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 Instruction 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.
Unit
Description
Combination meter
Indicates the battery voltage according to the voltage signal received from the fuse block (J/B).
Fuse block (J/B)
Transmits the battery voltage signal to the combination meter.
