System Self-Test
During engine start-up, pause with the key switch
in the ON position. The horn self-tests by sound-
ing a half-second beep. SystemCheck gauges
self-test by turning the indicator lights on simulta-
neously, then off in sequence.
Service Mode
SystemCheck goes into a service mode if the key
is left ON after self-test (engine NOT running). All
light circuits and sensors are active, but the horn
is not. Grounding the appropriate light circuit wire
will turn the light on, but the horn will not sound.
Refer to SystemCheck CIRCUIT TESTS on
p. 101.
Engine Running
All warning circuits are active when the engine is
running. The horn circuit is active when engine
speed exceeds 500 RPM.
Engine monitor warnings activate the horn for 10
seconds and the appropriate gauge light for a
minimum of 30 seconds. If the failure is momen-
tary (for example, oil moving in the tank), the light
will remain ON for the full 30 seconds before
going out. If the fault continues, the light remains
ON until the key is turned OFF or the failure is cor-
rected. The warning will reoccur at the next start-
up if the problem is not corrected.

S.A.F.E. WARNING
SYSTEM
The S.A.F.E. (Speed Adjusting Failsafe Electron-
ics) warning system alerts the operator and pro-
tects against engine damage from the following
abnormal conditions:
Code 17 Alternator 55 V below expected range
Code 18 Alternator 55 V above expected range
Code 25 EMM temperature above expected
range
Code 34 Oil injector open circuit
Code 40 Engine overheat low speed
Code 43 Cylinder head temperature above
expected range
Code 117 Critical LOW OIL Detected
Code 120 LOW OIL switch open circuit detected
Activation
When one of these conditions occurs, the EMM
interrupts fuel injector and ignition operation,
reducing engine speed to 1200 RPM. The warning
horn sounds and an Engine Monitor message dis-
plays. When S.A.F.E. is active, the engine will run
normally below 1200 RPM. Above 1200 RPM, the
engine will shake excessively.
Recovery
The engine will operate in S.A.F.E. as long as the
fault condition exists. To recover normal operation,
two conditions must be met:
Sensor or switch readings must be back within
limits
The EMM must be reset—stop and restart
