ENGINE OIL PRESSURE GAUGE : System Description

INFOID:0000000007347443

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.

ODO/TRIP METER : System Description

INFOID:0000000007347451

The vehicle speed signal and the memory signals from the meter memory circuit are processed by the combi-

nation meter and the mileage is displayed.

HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER

Refer to Owner's Manual for odo/trip meter operating instructions.

LOOSE FUEL CAP WARNING

The LOOSE FUEL CAP indicator will display in the odometer when the fuel-filler cap is not tightened correctly.

The indicator will turn off as soon as the ECM detects the fuel-filler cap is properly tightened.  The ECM pro-

vides a loose fuel cap signal to the combination meter via CAN communication lines.

CHECK TIRE PRESSURE WARNING

The CHECK TIRE PRESSURE indicator will display in the odometer when BCM has detected a low tire pres-

sure condition.
