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
