Electrical Circuit (55 V); Low Oil Warning; No Oil Warning; Cylinder And Crankcase - BRP E250DHLSCS Service Manual

OILING SYSTEM
COMPONENTS
The sensor provides an output voltage to the
EMM based on oil manifold pressures.
5 VDC Input on RED wire
•
0.5 - 4.5 V Output on TAN / WHITE wire
•
Ground on BLACK wire
•
The EMM monitors the oil pressure sensor's elec-
trical circuit. If circuit voltage is beyond the speci-
fied range (< 0.15 V, > 4.85 V), the EMM:
Stores service code 71
EMM LED 3: ON (Running)
If oil pressure is below expected range (< 0.4 V),
the EMM:
Stores service code 72
EMM LED 3: ON (Running)
If oil pressure is above expected range (> 4.6 V),
the EMM:
Stores service code 73
EMM LED 3: ON (Running)
Refer to Oil Pressure Sensor on p. 96.

Electrical Circuit (55 V)

The oil injector is powered by the 55 V electrical
circuit. The EMM controls pump operation by rap-
idly connecting and disconnecting the pump's
internal coil to ground.
The EMM monitors the oil injection pump electri-
cal circuit. If circuit voltage is beyond the specified
range (open circuit), the EMM:
Activates S.A.F.E.
Stores service code 34
EMM LED 4: ON (Running)
Engine Monitor NO OIL display: ON

LOW OIL Warning

A sending unit in the oil tank pick-up assembly
monitors the oil level in the oil tank. This sending
unit turns on the Engine Monitor LOW OIL display
when the oil level falls below one-quarter capacity.
An optional oil tank sending unit kit is available to
display actual oil level through an I-Command net-
work.

NO OIL Warning

The EMM monitors the electrical circuit of the oil
pressure sensor. If the sensor or circuit fails, or if
there is a lack of oil pressure in the oil distribution
manifold, the EMM:
Activates S.A.F.E.
Stores service code 38
EMM LED 4: ON (Running)
Engine Monitor NO OIL display: ON

Cylinder and Crankcase

The primary oil distribution manifold provides
crankcase lubrication through oil distribution
hoses and pressed-in fittings at the front of the
crankcase, port side.
1. Pressed-in fitting
The rear oil distribution manifold provides lubrica-
tion for each cylinder. Each cylinder of the cylin-
der/crankcase has a pressed-in fitting which is
connected to an oil distribution hose.
