Description
T1, T6 12V logic circuit
voltage is below
8.8V (T1), or
48V logic circuit
voltage is below
32V (T6).
T1 The fuse has
failed for outputs
13–16 on the
T1: Primary
controller.
T1 The model
number not
recognized.
T1 The primary
controller
receives a
message
from another
controller on the
CAN bus using
the same source
address.
T1 Multiple cutting
unit motors are
reporting the
same node ID or
address.
T1 CAN
communication
to all 48V
devices is lost.
T1 The T1: Primary
controller never
establishes
or loses
communication
with cutting unit
1 (center).

Check the power supply (fused) to the
controller.
If the fault is generated by the T1:
primary controller, test the 48 VDC/12
VDC converter.
If the fault is generated by the T6:
precharge controller, test the Li-ion
batteries.
Test the 7.5A mini blade style fuse in
the 12V fuse holder (under the right
side cover).
Check the fuse holder circuit wiring
and connector (P68).
Inspect for loose wire or connector.
Test the resistance of the motor ID pin
(pin 2 of the 4-pin motor connector). It
should be 18k to 20k ohm.
Test the resistance of the CAN ID
module.
Verify that the 48V disconnect is
plugged in.
Test the 48V battery voltage.
Test the CAN bus isolation module and
wiring.
Test the 48V logic relay and wiring.
Test the wiring from the cutting unit
motor controller to the CAN bus.
Verify power to the cutting unit.
Swap cutting reel motors between
cutting units. Replace and program
the motor if the fault moves to the new
position (contact an Authorized Toro
Distributor for assistance).
