The High/Low range traction speed switch is located on the console arm
216). When the front of the High/ Low range traction speed switch is depressed,
the traction system will shift to HIGH range traction speed. When the rear of the
High/Low range traction speed switch is depressed, the traction system will shift
to LOW range traction speed.
The master controller monitors the position of the High/ Low range traction
speed switch (high or low). Using inputs from the High/Low range traction
speed switch and other switches in the interlock system, the master controller
communicates the switch position to the slave controller via the CAN network.
The slave controller energizes the hydraulic solenoid valve (SV) located in
the traction hydraulic manifold for high range operation and de−energizes the
solenoid valve for low range operation.
The High/Low range traction speed switch and its circuit wiring can be tested as
TEC inputs using the InfoCenter Display (see
If testing determines that the switch and its circuit wiring are not functioning
correctly, proceed with the following test procedure:
1. Park machine on a level surface, lower cutting decks and stop engine.
Remove key from key switch.
2. Turn battery−disconnect switch to the OFF position.
3. Disassemble the console arm to gain access to the switch (see
Arm (page 7–35)).
4. Disconnect machine wire harness connector from the switch being tested.
