Two pressure sensors are used to monitor the traction circuit hydraulic pressure
when the machine is moving in the forward direction. The pressure sensor for
the front axle motor circuit is located on the left side of the tandem piston pump,
and the pressure sensor for the rear axle motor circuit is located on the right side
of the tandem piston pump. The T1: TEC uses information from the sensors to
assure each traction pump (front and rear) is doing the same amount of work
based on system pressure. The sensor signals are constantly monitored for
fault detection.
A pressure sensor fault will disable the cruise control and PTO, and the machine
will be forced to stop. Once the traction pedal is returned to the rest position,
the machine will operate in limp home mode (reduced ground speed and PTO
disabled) until the ignition key is cycled OFF and ON.
Testing the Pressure Sensors
The pressure sensors and their 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 a sensor 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.
Note:
Remove the right fender to gain access the rear axle pressure sensor.
2. Disconnect the wire harness connector from the sensor and clean any
corrosion from the sensor and wire harness connector contacts.
3. Test the machine wire harness to the pressure sensor:
A. Set the key switch to the RUN position.
B. Navigate to the InfoCenter Traction Inputs screen and scroll down to
display the Front Traction and Rear Traction readings.
