NOTICE:
”Cold” and ”Hot” in these sentences express the tempera-
ture of the coils themselves. ”Cold” is from −10°C (14°F) to
50°C (122°F) and ”Hot” is from 50°C (122°F) to 100°C
(212°F).
1. INSPECT IGNITERS AND SPARK TEST
Check that the spark occurs.
(1) Disconnect the high−tension cord (from the ignition
coil) from the distributor cap.
(2) Hold the end approx. 12.5 mm (0.50 in.) from the
body ground.
(3) See if spark occurs while engine is being cranked.
NOTICE:
To prevent gasoline from being injected from injectors dur-
ing this test, crank the engine for no more than 5 − 10 se-
conds at time.
If the spark does not occur, perform the test as follows:

2. INSPECT HIGH−TENSION CORDS
(a) Disconnect the high−tension cords from spark plug.
Disconnect the high−tension cords at the rubber boot. Do
not pull on the high−tension cords.
NOTICE:
Pulling on or bending the cords may damage the conductor
inside.
(b) Disconnect the high−tension cords from ignition coil.
(c) Disconnect the high−tension cords from distributor cap.
(d) Inspect the high−tension cord resistance.
Using an ohmmeter, measure the resistance.
Maximum resistance: 25 kΩ per cord
If the resistance is greater than maximum, check the terminals.
If necessary, replace the high−tension cord.
(e) Reconnect the high−tension cords to distributor cap.
(f) Reconnect the high−tension cord to ignition coil.
(g) Reconnect the high−tension cords to spark plugs.
3. INSPECT SPARK PLUGS
NOTICE:
Never use a wire brush for cleaning.
Never attempt to adjust the electrode gap on a used
spark plug.
Spark plugs should be replaced every 100,000 km
(60,000 miles).
(a) Disconnect the high−tension cords from the spark plugs.
(b) Using a megger (insulation resistance meter), measure
the insulation resistance.
Standard correct insulation resistance:
10 MΩ or more
If the resistance is less than specified, proceed to step (d).
HINT:
If a megger is not available, the following simple method of in-
spection provides fairly accurate results.
Simple Method:
Quickly race the engine to 4,000 rpm 5 times.
Remove the spark plug. (See step (c))
Visually check the spark plug.
If the electrode is dry... OK
If the electrode is wet... Proceed to step (d)
Reinstall the spark plug. (See step (g))

INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.

REPLACEMENT
CAUTION:
Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addi-
tion, used engine oil contains potentially harmful
contaminants which may cause skin cancer.
Care should be taken, therefore, when changing en-
gine oil to minimize the frequency and length of time
your skin is exposed to used engine oil. Protective
clothing and gloves that cannot be penetrated by oil
should be worn. The skin should be thoroughly
washed with soap and water, or use water−less hand
cleaner, to remove any used engine oil. Do not use
gasoline, thinners, or solvents.
In order to preserve the environment, used oil and
used oil filters must be disposed of only at desig-
nated disposal sites.
1. DRAIN ENGINE OIL
(a) Remove the oil filler cap.
(b) Remove the oil drain plug, and drain the oil into a contain-
er.
2. REPLACE OIL FILTER
(a) Using SST, remove the oil filter.
SST 09228−06501
(b) Check and clean the oil filter installation surface.
(c) Lubricate the filter rubber gasket with clean engine oil.
(d) Lightly tighten the oil filter by hand until the rubber gasket
contacts the seat of the filter mounting.

INSPECTION
1. INSPECT RELIEF VALVE
Coat the valve with engine oil and check that it falls smoothly
into the valve hole by its own weight.
If it doesn’t, replace the relief valve. If necessary, replace the oil
pump assembly.
2. INSPECT DRIVE AND DRIVEN ROTORS
3. INSPECT ROTOR BODY CLEARANCE
Using a feeler gauge, measure the clearance between the driv-
en rotor and body.
Standard body clearance:
0.10 − 0.16 mm (0.0039 − 0.0063 in.)
Maximum body clearance:
0.20 mm (0.0079 in.)
If the body clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
4. INSPECT ROTOR TIP CLEARANCE
Using a feeler gauge, measure the clearance between the drive
and driven rotor tips.
Standard tip clearance:
0.04 − 0.16 mm (0.0016 − 0.0063 in.)
Maximum tip clearance:
0.20 mm (0.0079 in.)
If the tip clearance is greater than maximum, replace the rotors
as a set.

1996 RAV4 (RM447U)
INSPECTION
1. INSPECT CENTER DIFFERENTIAL LOCK SYSTEM
(a) Inspect the differential lock operation.
(1) Use a lift or jack stand to lift up the vehicle so that
all 4 tires can rotate.
(2) Apply the parking brake and start the engine.
(3) Set the center differential lock switch to ON.
(4) Depress the clutch pedal and shift into the 2nd gear.
(5) With the engine idling, gradually engage the clutch
and check that the engine stops.
(6) With the parking brake and engine ON, turn the cen-
ter differential lock switch OFF.
(7) Depress the clutch pedal and shift into the 2nd gear.
(8) With the engine idling, gradually engage the clutch
and check that the front wheels rotate.
HINT:
This inspection must be done when the engine is idling.
(b) Inspect the center differential lock indicator operation.
(1) Turn the ignition switch ON.
(2) Check that when the differential lock switch is
turned ON and OFF, the differential lock indicator
lamp lights up and goes off, respectively.
(c) Inspect the center differential lock warning buzzer opera-
tion.
(1) Start the engine and check that the differential lock
warning buzzer does not sound when the center dif-
ferential lock switch is turned ON.
(2) Interchange the solenoid hose No.1 and solenoid
hose No.2 between the differential lock control sole-
noid No.1 and No.2 and the differential lock actua-
tor. And check that the differential lock warning
buzzer sounds when the differential lock switch is
turned OFF.
(3) Return the solenoid hose No.1 and solenoid hose
No.2 to their original location, and check that the dif-
ferential lock warning buzzer stops.
HINT:
Do the inspection with the vehicle stopped.
After finishing the inspection, inspect the differential lock
control solenoid hoses.
