ENGINE ALARM SYSTEM (CES ENGINES)
The Crusader Challenger engine electronic system is
programmed to control the engine alarm system. Your
CES Engine Alarm System may utilize up to three (3)
alarm circuits to warn you of a potential problem with
your engine.
The alarm circuits have a “self” checking feature
programmed into the system. This feature will
momentarily illuminate the “lamps”, and if equipped,
sound the alarm for two short pulses upon initial start-up
of the engine.
The Malfunction Indicator Lamp (MIL) is used for
notication of any emissions-related fault. This is an
amber indicator lamp, that may be labeled ‘Service
Soon’ or with the ISO icon, to warn the operator of
possible engine problems.
The Check Gauges Lamp (CGL) is used for notication
of any non-emissions-related fault. This is a red
indicator lamp to warn the operator of possible
engine problems such as low oil pressure or an over
temperature condition.
The Buzzer is an audible notication to the operator, that
may be used in conjuction with the MIL and/or CGL.
For events such as an engine over-temperature
condition, low oil pressure, etc., the Buzzer will sound
for 1/2 second ON, 1/4 second OFF, continuously as an
audible warning. For emissions related faults (MIL), the
buzzer will initially sound for 5 seconds, then will sound
for 1/2 second ON once per minute thereafter. In the
event of a MIL circuit failure, MIL circuit functions will be
transferred to the Buzzer circuit.
The alarm circuit has a “self” checking feature
programmed into the system. This feature will light the
“MIL” and “CGL” lamps, and also sound the buzzer for
two short pulses upon initial start-up of the engine.
NOTE: If, during Key ON, engine OFF, either the MIL
or CGL lamps are ashing, this indicates that a stored
trouble code or engine fault is recorded in the ECM.
Refer to your Certied Dealer for proper diagnosis.
If the “MIL” or “CGL” lights and the alarm sounds during
operation, observe the instrument panel readings for
the possible source of the malfunction, such as low oil
pressure or excessive engine temperature readings.
Other conditions that may sound the warning buzzer are
a transmission over-temperature warning (if equipped),
exhaust manifold water over-temperature warning , and
for an electronic throttle malfunction.
IMPORTANT: A failure involving the Electronic Throttle
may result in Idle only operation of the engine. The
operator must obtain service by an authorized Crusader
Challenger Certied Dealer to determine the exact cause
of this malfunction as soon as possible.
In most cases, when the “MIL” or “CGL” lights are on, the
engine may lose some performance and/or eciency,
but remain running adequately. Also, the lights may go
out or become intermittent, but a trouble code will be
logged for future diagnosis.
NOTE: If the MIL is blinking during Key ON, Engine OFF
situation, that means there is a stored diagnostic trouble
code.
In any case, the operator must obtain service by an
authorized Crusader Challenger dealer to determine the
exact cause of the malfunction.
NOTICE: Some boat builders may install their own
alarm system. It is recommended that the boat owner
check with his or her boat dealer for an explanation of
the particular alarm system upon initial delivery.
