C1015
ETR/RTR/OK to
Run - Open The
Circuit
T1
This fault is reported when
an open circuit is detected
on the Engine Control
signal.
The circuit starts at P01
pin 10.
1) Test the wiring for the engine relay coil,
and the resistance of the coil itself.
a) Unplug connector P01, and unplug
Kawasaki harness connector from the
solenoid.
b) Connector P01 pin 10 to ground should
be 70 to 90 ohms.
2) Test the wiring for the solenoid, and the
resistance of the solenoid itself.
a) Unplug connector P01, plug in the
Kawasaki harness connector to the
solenoid, and unplug Toro harness
connector P45 from the engine relay.
b) Connector P01 pin 10 to ground should
be 20 to 30 ohms.
3) Swap the primary controller (T1) with a
known-good unit (includes using Toro
DIAG to save the TD2 file out of the
original TEC-5004, to program the known-
good TEC-5004, and to restore the TD2
file into the final replacement TEC-5004).
C1023
Park Brake
Disengage - Short to
Battery
T1
This fault is reported when
low current is detected on
the automatic Parking
Brake Off signal, indicating
a short to a high (+)
source.
This short could be to
battery voltage or to
another signal that is in a
high state.
The circuit starts at P01
pin 07.
1) Inspect the output circuit wiring and
connectors for damage and corrosion.
2) Test the output circuit wiring.
3) Test the resistance of the brake relay coil
(should be 70 to 90 ohms).
4) Swap the primary controller (T1) with a
known-good unit (includes using Toro
DIAG to save the TD2 file out of the
original TEC-5004, to program the known-
good TEC-5004, and to restore the TD2
file into the final replacement TEC-5004).
