MACHINE SETUP -> LOAD SYSTEM ≠ NO; The load
sensor has been calibrated and Gross Platform
Weight < (0.5 * Empty Platform Weight)
The UGM observes the Master Traction Module
reported steer raw voltage signal ≥ 4.5V (Constant
Data)
The UGM observes the Master Traction Module
reported steer raw voltage signal ≤0.3V (Constant
Data)
The UGM observes the Master Traction Module
reported steer raw voltage 0.3V < signal < 0.5V
(Constant Data)
The UGM determines that the Master Traction Mod-
ule reported Machine Steer Angle does not change
≥ 1.0° in 4000mS while the steering output is
being commanded while steer is calibrated and
properly reported by MTM in range that is not
within 3deg of calibrated MAX.
UGM determines that the steering sensor has not
been calibrated; UGM EEPROM values are default,
do not match MTM, or UGM fails to successfully read
from memory three times during Startup
UGM determines that an MSSO has occurred
MACHINE SETUP -> LOAD SYSTEM ≠ NO;
UGM detects LSS report of an anomaly exists that
has caused a WatchDog Timer reset.
MACHINE SETUP -> LOAD SYSTEM ≠ NO;
UGM detects LSS report of an anomaly that exists in
the LSS EEPROM
MACHINE SETUP -> LOAD SYSTEM ≠ NO;
UGM detects LSS report of improper excitation
voltage
MACHINE SETUP -> LOAD SYSTEM ≠ NO;
UGM detects LSS report of an anomaly that exists in
the LSS A/D converter operations.
The UGM has detected an anomaly in EEPROM that
can not be auto-corrected from the backup
EEPROM bank.
The UGM software version type is 'P' The UGM has
received valid version information from the PM.
The PM software version type is 'P' The UGM soft-
ware major version number does not match the
major version number of the platform software
MACHINE SETUP -> LOAD SYSTEM ≠ NO;
The UGM determines that the LSS software version
is not compatible with existing code per the refer-
enced Software Version Compatibility table.
Fault Description
Not all of the trigger conditions are met; full func-
tionality permitted after controls initialized
UGM observes steer voltage within calibrated
range for 1000ms;
Drive Creep restriction lifted after fault clears and
controls initialized
UGM observes steer angle voltage within cali-
brated range for 1000ms;
Drive Creep restriction lifted after fault clears and
controls initialized
UGM determines steer angle within allowed
range;
Drive Creep restriction removed after fault clears
and controls initialized;
UGM determines steer angle changes more than
trigger amount while in allowed evaluation
range;
Drive Creep restriction removed after fault clears
and controls initialized
UGM determines that sensor is calibrated
