WARNING LAMPS/INDICATOR LAMPS : System Description
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.
