00-l 6GENERAL - Precautions before Service
Caution
1. Before connecting or disconnecting the negative
cable, be sure to turn off the ignition switch and the
lighting switch.
(If this is not done,there is the possibility of
semiconductor parts being damaged.)
2.For MFI-equipped models, after completion of the
work steps [when the battery’s negative (-) termi-
nal is connected], warm up the engine and allow it
to idle for approximately five minutes under the
conditions described below, in order to stabilize
engine control conditions, and then check to be
sure that the idling is satisfactory.
Engine coolant temperature:
85-95X (185-203°F)
Lights, electric fans, accessories: OFF
Transaxle: neutral position (A/T models: “N” or
“P”)
Steering wheel:neutral (center) position

VEHICLE WASHING
If high-pressure car-washing equipment or steam car-washing
equipment is used to wash the vehicle, be sure to maintain the
spray nozzle at a distance of at least 300 mm (12 in.) from any plastic parts and all opening parts (doors, luggage compart-
ment, etc.).
SCAN TOOL (1) To operate the scan tool, refer to the “Scan Tool Operation Instructions”.
Connection and disconnection of the scan tool should
always be made with the ignition switch in the OFF
position.
(2) Always use a ROM pack that is appropriate for the vehicle.

WRECKER TOWING RECOMMENDATION
FRONT TOWING PICKUP
Caution
This vehicle cannot be towed by a wrecker using sling-type
equipment to prevent the bumper from deformation.
If this vehicle is towed, use wheel lift or flat bed
equipment.
The vehicle may be towed on its rear wheels for extended
distances provided the parking brake is released. It is recom-
mended that vehicles be towed using the front pickup
whenever possible.
REAR TOWING PICKUP
Caution
This vehicle cannot be towed by a wrecker using sling-type
equipment to prevent the axle beam from deformation. If this vehicle is towed, use wheel lift or flat bed
equipment.
Manual transaxle vehicles may be towed on the front wheels,
provided the transaxle is in neutral and the drive-line has not
been damaged. The steering wheel must be clamped in the
straight-ahead position with a steering wheel clamping device
designed for towing service use.
Caution
Do not use steering column lock to secure front wheel
position for towing.
Automatic transaxle vehicle may be towed on the front wheels at speeds not to exceed
50 km/h (30 mob) for a distances not
to exceed 30 km (18 miles).
Caution
If these limits cannot be met, the front wheels must be
placed on a tow dolly.
TOWING WHEN KEYS ARE NOT AVAILABLE
When a locked vehicle must be towed and keys are not available, the vehicle may be lifted and towed from the front.provided the parking brake is released. If not released, the rear
wheels should be placed on a tow dolly.

2.Inspect the wheel cylinder boots for evidence of a brake
fluid leak. Visually check the boots for cuts, tears or heat cracks. (A slight amount of fluid on the boot may
not be a leak, but may be preservative fluid used at
assembly.)
Checking the Brake Shoes for Wear. Thiclkness
of lining (B)
Limit: 1.0 mm
(.04 in.)
14.BRAKEI HOSES (Check for deterioration or
leaks)MOOSBHA
Inspection of brake hoses and tubing should be included in
all brake service operations.
The hoses should be checked for: 1. Correct length, severe surface cracking, pulling, scuf- fing or worn spots. (If the fabric casing of the hoses is
exposed by cracks of abrasion in the rubber hose cover,
the hoses should be replaced. Eventual deterioration of hose may occur with possible bursting failure.)
2. Faulty installation, casing twisting or interference with wheel, tire of chassis.
15.BALL ,IOINT AND STEERING LINKAGE SEALS
(Inspect for grease leaks and damage)
MOOSBJAa
I, These components, which are permanently lubricated at the factory, do not require periodic lubrication.Damaged seals and boots should be replaced to
prevent leakage or contamination of the grease.
2. Inspect the dust cover and boots for proper sealing, leakage and damage. Replace them if defective. 16.DRIVE SHAFT BOOTS (Inspect for grease leaks
and damage) MOOSWAb
1. The.se components, which are permanently lubricated
at the factory, do not require periodic lubrication.
Damaged boots should be replaced to prevent leakage
or contamination of the grease.
2. Inspect the boots for proper sealing, leakage and damage. Replace it if defective.
17.REAR AXLE (Inspect oil level)-AWD MOOSBPQ
Remove the filler plug and inspect the oil level at bottom of
filler hole. If the oil level is slightly below the filler hole, it is
in satisfactory condition. 18.EXHAIJST

(3) If any abnormal noise IS not eliminated by racing, check the
lash adjuster.
@ Stop the engine.
@ Set the engine so that cylinder No. 1 is positioned at
the top dead centre of the compression.
@ Press the rocker arm at the area indicated by the+ arrow mark to check whether the rocker arm is lowered
or not.
@ Slowly turn the crankshaft 360 degrees clockwise.
@ In the same procedure as Step 0, check the rocker
arm at the area indicated by the
0 arrow mark.
@ If the rocker arm lowers easily when the part directly
above the rocker arm lash adjuster is pressed, the lash
adjuster is defective and must be replaced. When re-
placing the lash adjuster, bleed the air from all adjus-
ters and then assemble them. Then inspect with proce-
dures
@ to 0, and confirm that there are no abnormal-
ities
NOTE
lThe lash adjuster can be accurately checked for de-
fects with the leak down test.
l Refer to the engine service manual for the leak down test and lash adjuster air bleeding procedure.
If the rocker arm is extremely hard when pressed
down, the lash adjuster is normal, so look for a different
cause of abnormal sound.
COMPRESSION PRESSURE CHECK
MllFFAL
(1) Before inspection, verify that the engine oil, starter motor and battery are normal. Then, perform the following.
l Engine coolant temperature:
80- 95°C
(176- 203°F)
l Lights, electric cooling fan and accessories: OFF
l Transaxle:
P range
0 Steering wheel: Neutral position
(2) Disconnect the spark plug cable.
(3) Remove all the spark plugs
(4) Disconnect the connector of the distributor.
NOTE
This will prevent the engine control module from controll- ing the ignition and fuel injection.

(5) Cover the spark plug holes with a cloth, etc., and crank the engine. Then verify that no foreign material sticks to the
cloth, etc.
Caution
1. During cranking, be especially careful of the spark plug
installing hole.
2.Very hot water, oil, fuel, etc., which may have entered
the cylinder somehow, will violently spout through the spark plug hole if the compression is measured in the
entrapped state. This is very dangerous.
MANIFOILD VACUUM INSPECTIONMllFNAC
(6)
(7)
(8)
Set up the compression gauge in the spark plug mounting
hole.
Fully open the throttle valve, and cranking the engine,
measure the compression pressure.
Standard value:
<8VALVE>1,250 kPa (178 psi) [250-400 rpm]
< 1 Ei VALVE>
1,300 kPa (185 psi) [250-400 rpm]
Limit:
(8 VALVE>880 kPa (125 psi) [250-400 rpm]
[250-400 rpm]
Measure the compression pressure of each cylinder, and
verify that the pressure difference among the cylinders is
less than the limit value.
Limit: max. 100
kPa (14 psi)
(9) If a cylinder’s compression pressure or pressure difference IS outside
the limit, fill a small amount of engine oil through
the spark plug hole and repeat Items (7) and (8) above.
@ If the compression is increased when the oil is filled, the piston and/or cylinder wall may be worn or
damaged.
@ If the compression is not increased even though the oil is filled, the valve may be thermally seized, the valve
contact may be improper or pressure may leak at the
gasket.
(10) Connect the connector of the distributor.
(11) Install the spark plug and spark plug cable.
(12)Erase the diagnostic trouble code with the Scan tool or re-
connect the battery (-)
cable
10 seconds or more after it
was disconnected.
NOTE
This will erase the memory of the diagnostic trouble code
which
resu,lted from disconnection of the distributor con-
nector.
(1) Before inspection and adjustment, put the vehicle into the
followin~g state.
l Engine coolant temperature:
85-95°C (185-203°F)
l
Ligt-Its, electric, cooling fan, and accessories: OFF
l Transaxle: Neutral
(N or P for vehicles with an automa-
tic transaxle)
l Steering wheel: Neutral position
(2) Check that the idling revolution speed is normal.
