(d) Using TOYOTA break −out− box and TOYOTA hand− held
tester, measure the ECU terminal values.
(1) Hook up the T OYOTA hand−held tester and TOYO-
TA break−out−box to the vehicle.
(2) Read the ECU input/output values by following the prompts on the tester screen.
HINT:
TOYOTA hand −held tester has a ”Snapshot ” function. This re-
cords the measured values and is effective in the diagnosis of
intermittent problems.
Please refer to the TOYOTA hand−held tester/TOYOTA break
out−box operators manual for further details.
2. SPEED SENSOR SIGNAL AND DECELERATION SEN-
SOR CHECK
(a) Check the speed sensor signal. (1) Conform that the center differential is free.
(2) Turn the ignition switch OFF.
(3) Using SST, connect terminals Ts and E
1 of the
DLC1.
SST 09843−18020
(4) Start the engine.
(5) Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit (See page DI−230).
(6) Drive vehicle straight forward.
HINT:
Drive vehicle faster than 45 km/h (28 mph) for several seconds.
(7) Stop the vehicle.
(8) Using SST, connect terminals Tc and E
1 of the
DLC1.
SST 09843−18020
(9) Read the number of blinks of the ABS warning light.
HINT:
See the list of DTC on page DI−190 .
If every sensor is normal, a normal code is output (A cycle of
0.25 sec. ON and 0.25 sec. OFF is repeated).
If 2 or more malfunction are indicated at the same time, the low-
est numbered code will be displayed 1st.

COMPRESSION
INSPECTION
HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. DISCONNECT DISTRIBUTOR CONNECTOR
3. REMOVE SPARK PLUGS (See page IG−1 )
4. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression pressure.
HINT:
Always use a fully charged battery to obtain engine speed of
250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible. Compression pressure:
1,176 kPa (12.0 kgf/cm
2, 171 psi) or more
Minimum pressure: 883 kPa (9.0 kgf/cm
2, 128 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
If the cylinder compression in one or more cylinders is low, pour
a small amount of engine oil into the cylinder through the spark
plug hole and repeat steps (a) through (c) for cylinders with low
compression.
If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or
damaged.
If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
5. REINSTALL SPARK PLUGS (See page IG−1 )
6. RECONNECT DISTRIBUTOR CONNECTOR

INSIDE VEHICLE
GENERAL MAINTENANCE
The owners are responsible for these maintenance and inspection items.
They can be done by the owner or they can have them done at a service sh\
op.
These items include those which should be checked on a daily basis, thos\
e which, in most cases, do not
require (special) tools and those which are considered to be reasonabl\
e for the owner to do.
Items and procedures for general maintenance are as follows.
1. GENERAL NOTES
Maintenance items may vary from country to country. Check the owner’s manual supplement in which
the maintenance schedule is shown.
Every service item in the periodic maintenance schedule must be performe\
d.
Periodic maintenance service must be performed according to whichever interval in\
the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time inter\
val (months).
Maintenance service after the last period should be performed at the same interval \
as before unless
otherwise noted.
Failure to do even one item can cause the engine to run poorly and incre\
ase exhaust emissions.
2. LIGHTS
(a) Check that the headlights, stop lights, taillights, turn signal lights, \
and other lights are all working.
(b) Check the headlights aim.
3. WARNING LIGHTS AND BUZZERS
Check that all warning lights and buzzers function properly.
4. HORN
Check that it is working.
5. WINDSHIELD
Check for scratches, pits or abrasions.
6. WINDSHIELD WIPER AND WASHER
(a) Check operation of the wipers and washer.
(b) Check that the wipers do not streak.
7. WINDSHIELD DEFROSTER
Check that air comes out from the defroster outlet when operating the heater \
or air conditioner at defroster
mode.
8. REAR VIEW MIRROR
Check that it is mounted securely.
9. SUN VISORS
Check that they move freely and mounted securely.
10. STEELING WHEEL
Check that it has the specified freeplay. Be alert for changes in steering condition, such as hard steering,
excessive freeplay or strange noises.
11. SEATS
(a) Check that all front seat controls such as seat adjusters, seatback recl\
iner, etc. operate smoothly.
(b) Check that all latches lock securely in any position.
(c) Check that the head restraints move up and down smoothly and that the lo\
cks hold securely in any latch position.
(d) For folding −down rear seat backs, check that the latches look securely.
12. SEAT BELTS
(a) Check that the seat belt system such as buckles, retractors and anchors operat\
e properly and smooth-
ly.
(b) Check that the belt webbing is not cut, frayed, worn or damaged.

(6) Check the voltage between the terminals of the Diff.
lock ECU when switching the Diff. lock control
switch with the speedometer, registering approx. 8
km/h (5 mph) or more.
(7) Check that the indicator lights blink when center Diff. lock release mode is set.

rear wheels at this time.
(8) Return the Diff. lock control switch to OFF.
(9) Stop the engine and lower the vehicle.
2. INSPECT DIFF. LOCK SYSTEM CIRCUIT

ON−VEHICLE INSPECTION
1. INSPECT IAC VALVE FOR OPERATING SOUND
Check that there is a clicking sound immediately after stopping
the engine.
If the operation is not as specified, check the IAC valve, wiring
and ECM.
