DESCRIPTION
Driving is not possible since the
platform is elevated and the
chassis is not level.
The vehicle has reached the
maximum height and further lift
up motion is not possible. Appli-
cable to 2632ES or 3246ES.
While stowed, drive speed is
reduced since the control sys-
tem detected that the pot-hole
protection mechanism failed to
retract.
After 2 hours without activity,
the control system enters a low-
power state to preserve battery
charge.

SECTION 6 - DIAGNOSTIC TROUBLE CODES
CHECK
• Check that the machine is tilted. If so, lower the plat-
form and reposition the machine to a level surface.
• Fully stow the platform.
• The tilt sensor is part of the ground control box. Check
that the ground control box is secured to the
machine.
• Check that the pothole protection switches are
securely mounted.
• Check that the elevation angle sensor is securely
mounted.
• Check the ANALYZER -> MACHINE SETUP -> MARKET
configuration.
• If MARKET is set to CE, ensure ANALYZER -> MACHINE
SETUP -> TILT CUTOUT parameter is set as desired.
• Check pothole protection switch adjustment.
• Backprobing ground board J1-18 should show about
0 volts.
• Backprobing ground board J1-10 should show about
0 volts.
• Calibrate the elevation sensor, see Section 5.5.
• Calibrate the tilt sensor, see Section 5.2.
• Check that the zone is set appropriately for the plat-
form load.
• Check that the platform height is at the rated maxi-
mum height specification (20' for 2632 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 2632 when at full height. If not, repair or replace
the elevation angle sensor.
• Check for obstructions around the pot-hole protec-
tion mechanisms.
• 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.
• Normal operation should resume after a power cycle.
• Check batteries charge, condition, etc.
