The parking brake latch switch is a normally open proximity switch. This switch
is 1 of the several inputs for the TEC. The switch is attached to the handle
assembly switch panel
When the parking brake latch is released, the latch is positioned near the target
end of the parking brake latch switch so that the switch is closed. The parking
brake latch is moved away from the switch when the latch is engaged causing
the switch to be in its normally open state.
Check the operation of parking brake latch switch with the InfoCenter on the
console. With the key switch in the R
diagnostics menu, choose the P Brake Latch and ensure that the switch state
changes as the parking brake latch is engaged and released. Further parking
brake latch switch testing is necessary only if the switch state does not change
when using the InfoCenter.
1. Park the machine on a level surface and place the traction lever in the
N position. Turn the key switch to the O
EUTRAL
key from the key switch.
2. Disconnect the battery pack; refer to
(page 5–7).
3. Remove the console cover from the handle to get access to the parking
brake latch switch
4. Disconnect the parking brake latch switch connector from the machine wire
harness.
5. Connect a multimeter (ohms setting) across the switch connector terminals
to check the continuity of the parking brake latch switch.
6. With the parking brake released, there should be continuity (zero ohms)
across the switch terminals.
7. Check that the switch opens (infinite ohms) as the parking brake latch is
engaged.
