SYSTEM ANALYSIS
EMM LED INDICATORS
EMM LED INDICATORS
The
EMM
LED indicators provide a quick refer-
ence to the status of several outboard systems.
Checking the LEDs FIRST when diagnosing an
engine problem can save time.
IMPORTANT:
LED 1 is toward the top of the
outboard (closest to EMM J2 connector).
Key ON
When the
EMM
is ON (engine not running), the
following LEDs should light:
LED 1
– SAC Circuit working – 30 V present on
55 V circuit.
LED 3
– Sensor Circuits working. FLASHING
LIGHT indicates Code 57 – engine will not start.
LED 4
– Stop Circuit not grounded–okay to start.
FLASHING LIGHT indicates severe overheat or
no oil – engine in SHUTDOWN mode.
Starting
Starting mode occurs from the time the flywheel
begins to turn
until the outboard is running for 2
seconds. During starting, all four LEDs should
light and then go off in sequence.
LED 1
– CHARGING OKAY – Stator signal 30 V
or higher. For NO LIGHT, check for:
•
SAC circuit problem
LED 2
– CRANK POSITION OKAY – input from
CPS,
EMM
powered ON. For NO LIGHT, check
for:
•
Code 16 – CPS, intermittent loss of sync
LED 3
– SENSORS OKAY (5 V). For NO LIGHT,
check for:
•
Code 12 – TPS circuit fault
•
Code 13 – TPS below expected range
•
Code 14 – TPS above expected range
•
Code 23 –
EMM
temp. sensor circuit fault
•
Code 24 –
EMM
temp. below expected range
•
Code 37 – Water in fuel
•
Code 41 – Port temp. sensor circuit fault
•
Code 42 – Port temp. below expected range
•
Code 47 – AT sensor circuit fault
•
Code 48 – AT sensor below expected range
•
Code 49 – AT sensor above expected range
•
Code 58 – Operating temp. not reached, port
•
Code 59 – Operating temp. not reached, stbd
•
Code 67 – Stbd temp. sensor circuit fault
•
Code 68 – Stbd temp. below expected range
•
Code 78 – 5V sensor circuit overload
•
Code 87 – Exhaust pressure circuit fault
•
Code 88 – Exhaust pressure low
•
Code 89 – Exhaust pressure high
For FLASHING LIGHT, check for Code 57.
LED 4
– LANYARD/STOP OKAY. For NO LIGHT,
check for:
•
Grounded stop circuit.
For FLASHING LIGHT, check for:
•
Code 29 –
EMM
temp. OVER range (flashing)
•
Code 31 – Engine temp. OVER range (flashing)
•
Code 33 – Engine shutdown, excessive no oil
condition
