1. Never disassemble the steering wheel pad assembly.
2. Do not subject the steering wheel pad to shocks or bring magnets close to it.
3. Do not expose the steering wheel pad to high temperatures or fire.
4. If grease, cleaner, oil or water gets on the steering wheel pad, promptly wipe it off with a dry cloth.
5. Do not drop the steering wheel pad. Never use a steering wheel pad which has been dropped.
6. Never install the steering wheel and pad in another vehicle.
7. When the steering wheel pad is removed, store it on a stable, flat place with the pad surface facing upœ
wards. Never place anything on top of the pad.
8. When work on the vehicle will produce too strong a shock, first loosen the sensor lock release bolt until
it turns freely and perform the work after sensor lock occurs.
9. Even in cases where the vehicle is in a low-impact accident where the airbag is not activated, always
check the pad surface and airbag sensor part. If dents, cracks or deformation is visible, replace the airœ
bag with a new assembly.
10. When disposing of the vehicle or steering wheel, always deploy the airbag first.
11. The deployed inflator inside the steering wheel pad is hot, so dispose of it after it has been cooled by
atmospheric air. Never apply water to cool it down.
2. BRAKE SYSTEM
The brake system is one of the most important safety components. Always follow the directions and
notes given in section BR of the repair manual for the relevant model year when handling brake system
parts.
3. DRIVE TRAIN AND CHASSIS
The drive train and chassis are components that can have great effects on the running performance
and vibration resistance of the vehicle. After installing components in the sections listed in the table
below, perform alignments to ensure correct mounting angles and dimensions. Particularly accurate
repair of the body must also be done to ensure correct alignment.
HINT: Correct procedures and special tools are required for alignment. Always follow the directions
given in the repair manual for the relevant model during alignment and section DI of this manual.

2. SPEED SENSOR SIGNAL CHECK
(a) Check the speed sensor signal.
(1) Turn the ignition switch OFF.
(2) Using SST, connect terminals Ts and E1 of the
DLC1.
SST 09843−18020
(3) Start the engine.
(4) 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−275).
(5) Drive vehicle straight forward.
HINT:
Drive vehicle faster than 45 km/h (28 mph) for several seconds.
(6) Stop the vehicle.
(7) Using SST, connect terminals Tc and E1 of the
DLC1.
SST 09843−18020
(8) Read the number of blinks of the ABS warning light.
HINT:
See the list of DTC shown on the next page.
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 malfunctions are indicated at the same time,
the lowest numbered code will be displayed 1st.
(9) After doing the check, disconnect terminals Ts and
E1, and Tc and E1 of the DLC1, and turn the ignition
switch OFF.
