SECTION 6 - JLG CONTROL SYSTEM
6-58 – JLG Lift – 3121290
9/9 Flash code 9/9 indicates problems with the controller or the user
disabling safety systems from Access Level 0. 11
PLATFORM MODULE SOFTWARE
UPDATE REQUIRED Platform module code is too old to support the EIM or BPE load sen-
sor and machine is configured to use one of these two sensors. PM
code must be updated to a newer version.
GROUND MODULE CONSTANT
DATA UPDATE REQUIRED Ground module has old constant data that is not compatible with
current ground module software. GM constant data must be
updated to a newer
version. An EMS cycle is required.
HIGH RESOLUTION A2D FAILURE –
INTERRUPT LOST ADS1213 chip in the platform module has stopped asserting its
interrupt (DRDY) line for some reason. An EMS cycle is required.
HIGH RESOLUTION A2D FAILURE-
REINIT LIMIT ADS1213 has needed to be reset 3 or more times. An EMS cycle is
required.
PLATFORM MODULE FAILURE: hwfs
CODE 1 Platform module V(Low) FET has failed. An EMS cycle is required.
GROUND MODULE FAILURE: hwfs
CODE 1 Ground module V(Low) FET has failed. An EMS cycle is required.
GROUND SENSOR REF VOLTAGE
OUT OF RANGE Seven volt reference voltage for joysticks, sensors, etc. is out of
range. Not reported during 2 second power-up. An EMS cycle is
required.
GROUND MODULE FAILURE: hIGH
SIDE DRIVER CUTOUT FAULTY Hardware based high side driver cutout circuit fault. An EMS cycle is
required.
PLATFORM SENSOR REF VOLTAGE
OUT OF RANGE These faults occur when the seven volt reference voltage used for
the joysticks, sensors, etc goes out of range. Not reported during 2
second power-up. An EMS cycle is required.
EEPROM FAILURE – CHECK ALL SET-
TINGS EEPROM critical failure. Personalities, machine configuration digits,
etc may be reset to default values and should be checked. An EMS
cycle is required.
CHASSIS TILT SENSOR NOT GAIN
CALIBRATED Chassis tilt sensor calibration information has been lost. Machine
indicates it is tilted at all times. This calibration data is programmed
into unit at the factory.
CHASSIS TILT SENSOR GAIN OUT OF
RANGE Chassis tilt sensor calibration has become corrupted. This calibra-
tion data is programmed into unit at the factory.
ENVELOPE CONTROL DISABLED Machines with envelope control ONLY. User has forced envelope
control off with analyzer from Access Level 0.
MOMENT CONTROL DISABLED Only occurs on machines with envelope control ONLY. The user has
forced moment control off with the analyzer from Access Level 0.
STEER SENSORS NOT CALIBRATED Machines with a chassis module ONLY. Steer sensors require calibra-
tion.
BOOM SENSORS NOT CALIBRATED Machines with a BLAM module ONLY. Boom sensors require calibra-
tion.
LIFT CRACKPOINTS NOT CALI-
BRATED 1200S and 1350S machines ONLY. Lift valves require a calibration.
TELESCOPE CRACKPOINTS NOT
CALIBRATED 1200S and 1350S machines ONLY. Telescope valves require a calibra-
tion.
DRIVE CRACKPOINTS NOT CALI-
BRATED 1200S and 1350S machines ONLY. Drive valves require a calibration.
