DIAGNOSTIC TROUBLE CODE CHART
NOTICE:
When removing the part, turn the ignition switch OFF.
When replacing the steering angle sensor or ECU, make sure to perform steering angle sensor
zero point calibration.
HINT:
Using SST 09843-18020, connect the terminals Tc and E1.
If any abnormality is not found when inspecting parts, inspect the ECU.
If a malfunction code is displayed during the DTC check, check the circuit corresponding the code. For
details of each code, refer to the page under respective ºDTC No.º in the DTC chart.

CHASSIS
INSPECTION
1. INSPECT STEERING LINKAGE
(a) Check the steering wheel free-play (See page SR-8).
(b) Check the steering linkage for looseness or damage.
Check that:
Tie rod ends do not have excessive play.
Dust seals and boots are not damaged.
Boot clamps are not loose.
2. INSPECT SRS AIRBAG (See pages RS-15, RS-30)
3. INSPECT STEERING GEAR HOUSING OIL
Check the steering gear housing for oil leakage.
4. INSPECT DRIVE SHAFT BOOTS
Check the drive shaft boots for clamp looseness, leakage or
damage.
5. INSPECT BALL JOINTS AND DUST COVERS
(a) Inspect the ball joints for excessive looseness.
Jack up the front of the vehicle and place wooden
blocks with a height of 180 - 200 mm (7.09 - 7.87
in.) under the front tires.
Lower the jack until there is about half a load on the
front coil spring. Place stands under the vehicle for
safety.
Check that the front wheels are pointing straight
ahead, and block them with chocks.
Using a lever, pry up the end of the lower arm, and
check the amount of play.
Maximum ball joint vertical play: 0 mm (0 in.)
If there is play, replace the ball joint.
(b) Check the dust cover for damage.
6. CHECK TRANSAXLE FLUID
Visually check the transaxle for fluid leakage.
If leakage is found, check for the cause and repair.
7. REPLACE TRANSAXLE FLUID (See page DI-160)

GENERAL MAINTENANCE
These are maintenance and inspection items which are considered to be the owner's responsibility.
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 an 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 including the trunk lid 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.

(d) Place the tires.
(1) Place at least 2 tires under the tire to which the front
passenger airbag assembly is tied.
(2) Place at least 2 tires over the tire to which the front
passenger airbag assembly is tied. The top tire
should have the wheel installed.
(3) Tie the tires together with 2 wire harness.
CAUTION:
Make sure that the wire harness is tight. It is very danger-
ous if loose wire harnesses result in the tires coming free
due to the shock from the airbag deploying.
HINT:
Place the SST connector and wire harness inside tires. Provide
at least 1 m (3 ft) of slack for the wire harness.
(e) Install the SST.
Connect the connectors of the 2 SST to the front passen-
ger airbag assembly connector.

NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock. Also, se-
cure some slack for the SST wire harness inside the tires.
(f) Deploy the airbag.
(1) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the battery negative
(-) terminal.
(2) Check that no one is within 10 m (33 ft) area around
the tire which the front passenger airbag assembly
is tied to.
(3) Press the SST activation switch and deploy the air-
bag.
HINT:
The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.

wheel.
(2) Move the SST to at least 10 m (33 ft) away from the
steering wheel pad tied down on the disc wheel.
(f) Cover the steering wheel pad with a cardboard box or
tires.
Covering method using a cardboard box:
Cover the steering wheel pad with the cardboard
box and weight the cardboard box down in 4 places
with at least 190 N (20 kg, 44 lb).
Size of cardboard box:
Must exceed the following dimensions:
X = 460 mm (18.11 in.)
Y = 650 mm (25.59 in.)
NOTICE:
When dimension Y of the cardboard box exceeds the
diameter of the disc wheel with tire to which the steer-
ing wheel pad is tied, X should be the following size.
X = 460 mm (18.11 in.) + width of tire
If a cardboard box smaller than the specified size is
used, the cardboard box will be broken by the shock
from the airbag deployment.
