ENGINE OIL : InspectionINFOID:0000000001730878
OIL LEVEL AND MUDDINESS
 Before starting the engine, check the oil level placing the vehicle
on a level surface. If the engine is already started, stop it and allow
10 minutes before checking.
 Make sure the oil level is within the range shown.
 If it is out of range, adjust it.
 Check the oil for white turbidity or remarkable contamination.
 If the oil becomes turbid and white, it is highly probable that it is
contaminated with coolant. Find the cause and repair.
OIL LEAKAGE
Check for oil leakage around the following area.
Oil pan
 Oil pan drain plug
 Oil pressure switch
 Oil filter bracket
 Vacuum pump
 Oil pump housing
 Mating surface between cylinder block and cylinder head
 Mating surface between cylinder head and rocker cover
 Oil cooler
 Crankshaft oil seals
OIL PRESSURE CHECK
WARNING:
 Be careful not to burn yourself, as the engine oil is hot.
 Oil pressure check should be done in Neutral “N” position.
1. Check the engine oil level.
2. Remove engine undercover using power tool.
3. Disconnect the electrical connector (A) and remove the oil pres-
sure switch (1) to connect the oil pressure gauge [SST:
KV113E0020 (Mot. 836-05)].
4. After warming up the engine, make sure oil pressure corre-
sponding to the engine speed is produced.
5. After checking, install the oil pressure switch (1) as follows.
a. Remove old sealant adhering to the oil pressure switch (1) and
engine.
b. Apply thread sealant.
Use Genuine Liquid Gasket or equivalent.
6. Start engine and check for oil leakage.

AUTO ACTIVE TEST
Description
In auto active test mode, the IPDM E/R sends a drive signal to the following systems to check their operation.
 Oil pressure low/coolant pressure high warning indicator
 Oil pressure gauge
 Rear window defogger
 Front wipers
 Tail, license and parking lamps
 Front fog lamps
 Headlamps (Hi, Lo)
 A/C compressor (magnetic clutch)
 Cooling fan
Operation Procedure
1. Close the hood and front door RH, and lift the wiper arms from the windshield (to prevent windshield dam-
age due to wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield before hand.
2. Turn ignition switch OFF.
3. Turn the ignition switch ON and, within 20 seconds, press the front door switch LH 10 times. Then turn the
ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test
starts.
5. After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway through test, turn ignition switch OFF.
CAUTION:
• If auto active test mode cannot be actuated, check door switch system. Refer to DLK-65, "
DRIVER
SIDE : Description" (with Intelligent Key system), DLK-499, "DRIVER SIDE : Description" (without
Intelligent Key system).
 Do not start the engine.
