SECTION 5 - JLG CONTROL SYSTEM
5-20 – JLG Lift– 3121166
9 3 L SS HAS NOT BEEN CALIBRATED 9-3 Flash Cod e
The Load Sensing System’s Calibration EEPROM for
Empty Platform Load is set to Never Set (signature
implanted by the In-Circuit Test Fixture) AND
[Machine
Setup’s LOAD is set to 1=CUTOUT PLT OR 2=CUTOUT
ALL]. Retained until Calibration EEPROM is over-written
by a valid calibration.
Vehicle assumed to be Overloaded.
Calibrate the Load Sensing
System using the calibration
procedure to clear the mes-
sage.
9 9 LSS INTE RNAL ERROR – P IN EXCITATI ON
The Excitation Voltage for the Load Sensors < 4.25V.
9-9 Flash Code
LSS Module Message – Status Message (0x81) is report-
ing “INTERNAL ERROR – PIN EXCITATION < 4.25V” AND
[Machine Setup’s LOAD is set to 1=CUTOUT PLT OR
2=CUTOUT ALL]. Retained until power is re-cycled.
Vehicle assumed to be Overloaded.
The sensors may be exces-
sively loading the Excitation
Supply due to wiring damage,
or the Load Sensing System
Module may have hardware
difficulty.
9 9 L SS INTERNAL ERROR – DRDY MISSIN G FROM
A/D
The DRDY Interrupt from the Load Sensing System Mod-
ule’s A/D Converter is missing.
9-9 Flash Code
LSS Module Message – Status Message (0x81) is report-
ing “INTERNAL ERROR – DRDY INTERRUPT FROM A/
D” AND
[Machine Setup’s LOAD is set to 1=CUTOUT PLT
OR 2=CUTOUT ALL]. Retained until power is re-cycled.
Vehicle assumed to be Overloaded.
This may indicate Load Sens-
ing System Module hardware
difficulty.
9 9 P OWER MODULE FAILURE: PERS ONALITY
RANGE ERROR
The Power Module detected an out-of-range or corrupt
personality setting.
9-9 Flash Code
The Power Module is reporting a “Configuration Range”
Fault Code (11d) OR
a “Configuration CRC” Fault Code
(12d) OR a “Motor Setup” Fault Code (13d). Retained until
power is re-cycled.
Reset control system Person-
alities to default settings to
clear difficulty.
9 9 P OWER MODULE FAILURE: INTE RNAL ERROR
The Power Module detected an internal error via self-test.
9-9 Flash Code
The Power Module is reporting a “Two Direction” Fault
Code (4d) OR
a “Sequence” Fault Code (5d) OR a “CAN-
bus Input” Fault Code (6d) OR a “12V Supply Detection”
Fault Code (18d) OR
a “System Monitor Activated” Fault
Code (24d). Retained until power is re-cycled.
Re-cycle power to clear diffi-
culty.
9 9 P OWER MODULE FAILURE: CHEC K POWER
CIRCUITS OR MOSFET SHORT CIRCUIT
The Power Module detected an error in the Power Wiring
for the Drive or Pump. Alternately, the Power Module has
failed a self-test.
9-9 Flash Code
The Power Module is reporting an “Armature MOSFET
Short Circuit” Fault Code (17d) OR
an “Armature MOS-
FET’s Off” Fault Code (19d) OR
an “Armature MOSFET’s
On” Fault Code (20d) OR
an “Armature Pullup MOSFET
Short Circuit” Fault Code (21d). Retained until power is re-
cycled.
Check wiring and motors or
replace the Power Module.
Re-cycle power to clear diffi-
culty.
