ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and check the engine oil level is within the
range shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE
 Check engine oil for white turbidity or heavy contamination.
 If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following areas:
 Oil pans (lower and upper)
 Oil pan drain plug
 Oil pressure switch
 Oil filter
 Water pump cover
 Oil cooler
 Valve timing control covers (bank 1 and bank 2)
 Mating surface between cylinder head and rocker cover
 Mating surface between front timing chain case and rear timing chain case
 Mating surface between rear timing chain case and cylinder head
 Mating surface between rear timing chain case and cylinder block
 Mating surface between rear timing chain case and oil pan (upper)
 Mating surface between cylinder block and cylinder head
 Crankshaft oil seals (front and rear)
 Camshaft position sensor (PHASE)
OIL PRESSURE CHECK
WARNING:
• Be careful not to get burn yourself, as engine oil may be hot.
 Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to LU-7, "
Inspection".
2. Remove splash guard (RH). Refer to EXT-22, "
FENDER PROTECTOR : Exploded View".

COMBINATION METER
 The combination meter receives the information required to control the operation of each gauge, indicator/
warning lamp, and information display via CAN communication from each unit, each switch, and sensor.
 The combination meter incorporates a trip computer that displays warnings and messages on the informa-
tion display according to the information received from various units.
 The combination meter incorporates a buzzer function that sounds an audible alarm with the integrated
buzzer device. Refer to WCS-5, "
WARNING CHIME SYSTEM : System Description" for further details.
 The combination meter integrates the meter circuit check function and the segment check function that
checks the information display operation.
IPDM E/R
 IPDM E/R reads the ON/OFF signals of the oil pressure switch and transmits the oil pressure switch signal to
the combination meter via BCM with the CAN communication line.
 IPDM E/R is equipped with the diagnosis function. It can perform the operation check of oil pressure warning
lamp with the auto active test and the diagnosis with CONSULT-III.
