Associated Power Module detects that the motor is
rotating in the direction opposite of the com-
manded direction and deceleration is less than
15% of deceleration personality setting for a
period of more than 0.5 seconds
Associated Power Module detects that the motor is

When motor output is active, the Power Module
detects that a motor phase is disconnected/open
during active traction

is not present and either of the external tilt sensor X
or Y axis ? ABS [35 º] for 4 seconds. Not to be
reported during Tilt Sensor calibration.
UGM shall consider the Tilt Sensor stagnant if nei-
ther the X-axis or Y-axis unfiltered reading change
by ≥ ±0.05º in 5000ms while the reported Drive
speed ≥ Drive Creep Hz for all Traction modules
MACHINE SETUP -> LOAD SYSTEM ≠ NO; The UGM
detects that LSS is reporting error with Cell #1
MACHINE SETUP -> LOAD SYSTEM ≠ NO; The UGM
detects that LSS is reporting error with Cell #2
MACHINE SETUP -> LOAD SYSTEM ≠ NO; The UGM
detects that LSS is reporting error with Cell #3
MACHINE SETUP -> LOAD SYSTEM ≠ NO; The UGM
detects that LSS is reporting error with Cell #4
MACHINE SETUP -> LOAD SYSTEM ≠ NO The load
sensor has not been calibrated, or DTC 992 (LSS
EEPROM ERROR) is active, or DTC 9977 (LSS COR-
RUPT EEPROM) is active
