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.

NOTE:
When ignition key warning chime and light warning chime should be performed at the same time, the priorities
for each chime are the following.
1. Light warning chime
2. Ignition key warning chime
IGNITION KEY WARNING CHIME (WITHOUT INTELLIGENT KEY)
With the key inserted into the ignition switch, and the ignition switch OFF or ACC, when driver's door open, the
warning chime will sound.
Power is supplied

through key switch terminal 4

to BCM terminal 37.
Ground is supplied

to BCM terminal 62

through front door switch (driver side) terminal 2.
