FUEL GAUGE : System Description

INFOID:0000000005275784

The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by the unified meter control unit and a variable resistor signal supplied by the fuel
level sensor unit.

ENGINE OIL PRESSURE GAUGE : System Description

INFOID:0000000005275788

The engine oil pressure gauge indicates whether the engine oil pressure is low or normal.
The oil pressure gauge is controlled by the IPDM E/R. The 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. The oil pressure gauge displays a low or normal indication according to the oil pressure
switch signal received via CAN communication.
