Error Code Problem Solution
ER53
Auto Steering Mode is OFF
Description:
Used with Ontrac3 motor
Ontrac3 motor switch is off Turn switch ON before engaging TS
ER54
Encoder Not Detected:
Description:
The first time Truesight is engaged after
power up, it will throw this error if it has
not received signal from the steering
wheel encoders (steering wheel shaft
rotation sensors).
Encoder has not yet sensed location Turn steering wheel
2 or 3 full turns
The wrong steering system
is selected. To check go to
>>Setup>>Settings>>System
Select the correct steering system
Bad connection in harness See “”ER46 or ER47”” for diagnostics
and solution

Steering Wheel Moving
Description:
For systems that use a hydraulic
pressure transducer for manual
override, a significant change in the
transducer output voltage disengages
the Truesight system. The amount of
change required is measured during
the Auto Deadzone calibration. This
error occurs when the system senses
that the steering wheel is being moved
while trying to engage Truesight.
Steering wheel is being turned while try
to engage system.
Retry engaging Truesight while you are
not turning the steering wheel
Truesight incorrectly senses that the
steering wheel is being turned.
Redo the Auto Deadzone calibration
Wrong system is selected.
If Truesight is tied to an encoder
on the steering column instead
of a pressure transducer, select
the correct steering system. Go to
>>Setup>>Settings>>System
Wiring connection problem (Check by
going to >>Diag>>Disengage
>>Disengage, if voltage is
0.0V there is
probably a wiring problem)
Check wire and connections and fix
problem
Hydraulic pressure transducer problem Contact local dealer to fix or replace
transducer

No 12V or 5V Safety
Description:
Truesight has 2 safety circuits that
need to be satisfied before Truesight
will engage or complete some of the
calibrations.
One or both of the safeties are
not connected (To check go to
>>Diag>>Disengage>>Safeties to check if
they are ""ON"")
Follow installation instructions in this
manual to properly connect safeties
Seat switch is not sensing a person Sit in operators seat before engaging or
calibrating

Outputs are Reversed
Description:
During the Deadzone calibration,
Truesight turns the wheels to learn how
much power it takes to turn them and
what direction they turn. This error
is thrown when the wheels turn the
wrong direction.
Steering system is connected
backwards (Right turns the wheels left
and Left turns the wheel right).
Reverse the steering system if possible
(for example, swap the right and left
solenoid connectors).
Combine received wrong signal during
calibration.
Redo the “Wheel Angle” calibration
and turn the steering wheel all the way
to the right when prompted.
