Traction Pedal Assembly
g257736
Figure 88
The traction pedal assembly includes 2 analog hall effect sensors that do not
require calibration. The sensors operate on 5 VDC supplied by the T1: TEC.
Signal voltage from the pedal sensors are used by the T1: TEC (along with
information from additional inputs) to determine appropriate current flow to the
tandem piston (traction) pump control valves. The sensor signals are also
constantly monitored for traction fault detection.
If a traction pedal fault occurs while the machine is moving, the machine will
slowly come to a stop. The decelerator pedal can be used to stop the machine
sooner if necessary. A traction pedal fault will disable traction control until the
ignition key is cycled OFF and ON.
Testing the Traction Pedal Assembly
The traction pedal assembly and its circuit wiring can be tested as a T1: TEC
input using the InfoCenter Display; refer to
Using the InfoCenter Display for
Troubleshooting (page 3–23)
. If testing determines that the assembly and
its circuit wiring are not functioning correctly, proceed with the following test
procedure:
1. Park the machine on a level surface, lower any attachments and stop the
engine.
2. Disconnect the platform wire harness from the traction pedal. Check the
pedal and the harness connector for damage or corrosion.
3. Connect pins C and D to a 5 VDC power supply, and connect pins B and
E to ground.
4. Using a multimeter (DC voltage setting) with the traction pedal at rest, less
than 0.62 VDC should be present at pin A and less than 0.75 VDC should be
present at pin F.
5. Using a multimeter (DC voltage setting) with the traction pedal fully
depressed, 2.5 VDC should be present at pin A and 4.5 VDC should be
present at pin F.
6. Replace the traction pedal assembly if necessary.
7. If the traction pedal tests correctly and a circuit problem still exists, check the
wire harnesses; refer to
Appendix A (page A–1)
