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.
For detailed code information, refer to the EMM
Service Code Chart at the back of this manual.
IMPORTANT:
LED 1 is closest to the center of
the EMM (closest to EMM J1-A connector).
Key ON
IMPORTANT:
Diagnostic communications on
non-running rope start models requires that power
is supplied to the
EMM . Refer to Communication
on p. 58.
When the EMM is ON (engine not running), the
following LEDs should light:
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.
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 19 – In Gear (tiller models)
•
Code 23 – EMM temp. sensor circuit fault
•
Code 24 – EMM temp. below expected range
•
Code 41 – temp. sensor circuit fault
•
Code 42 – 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 temperature not reached
•
Code 78 – Sensor supply voltage fault
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
