WARNING LAMPSPFP:24814
System DescriptionBKS003R5
OIL PRESSURE WARNING LAMP
Oil pressure warning lamp turns ON when reducing engine oil pressure abnormally.

IPDM E/R inputs oil pressure switch signal from oil pressure switch, and transmits the signal to unified
meter and A/C amp. through BCM with CAN communication.

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

Let the combination meter turn oil pressure warning lamp ON with received oil pressure switch signal.
