DTC FAULT MESSAGE
251 ELEV ANGLE SENSOR
FAULTY - VOLTAGE OUT OF
RANGE
252 ELEV ANGLE SENSOR HAS
NOT BEEN CALIBRATED
3121166
DESCRIPTION
The trigger switch was closed for more
than five seconds while the joystick was
centered.
The drive and lift inputs are both de-
energized in Platform Mode.
DESCRIPTION
The ground control box lift switch was
closed up or down, during power-up in
ground mode.
The lift up / down inputs are closed simul-
taneously.
The manual brake release switch was
closed during power-up.
DESCRIPTION
The elevation angle sensor input voltage
is outside the acceptable range of 0.10V -
4.50V.
The elevation angle sensor has not been
calibrated.

SECTION 6 - DIAGNOSTIC TROUBLE CODES
CHECK
• Check if the trigger switch is obstructed or jammed.
• Check the trigger switch signal and wiring to the platform board.
The trigger input (24V) is from platform board terminal J1-1, and
its output (24V when closed) is to platform board terminal J1-8.
• Replace platform board.
• Check if either function is active, if Yes;
• Repair the wiring or switch to clear the message.
• ZAPI - HEALTH (Status LED) - ON
CHECK
• Check if the lift switch is obstructed or jammed.
• Check the lift switch signal and wiring to the ground board. The lift
switch input (24V) is from ground board terminal J2-4, and its
outputs (24V when closed) are to ground board terminals J2-6,
J2-7 (up and down).
• Replace ground board.
• Check if the lift switch is obstructed or jammed.
• Check the lift switch signal and wiring to the ground board. The lift
switch input (24V) is from ground board terminal J2-4, and its
outputs (24V when closed) are to ground board terminals J2-6
(up), J2-7 (down).
• Replace ground board.
• Check if the brake release switch is obstructed or jammed.
• Check the brake release switch signal and wiring to the ground
board. The brake release switch input (24V) is from ground board
terminal J1-19, and its output (24V when closed) is to ground
board terminal J1-20.
• If the brakes are released, the machine can be pushed or moved
without drive motor power.
• Replace ground board.
CHECK
• Check that the platform elevation sensor is securely mounted and
undamaged.
• Check voltage as displayed on ANALYZER -> DIAGNOSTICS ->
ELEV SENSOR -> ANGLE SNSR. Backprobe ground board J1-15.
If this voltage disagrees with the ANGLE SNSR voltage, replace
the ground board.
• Backprobe the elevation angle sensor connector. Terminal A
should be 4.7V, terminal C should be 0V.
• Check the elevation angle sensor signal and wiring to the ground
board. The elevation angle sensor input is from ground board ter-
minal J1-14 (4.7V), its output (0.1 - 1.2V when stowed) is to
ground board terminal J1-15, and its ground is to ground board
terminal J1-16.
• Replace the ground board.
• Calibrate the elevation angle sensor to clear fault. See Section 5.5.
