ENGINE COOLANT TEMPERATURE GAUGE : System Description

INFOID:0000000005146039

The engine coolant temperature gauge indicates the engine coolant temperature.

The ECM provides an engine coolant temperature signal to the combination meter via CAN communication

lines.

ENGINE OIL PRESSURE GAUGE : System Description

INFOID:0000000005146047

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.
