Oil Pressure Warning Lamp

Oil pressure warning lamp turns ON when reducing engine oil pressure abnormally.

• IPDM E/R reads 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.
• Combination meter turns oil pressure warning lamp ON with received oil pressure switch signal.
