SECTION 5 - JLG CONTROL SYSTEM
3121166 – JLG Lift – 5-11
2 2 F UNCTION PROBLEM -- DR IVE & LIFT ACTIV E
TOGETHER
The Drive - Lift selector switch indicates that both functions
are selected simultaneously.
In Platform Mode, the Drive and Lift Digital Inputs are Ener-
gized at the same time. Retained until either is momentarily
De-energized.
Drive, Steer, & Lift Prevented
Repair the wiring or switch to
clear the message.
2 2 F UNCTION PROBLEM -- ST EER LEFT PERMA-
NENTLY SELECTED
Steer left switch in the platform control box was closed dur-
ing power-up.
In Platform Mode, the Left Steer Digital Input Switch is
Energized AND Power-up is Active. Retained until Digital
Input is momentarily De-energized.
Steer & Drive Prevented
Release or repair the switch to
clear the message.
2 2 F UNCTION PROBLEM – STE ER RIGHT PERM A-
NENTLY SELECTED
Steer right switch in the platform control box was closed
during power-up.
In Platform Mode, the Right Steer Digital Input Switch is
Energized and Power-up is Active. Retained until Digital
Input is momentarily De-energized.
Steer & Drive Prevented.
Release or repair the switch to
clear the message.
2 2 A CCELERATOR FAULT Y – WIPER OUT OF
RANGE
The joystick (accelerator) wiper signal input is outside the
acceptable voltage range.
In Platform Mode, the Joystick (accelerator) Analog Input
Switch is > 4.50V OR
< 0.50V. Retained until Analog Input
is measured within proper range.
Drive, Steer, & Lift Prevented.
The wiper wire being off, the
wiper wire shorted to +B, or
the wiper wire shorted to –B
(ground) could cause this diffi-
culty.
2 2 A CCELERATOR FAULT Y – STEER SWITC HES
ACTIVE TOGETHER
Both the steer left and steer right inputs are closed as the
same time.
In Platform Mode, the Steer Left Digital Input is Energized
and the Steer Right Digital Input is Energized. Retained
until either Digital Input is momentarily De-energized.
Drive & Steer Prevented.
A short in the steer switch wir-
ing or a failed steer switch can
cause this difficulty.
2 2 FUNCTION LOCKED OUT – ACCELERATOR NOT
CENTERED
Selected function (drive or lift) is not allowed because the
joystick (accelerator) was not centered at power-up.
In Platform Mode, scaled Joystick (accelerator) position
was something other than 0% AND
Power-up was Active.
Retained until the Joystick is momentarily centered.
Drive, Steer, & Lift Prevented.
Return joystick to center
momentarily and re-initiate.
2 2 F UNCTION PROBLEM – TRIGGER PER MA-
NENTLY CLOSED
Trigger switch in the platform control box was closed at
power-up.
In Platform Mode, the Trigger Digital Input was Energized
AND Power-up was Active. Retained until the Trigger Digi-
tal Input is momentarily De-energized.
Drive, Steer, & Lift Prevented.
Release switch or repair the
switch / wiring to clear the diffi-
culty.
