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 shop.
These items include those which should be checked on a daily basis, those which, in most cases, do not
require (special) tools and those which are considered to be reasonable 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 performed.
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 interval (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 increase exhaust emissions.
2. TIRES
(a) Check the pressure with a gauge.
If necessary, adjust.
(b) Check for cuts, damage or excessive wear.
3. WHEEL NUTS
When checking the tires, check the nuts for looseness or for missing nuts.
If necessary, tighten them.
4. TIRE ROTATION
Check the owner’s manual supplement in which the maintenance schedule is shown.
5. WINDSHIELD WIPER BLADES
Check for wear or cracks whenever they do not wipe clean.
If necessary, replace.
6. FLUID LEAKS
(a) Check underneath for leaking fuel, oil, water or other fluid.
(b) If you smell gasoline fumes or notice any leak, have the cause found and corrected.
7. DOORS AND ENGINE HOOD
(a) Check that all doors and the tailgate operate smoothly, and that all latches lock securely.
(b) Check that the engine hood secondary latch secures the hood from opening when the primary latch
is released.

7. HYDRAULIC TEST
Measure the line pressure.
NOTICE:
Do the test at normal operation fluid temperature 50 − 80°C (122 − 176°F).
The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
Be careful to prevent SST’s hose from interfering with the exhaust pipe.
(1) Warm up the fluid.
(2) Remove the test plug on the transmission case right side and connect SST.
(See page AT−26 and AT−33 for the location to connect SST)
SST 09992−00094 (09992−00150, 09992−00270)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Start the engine and check idling speed.
(5) Keep your left foot pressed firmly on the brake pedal and shift into D position.
(6) Measure the line pressure when the engine is idling.
(7) Depress the accelerator pedal all the way down. Quickly read the highest line pressure when
engine speed reaches stall speed.
NOTICE:
Release the accelerator pedal and stop test if the rear wheels begin to rotate before the engine speed
reaches specified stall speed.
(8) In the same manner, do the test in R position.

DTC P0770 Shift Solenoid E Malfunction
(Shift Solenoid Valve SL)
SYSTEM DESCRIPTION
The ECM uses the signals from the Throttle position sensor,
mass air flow meter and crankshaft position sensor to monitor
the engagement condition of the lock−up clutch.
Then the ECM compares the engagement condition of the
lock−up clutch with the lock−up schedule in the ECM memory
to detect mechanical trouble of the shift solenoid valve SL,
valve body and torque converter clutch.
DTC No.DTC Detecting ConditionTrouble Area
P0770
Lock−up does not occur when driving in the lock−up range
(normal driving at 80 km/h [50 mph]), or lock−up remains ON
in the lock−up OFF range
(2 trip detection logic)Shift solenoid valve SL is stuck open or closed
Valve body blocked up or stuck
Lock−up clutch
INSPECTION PROCEDURE
1 Check solenoid valve SL operation.
PREPARATION:
(a) Remove the oil pan.
(b) Remove the shift solenoid valve SL.
CHECK:
(a) Applying 490 kPa (5 kgf/cm2, 71 psi) of compressed air,
check that the solenoid valve does not leak air.
(b) When battery voltage is supplied to the shift solenoid
valve, check that the solenoid valve opens.
NG Replace solenoid valve SL.

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
2. REMOVE INTAKE AIR CONNECTOR
(See page EM−65)
3. DISCONNECT HIGH−TENSION CORDS FROM
SPARK PLUGS
NOTICE:
Pulling on or bending the cords may damage the conductor
inside.
4. REMOVE SPARK PLUGS
5. 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:
1,230 kPa (12.5 kgf/cm
2, 178 psi) or more
Minimum pressure:
880 kPa (9.0 kgf/cm
2, 127 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
(e) 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, chances are
that the piston rings and/or cylinder bore are worn
or damage.
If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
