± BRAKE SYSTEMSERVICE SPECIFICATIONSBR±167

When the negative (±) terminal cable is disconnected from
the battery, memory of the clock and audio systems will be
cancelled. So before starting work, make a record of the con-
tents memorized by the audio memory system. When work
is finished, reset the audio systems as before and adjust the
clock.
This vehicle has power tilt and power telescopic steering,
power seat, power outside rear view mirror and power shoul-
der belt anchorage, which are all equipped with memory
function, it is not possible to make a record of the memory
contents. So when the work is finished, therefore it will be
necessary to explain this fact to the customer, and ask the
customer to adjust the features and reset the memory.
To avoid erasing the memory of each memory system, never
use a back±up power supply from outside the vehicle.
3. Even in cases of a minor collision where the SRS does not
deploy, the steering wheel pad, front passenger airbag
assembly and front airbag sensors should be inspected (See
pages RS±10, 20, 30).
4. Never use SRS parts from another vehicle. When replacing
parts, replace them with new parts.
5. Before repairs, remove the airbag sensors if shocks are likely
to be applied to the sensors during repairs.
6. Never disassemble and repair the front airbag sensors,
center airbag sensor assembly, steering wheel pad or front
passenger airbag assembly in order to reuse it.
7. If the front airbag sensors, center airbag sensor assembly,
steering wheel pad, front passenger airbag assembly or seat
belt pretensioners have been dropped, or if there are cracks,
dents or other defects in the case, bracket or connector,
replace them with new ones.
8. Do not expose the front airbag sensors, center airbag sensor
assembly, steering wheel pad, front passenger airbag
assembly or seat belt pretensioners directly to hot air or
flames.
9. Use a volt/ohmmeter with high impedance (10 k
/V
minimum) for troubleshooting of the electrical circuit.
10. Information labels are attached to the periphery of the SRS
components. Follow the instructions on the notices.
11. After work on the supplemental restraint system is
completed, perform the SRS warning light check (See page
RS±44).
± INTRODUCTIONPRECAUTIONIN±11

Front Airbag Sensor
1. Never reuse the front airbag sensors involved in a collision
that activated the supplemental restraint system. (Replace
both left and right airbag sensors.)
2. Install the front airbag sensor with the arrow on the sensor
facing toward the front of the vehicle.
3. The front airbag sensor set bolts have been anti±rust treated.
When the sensor is removed, always replace the set bolts
with new ones.
4. The front airbag sensor is equipped with an electrical
connection check mechanism. Be sure to lock this
mechanism securely when connecting the connector. If the
connector is not securely locked, a malfunction code will be
detected by the diagnosis system (See page RS±7).
Spiral Cable (in Combination Switch)
The steering wheel must be fitted correctly to the steering col-
umn with the spiral cable at the neutral position, otherwise
cable disconnection and other troubles may result. Refer to
page SR±14 of this manual concerning correct steering
wheel installation.
Steering Wheel Pad (with Airbag)
1. When removing the steering wheel pad or handling a new
steering wheel pad, it should be placed with the pad top
surface facing up.
In this case, the twin±lock type connector lock lever should
be in the locked state and care should be taken to place it so
the connector will not be damaged. In addition do not store
a steering wheel pad on top of another one. Storing the pad
with its metallic surface up may lead to a serious accident if
the airbag inflates for some reason.
2. Never measure the resistance of the airbag squib. (This
may cause the airbag to deploy, which is very
dangerous.)
3. Grease should not be applied to the steering wheel pad and
the pad should not be cleaned with detergents of any kind.
4. Store the steering wheel pad where the ambient temperature
remains below 93°C (200°F), without high humidity and
away from electrical noise. IN±12
± INTRODUCTIONPRECAUTION

5. When using electric welding, first disconnect the airbag
connector (yellow color and 2 pins) under the steering
column near the combination switch connector before
starting work.
6. When disposing of a vehicle or the steering wheel pad
alone, the airbag should be deployed using an SST
before disposal (See page RS±13). Perform the operation
in a safe place away from electrical noise.
Front Passenger Airbag Assembly
1. Always store a removed or new front passenger airbag
assembly with the airbag door facing up. Storing the air-
bag assembly with the airbag door facing down could
cause a serious accident if the airbag inflates.
2. Never measure the resistance of the airbag squib. (This
may cause the airbag deploy, which is very dangerous.)
3. Grease should not be applied to the front passenger airbag
assembly and the airbag door should not be cleaned with
detergents of any kind.
4. Store the airbag assembly where the ambient temperature
remains below 93°C (200°F), without high humidity and
away from electrical noise.
