SECTION 8 - DIAGNOSTIC TROUBLE CODES
8-6 – JLG Lift – 3121222
006 LIFT UP PREVENTED - MAX
HEIGHT ZONE A
The vehicle has reached the maximum
height and further lift up motion is not pos-
sible. Applicable to 2630ES or 3246ES.
• Check that the zone is set appropriately for the platform load.
• Check that the platform height is at the rated maximum height
specification (20’ for 2630 or 26’ for the 3246).
• Check that the elevation angle sensor is securely mounted.
• If there are any elevation sensor faults (DTC 251, 252, 2511, or
2512), troubleshoot those first.
• Check that ANALYZER -> MACHINE SETUP -> MODEL setting is
correct.
• Check that ANALYZER -> MACHINE SETUP -> MARKET setting
is correct.
• Check ANALYZER -> DIAGNOSTICS -> ELEV SENSOR ->
ZEROED is about 1.53V for the 3246 or about 1.22V for the 2630
when at full height. If not, repair or replace the elevation angle
sensor.
007 DRIVING AT CUTBACK - POT-
HOLE STILL ENGAGED
While stowed, drive speed is reduced
since the control system detected that the
pot-hole protection mechanism failed to
retract.
• Check for obstructions around the pot-hole protection mecha-
nisms.
• Check that the PHP switches are securely mounted.
• Check PHP switches wiring from the ground board and for proper
operation. The left PHP input (24V) is from J1-9 and its output
(24V when deployed) is to J1-10. The right PHP input (24V) is
from J1-17 and its output (24V when deployed) is to J1-18.
008 FUNCTIONS LOCKED OUT -
SYSTEM POWERED DOWN
After 2 hours without activity, the control
system enters a low-power state to pre-
serve battery charge.
• Normal operation should resume after a power cycle.
• Check batteries charge, condition, etc.
009 DRIVE PREVENTED - ELE-
VATED ABOVE DRIVE CUT-
OUT HEIGHT
The platform is elevated above the cali-
brated cutout height.
• Check that the elevation angle sensor is securely mounted.
• Check the ANALYZER -> MACHINE SETUP -> MARKET configu-
ration.
• If MARKET is set to Japan, ensure ANALYZER -> MACHINE
SETUP -> DRIVE CUTOUT parameter is set as desired.
2-1 Power-Up
DTC FAULT MESSAGE DESCRIPTION CHECK
211 POWER CYCLE This help message is issued at each
power cycle. Displays on the analyzer
only.
Normal operation. No check necessary.
212 KEYSWITCH FAULTY Both platform and ground modes are
selected simultaneously. Defaults to
ground mode.
• Check key switch function.
• Backprobe J2-3 with the keyswitch in the ground position. Voltage
should be under 6V. Otherwise, keyswitch or wiring faulty.
• Backprobe J2-4 with the keyswitch in the platform position. Volt-
age should be under 6V. Otherwise, keyswitch or wiring faulty.
• Check key switch wiring to ground board J2-3 and J2-4 and to
emergency stop switch.
•Replace ground board.
2-2 Platform Controls
DTC FAULT MESSAGE DESCRIPTION CHECK
221 FUNCTION PROBLEM -
HORN PERMANENTLY
SELECTED
The horn switch was closed during
power-up in platform mode.
• Check if the horn switch is damaged, obstructed or jammed.
• Disconnect the horn switch ribbon cable on the platform board. If
DTC still present, replace the platform board. If DTC 221 is no
longer present, replace the horn switch or platform board.
