Error Code Problem Solution
ER2
Wheel Angle Calibration Incomplete
The Wheel Angle calibration has not
been completed.
Go to >>Cal>>Wheel Angle, and redo
calibration

Crop Sensor > 4.7V
Description:
The crop sensor is a 5V hall effect
sensor (works like a potentiometer)
that sends an analog voltage to the
Truesight controller. This error is caused
when the analog voltage coming from
the crop sensor is greater than
4.7V.
To read the current voltage, go to
>>Diag>>Overview
>>Crop Sensor
The crop sensor voltage remains stuck
at
4.78 ±0.05 volts when the crop
sensor is moved.
Switch wires A & C in the harness that
connects to the crop sensor to reverse
polarity.
The crop sensor voltage remains stuck
above 4.9 volts when the crop sensor
is moved.
The signal wire (B) may be shorted
to the power wire (C). Find short and
correct.

Crop Sensor < 0.3V
Description:
The crop sensor is a 5V hall effect
sensor (works like a potentiometer)
that sends an analog voltage to the
Truesight controller. This error is caused
when the analog voltage coming from
the crop sensor is less than
0.3V.
To read the current voltage, go to
>>Diag>>Overview
>>Crop Sensor
There is not
5V between pins A & C
of the sensor harness (Unplug sensor
under snout tip to measure)
Unplug square 4 pin Deutsch connection
at feederhouse (Y
703)and measure
voltage between pins 1 & 3 of wire
coming from combine. If
5V is present,
there is a problem with extension
harness under header. If
5V is not
present, continue to follow the wiring
up toward the cab and unplug square
4
pin Deutsch connection Y
7004/Y7003
and measure voltage of pins
1 & 3 of
connector Y
7003. If 5 volts is present
there is a problem with the extension
harness that runs up the feederhouse,
or in the CIH feeder wiring. If
5V is not
present, there is a problem with main TS
harness. Repair or replace appropriate
harness to supply power to sensor.
Sensor is receiving
5V but there is
not 2.5V±1V between pins A & B of
crop sensor (back probe with sensor
centered and harness connected)
Crop sensor failure, replace sensor
Sensor is receiving 5V but there is
not signal voltage on pin 11 of large
connector on Truesight base in cab
(check with back probes, Reference pin
2 for ground)
With crop sensor centered and harness
connected, back probe
4 pin Deutsch
connection at feederhouse (Y703) and
measure voltage between pins 1 & 2. If
2.5V is not present, there is a problem
with extension harness under header.
If
2.5V is present, continue to follow
the wiring up toward the cab and back
probe pins
1 & 2 of the 4 pin Deutsch
connector Y7003. If 2.5V is not present,
there is a problem with the extension
harness that runs up the feederhouse,
or in the CIH feeder wiring. If
2.5V is
present, there is a problem with main TS
harness. Repair or replace appropriate
harness so signal voltage returns to
Truesight
2.
