OIL PRESSURE WARNING LAMP
 IPDM E/R reads the ON/OFF signals from the oil pressure switch and transmits the oil pressure switch sig-
nal to the combination meter via BCM with the CAN communication line.
 The combination meter turns the oil pressure warning lamp ON/OFF according to the oil pressure switch sig-
nal received via CAN communication.
