WARNING LAMPS
Revision: 2006 November2007 350Z
WARNING LAMPSPFP:24814
System DescriptionNKS00264
OIL PRESSURE WARNING LAMP

Triple meter reads oil pressure signal from oil pressure sensor.

Triple meter judges an oil pressure condition by oil pressure signal, and transmits oil pressure warning
lamp signal to unified meter and A/C amp. with communication line.

Unified meter and A/C amp. transmits oil pressure switch signal to combination meter with communication
line.

Combination meter turns oil pressure warning lamp according to oil pressure switch signal.
