OIL PRESSURE WARNING LAMP

The oil pressure warning lamp is controlled by the IPDM E/R (intelligent power distribution module engine

room).

Low oil pressure causes the oil pressure switch to provide a ground signal to the IPDM E/R. The IPDM E/R

then signals the combination meter (unified meter control unit) via the CAN communication lines and ground is

provided to the oil pressure warning lamp.

When power and ground are supplied, the oil pressure warning lamp illuminates.

Unit

Description

Combination meter

Turns the oil pressure warning lamp ON/OFF according to the oil pressure switch signal received 
from BCM by means of communication. 

IPDM E/R

Reads the ON/OFF signals from the oil pressure switch and transmits the oil pressure switch signal 
to the combination meter via BCM with the CAN communication line. 

Oil pressure switch

Refer to 

MWI-48, "Description"

. 

BCM

Transmits the oil pressure switch signal received from IPDM E/R via CAN communication to the 
combination meter via CAN communication.
