuit wiring
7 TEC software is incompatible Contact Toro Distributor for reprogramming assis-
tance
8 Charging system voltage is too high Test engine alternator
9 Charging system voltage is too low Check alternator drive belt
Test engine alternator and circuit wiring
10 Engine has not been seen on CAN−bus for
10 seconds (Yanmar diesel engines)
12 InfoCenter has not been seen on CAN−bus for
1 second
13 Ignition switch is faulty Test ignition switch and circuit wiring
14 Engine oil pressure low Check engine oil level
Test oil pressure switch and circuit wiring
