SYSTEM ANALYSIS
EMM LED INDICATORS
Running
When the outboard is running, all of the LEDs
should be off. If a light is on, check for:
LED 1
– CHARGING FAULT:
•
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
– INJECTOR/IGNITION FAULT:
•
Code 51 – cylinder no. 1 injector circuit open
•
Code 52 – cylinder no. 2 injector circuit open
•
Code 61 – cylinder no. 1 injector circuit short
•
Code 62 – cylinder no. 2 injector circuit short
•
Code 81 – no. 1 ignition primary circuit open
•
Code 82 – no. 2 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, check for 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 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 57 – high RPM with low TPS setting
•
Code 58 – operating temp. not reached
LED 4
– Engine overheat, EMM temperature or
sensor, oil injection pump or sensor, “NO OIL /
OVERHEAT.” For LIGHT ON, check for possible
fault codes:
•
Code 25 – EMM temp. above expected range
•
Code 29 – EMM temp. OVER range (flashing)
•
Code 31 – engine temp. OVER range (flashing)
•
Code 33 – excessive NO OIL faults
•
Code 34 – oil injection pump circuit open
•
Code 43 – temp. above expected range
•
Code 117 – Critical NO OIL detected
