Parking Brake Switch
POSITION
CLOSED
CIRCUITS
ON
OFF
The parking brake switch is located on the main instrument panel. Push down on
the top of the switch to engage the parking brake (switch light illuminated) and
push down on the bottom of the switch to disengage the parking brake.
The T1: TEC monitors the position of the parking brake switch. The parking
brake is spring loaded and engages automatically when hydraulic pressure is
not present. When the engine is running and the parking brake switch is set to
the OFF position, the T1: TEC energizes the hydraulic solenoid valve (SV2) to
pressurize the brake circuit and disengage the brake.
Testing the Parking Brake Switch
The parking brake switch 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 switch and 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 battery negative (-) cable at the battery.
3. Remove the instrument panel from the dash.
4. Disconnect the wire harness connector from the switch and remove the
switch from the instrument panel if necessary.
5. Use a multimeter (ohms setting) and the preceding table to determine
whether continuity exists between the various terminals for each switch
position.
6. The switch indicator light can be tested by applying (+) 12 VDC to terminal 8
and a (-) ground to terminal 7.
7. Replace the switch if necessary.
8. If the switch tests correctly and a circuit problem still exists, check the wire
harnesses; refer to
Appendix A (page A–1)
.
9. Install the switch, connect the wire harness and install the instrument panel
after testing.
10. Connect the battery negative (-) cable at the battery.
