Testing the Traction Pedal Position Sensor (continued)
2. Ensure the traction pedal assembly is able to move from full forward stop
to full rearward stop.
3. Use the InfoCenter to view the sensor signal voltage:
A. Sit in the operator seat and set the key switch to the O
N
position.
B. Set the function control switch to the N
EUTRAL
position.
C. From the InfoCenter Main Menu, select
Diagnostics > Traction > Inputs
.

(shown with traction pedal fully forward)
D. Move the traction pedal forward.
Pedal Fwd
should be checked.
E. Move the traction pedal fully forward.
Pedal Sig 1
should be 3.75 – 4.50
V and
Pedal Sig 2
should be 0.50 – 2.55 V.
F. Move the traction pedal rearward.
Pedal Rev
should be checked.
G. Move the traction pedal fully rearward.
Pedal Sig 1
should be 0.50 – 2.55
V and
Pedal Sig 2
should be 2.55 – 3.20 V.
H. Allow the traction pedal to return to the N
EUTRAL
position.
Pedal Sig 1
and
Pedal Sig 2
should be 2.55 – 3.20 V.
I.
Set the key switch to the O
FF
position.
4. If any of the sensor readings are out of range, test the traction position sensor:
A. Disconnect the machine wire harness from the traction pedal position
sensor. Check the sensor and the harness connector for damage or
corrosion and clean or repair as necessary.
B. Connect the sensor pins C and D to a 5 VDC power supply, and connect
pins B and E to ground.
C. Using a multimeter (DC voltage setting) with the traction pedal in the
N
EUTRAL
position, 2.55 – 3.20 VDC should be present at both sensor
pins A and F.
D. Using a multimeter (DC voltage setting) with the traction pedal depressed
fully forward, 3.75 – 4.50 VDC should be present at sensor pin A and 0.50
– 2.55 VDC should be present at sensor pin F.
E. Using a multimeter (DC voltage setting) with the traction pedal depressed
fully rearward, 0.50 – 2.55 VDC should be present at sensor pin A and
2.55 – 3.20 VDC should be present at sensor pin F.
