Low Oil Pressure Warning Lamp

Low oil pressure warning lamp is controlled by the IPDM E/R (Intelligent Power Distribution Module Engine Room).

Low oil pressure causes oil pressure switch terminal + to provide ground to IPDM E/R terminal 57. The IPDM E/R then signals the combination meter (unified meter control unit) via the CAN lines and ground is provided to the low oil pressure warning lamp.

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