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 a lot of time.
LED 1 is top (HIGHEST) LED
IMPORTANT:
and LED 4 is bottom (LOWEST) LED.

1. LED indicators

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 19 – In Gear (tiller models)
•
004197 Code 23 – EMM temp. sensor circuit fault
•
004198
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
•
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
•
