ENGINE MANAGEMENT MODULE (EMM)
The EMM activates the warning horn and gaug e
displays as follows:
LOW OIL means that oil in the tank is at reserve
•
level (about 1/4 full).
NO OIL indicates the oil tank is empty.
•
WATER TEMP or HOT ind icates an engine or
•
EMM overheat condition.
CHECK ENGINE or FAULT is used to ind icate
•
other fault conditions identified by the EMM.
Refer to the EMM Service Code Chart at the
back of th is manual for a co mplete list of all fault
codes.
System Self-Test
During engine start-up, pause with the key switch
in the ON position. The horn se lf-tests by sound-
ing a ha lf-second beep . SystemCheck g auges
self-test by turn ing the indicator lights on simu lta-
neously, then off in sequence.
Note: The warning horn does NOT sound in an
I-Command installation.
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. Ground ing the appropriate light circuit wire
will turn the light on , but the ho rn will no t sound.
Refer to SystemCheck CIRCUIT TESTS on
p. 107.
Engine Running
All warning circuits are active wh en the eng ine is
running. Th e horn circu it is active when engin e
speed exceeds 500 RPM.

Engine monitor warnings activate the horn for 1 0
seconds and the appro priate gauge light for a
minimum of 30 secon ds. If the failure is mome n-
tary (for example, oil moving in the tank), the light
will remain ON for t he full 30 seconds befo re
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.
