FUNCTIONS LOCKED OUT -
MACHINE NOT CONFIGURED 9924 The machine is powered up and no model has been selected
yet in the MACHINE SETUP menu Display ??? or NO MODEL at
Analyzer MACHINE SETUP
menu MACHINE SETUP-
>MODEL NUMBER
Do not report any other faults
Disable all machine and
engine functions (i.e., com-
mand engine shutdown and
do not permit start) Power Cycled
GROUND MODULE CONSTANT
DATA UPDATE REQUIRED 9927 The UGM detects one of the following conditions when soft-
ware type is ‘P’ or ‘B’:
The Version Verification Word #1 or the Version Verification
Word #2 values located in the constant data sector of flash
memory (found on constant data spreadsheet tab pstCon-
stantDataVersion) do not match the values located in the code
area of flash memory
The Version Major value located in the constant data sector of
flash memory (found on constant data spreadsheet tab pst-
ConstantDataVersion) does not match the value located in the
code area of flash memory Disable all machine and
engine functions (i.e., com-
mand engine shutdown and
do not permit start) A different application code or constant
data version is programmed so that the val-
ues match
Power Cycled
CURRENT FEEDBACK GAINS
OUT OF RANGE 9944 One or more of the current feedback gains that are calculated
and written to flash memory during the PIC manufacturing
test process are detected as being out of range A gain of 1 is used for the fac-
tory gain(s) that was out of
range; all functions shall be
placed in Creep mode. Power Cycled
CURRENT FEEDBACK CALIBRA-
TION CHECKSUM INCORRECT 9945 The current feedback gains checksum that is calculated and
written to flash memory during the PIC manufacturing test
process is detected as being incorrect Disable all machine and
engine functions (i.e., com-
mand engine shutdown and
do not permit start). Power Cycled
MACHINE CONFIGURATION
OUT OF RANGE – CHECK ALL
SETTINGS 9949 UGM has detected an anomaly in EEPROM with regard to the
Machine Setup configuration. UGM to prompt operator to
correct issue via Analyzer and
disable all machine and
engine functions (i.e., com-
mand engine shutdown and
do not permit start).until
EEPROM data in corrupted
area is changed. Power Cycled and EEPROM data in associ-
ated area is changed
LSS CORRUPT EEPROM 9977 MACHINE SETUP > LOAD SYSTEM ≠ NO;
Load System is the 4-Cell LSS;
and one of the following conditions:
UGM determines LSS-stored values for Unloaded weight in
Indirect 0x100≠ 0x108 or
UGM determines LSS-stored values for Accessory weight in
Indirect 0x102≠ 0x10A
UGM determines LSS-stored checksum1 (0x10F) ≠ checksum
2 (0x107) UGM to set Platform Load
State = Overloaded Power Cycled
FUNCTIONS LOCKED OUT -
GROUND MODULE SOFTWARE
VERSION IMPROPER 9979 Ground software has been installed on a UGM with a
ST10F274 processor (Hardware Rev < 6), which does not have
guaranteed flash storage in the sector where Constant Data is
written. Disable all machine and
engine functions (i.e., com-
mand engine shutdown and
do not permit start) Power Cycled
