BATTERY VOLTAGE
TOO LOW –
SYSTEM
SHUTDOWN 441 1 Inhibit all output drivers except
engine start.
The UGM or platform module has
detected the battery voltage is at or
below 9V.
Power cycled.
(Replace/fix
battery.)
BATTERY VOLTAGE
TOO HIGH –
SYSTEM
SHUTDOWN 442 1 Inhibit all output drivers. The UGM or platform module has
detected the battery voltage is at or
above 16V.
Power cycled.
(Fix supply
voltage.)
LSS BATTERY
VOLTAGE TOO
HIGH 443 1 UGM assumes a platform
overloaded condition .
The LSS module detects its supply
voltage is too high and reports the
issue to the UGM.
Power cycled.
(Fix supply
voltage.)
LSS BATTERY
VOLTAGE TOO LOW 444 1 UGM assumes a platform
overloaded condition.
The LSS module detects its supply
voltage is too low and reports the
issue to the UGM.
Power cycled.
(Replace/fix
battery.)
BATTERY VOLTAGE
LOW 445 1 J1-12 Glow-plugs will be inhibited. The UGM has detected the battery
voltage below 11V for a period of 3
seconds or more and an ENGINE
RUNNING state exists.
The UGM
detects the
battery
voltage higher
than 11V for a
period of 10
seconds or
power cycled.
REFERENCE
VOLTAGE OUT OF
RANGE – GROUND 447 1 Inhibit all hydraulic functions. The UGM has detected its
reference voltage is too high or low.
Power cycled.

DRIVE SYSTEM 46XXX
HIGH
TRANSMISSION OIL
TEMPERATURE
CRITICAL 461 1, 11 N/A UGM input J3-11 Transmission Oil
Temperature is LOW when a
TRANSMISSION configuration of
POWERSHIFT or
POWERSYNCRO is selected.
Power cycled.
CONFLICTING
DRIVE DIRECTION
SIGNALS 462 1 Command an ‘N’ in the cabin’s
display.
Broadcast the TC1 J1939 CAN
message on CAN1 to command the
TCM to the neutral gear selection if
MODELS: TH336, TH337, TH406,
TH407, TH414, TH417, TH515 are
configured.
Deactivate and inhibit output J2-33
Transmission Forward.
Deactivate and inhibit output J2-32
Transmission Reverse.
Deactivate and inhibit output J1-1
Reversing Alarm and Lights.
A HIGH signal is detected on more
than one of drive direction inputs
(J4-4 Neutral / J7-22 Forward /
J4-18 Reverse) at the same time for
a period of 3 seconds or more.
Only input
J4-4 Neutral is
HIGH.
