Description: Engine Crankcase Breather Oil Separator Speed Too Low
Troubleshooting:
DESCRIPTION:
Fault code sets when the engine oil separator speed is less than 3,000 rpm for 45 seconds.
MONITORED PARAMETER:
Crankcase ventilator oil separator speed.
TYPICAL ENABLING CONDITIONS:
Engine coolant temperature greater than 65°C (149°F), Engine oil temperature greater than
65°C (149°F), engine rpm greater than 900 rpm, ambient temperature greater than -8°C (17.6°
F), barometric pressure greater than 10.9 psi (755 mbar).
