LOW ENGINE OIL
PRESSURE
WARNING 4318 1, 2, 9 N/A The ECM detects the engine oil
pressure is getting low, the ECM will
transmit a J1939 CAN bus DM1
message, or use the J1939 Transfer
Protocol in the event multiple
engine faults exist, on CAN1 to
communicate low engine oil
pressure (SPN:FMI 100:17 or
100:18).
Power cycled.
LOW ENGINE OIL
PRESSURE
CRITICAL 4319 1, 2, 3, 9 N/A MECHANICAL: The UGM detects
input J12-8 Engine Oil Pressure is
LOW for 3 seconds and an ENGINE
RUNNING state exists for a period
of 5 seconds.
ELECTRONIC: The engine oil
pressure reaches its critical low oil
pressure value, which is based on
engine speed, the ECM will transmit
a J1939 CAN bus DM1 message, or
use the J1939 Transfer Protocol in
the event multiple engine faults
exist, on CAN1 at a rate of 1 second
to communicate low engine oil
pressure (SPN:FMI 100:1).
Power cycled.
ALTERNATOR
CHARGING
FAILURE 4320 1, 2, 10 N/A Once an ENGINE RUNNING state
exists for a period of 3 seconds or
more, J4-7 Alternator D+ input will
be LOW for a period of 500ms.
J4-7
Alternator D+
is continu-
ously HIGH
for a period of
3 seconds.
AIR FILTER
RESTRICTION 4321 1, 2, 7 N/A J1-34 Air Filter Restriction input is
LOW and an ENGINE RUNNING
state exists for a period of 3
seconds or more or 10 seconds
after a system power up.
J1-34 Air
Filter
Restriction
input is HIGH
for 1 second.
LOSS OF ENGINE
SPEED SIGNAL 4322 1, 2 Deactivate J2-26 Engage Starter.
Ignore the above-mentioned
interlock for disabling the
Continuous Auxiliary Hydraulics
function when engine speed is 600
RPM.
Ignore the prevent engine stall
logic.
MECHANICAL: J4-7 Alternator D+
is HIGH and J12-8 is HIGH and no
impulses are received at J1-16
Engine Speed.
ELECTRONIC: The TCM or ECM
will report the fault using J1939
CAN protocol to the UGM.
Power cycled.
CONFLICTING
OPERATING
ENGINE STATE 4324 1, 2 N/A J4-8 Engine Start has been
engaged during the active power
cycle, an ENGINE STOPPED
condition exists, and one of the
three ENGINE RUNNING
conditions is true
Power cycled.
