DIAGNOSTICS
LED Indicators
The
EMM
has LED indicators located next to the
electrical connectors that provide information
related to various electrical circuits.
Starting Mode
“Starting mode” occurs from
EMM
power ON until
outboard is running for 2 seconds.
LED 1
– Stator signal 30 V or higher, “CHARGING
OKAY.” For NO LIGHT, investigate possible fault
codes: 17, 18, 26, 27.
LED 2
– Crankshaft position sensor output,
EMM
powered (ON), “CRANK POSITION OKAY.” For
NO LIGHT, investigate possible fault code 16.
LED 3
– Sensor circuits (5 V), “SENSORS OKAY.”
For NO LIGHT, investigate possible fault codes:
12, 13, 19, 24, 16, 19, 32, 41, 42, 44, 45, 46, 47,
48, 49, 58.
For FLASHING LIGHT ON, investigate code 57
(High RPM with low TPS setting)
LED 4
– Lanyard/Stop circuit not grounded, “LAN-
YARD/STOP OKAY.”
For NO LIGHT, repair grounded stop circuit.
For FLASHING LIGHT ON, investigate possible
fault code 29 (engine shutdown,
EMM
overheat),
code 31 (engine shutdown, engine overheat) or
code 33 (engine shutdown, excessive no oil con-
dition).
Running Mode
LED 1
– Low charging output, “CHARGING
FAULT.” For LIGHT ON, investigate possible fault
codes:
•
Code 17 – system voltage (55 V) below range
•
Code 18 – system voltage (55 V) above range
•
Code 26 – low battery (12 V) voltage
•
Code 27 – high battery (12 V) voltage
LED 2
– Damaged injector circuit, ignition primary
circuit, or fuel pump circuit, “INJECTOR/IGNITION
FAULT.” For LIGHT ON, investigate possible fault
codes:
•
Code 51 – cylinder no. 1 injector circuit open
•
Code 52 – cylinder no. 2 injector circuit open
•
Code 53 – cylinder no. 3 injector circuit open
•
Code 61 – cylinder no. 1 injector circuit short
•
Code 62 – cylinder no. 2 injector circuit short
•
Code 63 – cylinder no. 3 injector circuit short
•
Code 81 – no. 1 ignition primary circuit open
•
Code 82 – no. 2 ignition primary circuit open
•
Code 83 – no. 3 ignition primary circuit open
•
Code 91 – fuel pump circuit open
•
Code 94 – fuel pump circuit short
LED 3
– Sensor circuits (5 V), “SENSOR FAULT.”
For LIGHT ON, investigate possible fault codes:
•
Code 12 – TPS circuit fault
•
Code 13 – TPS below expected range
•
Code 14 – TPS above expected range
•
Code 16 – CPS, intermittent loss of sync
•
Code 32 – oil switch signifies constant pressure
•
Code 41 – engine temp. sensor circuit fault
•
Code 42 – engine temp. below expected range
•
Code 44 – BP sensor circuit fault
•
Code 45 – BP below expected range
•
Code 46 – BP above expected range
•
Code 47 – AT sensor circuit fault
•
Code 48 – AT sensor below expected range
•
Code 49 – AT sensor above expected range
•
Code 58 – engine not reaching operating temp.
