9A-10 SUPPLEMENTAL RESTRAINT SYSTEM

060R300013

Seat Belt with Pretensioner (If so
equipped)
The seat belt comprises a seat belt and a cylinder (a
cylinder filled with powder and an ignition device). In
cases of frontal collision which cause a shock
exceeding a specified level, the controller lets current
flow to the inflation circuit. The current ignites the
cylinder of the seat belt, producing gas. The gas helps
tighten the seat belt to restrain firmly the driver’s upper
half in his seat.




RTW49JSH000201







Steering Column
The steering column absorbs energy and is designed
to compress in a frontal crash to decrease the chance
of injury to the driver.
060R300038

Knee Bolster
The knee bolsters are used to absorb energy to
protect knees and control the forward movement of
the vehicle's front seat occupants during a frontal
crash, by limiting leg movement.

Definitions
Air Bag
An inflatable cloth cushion designed to deploy in
certain frontal crashes. It supplements the protection
offered by the seat belts by distributing the impact load
more evenly over the vehicle occupant's head and
torso.
Asynchronous
Performed in a nonperiodic fashion, (i.e., no defined
time or interval).
B+
Battery voltage, (B+) The voltage available at the
battery at the time of the indicated measurement.
With the key “ON” and the engine not running, the
system voltage will likely be between 12 and 12.5
volts. At idle, the voltage may be 14 to 16 volts. The
voltage could be as low as 10 volts during engine
cranking.
Bulb Check
The SRS control unit will cause the “AIR BAG” warning
lamp to flash seven times and then go “OFF”
whenever the ignition switch transitions to the ON
position from any other ignition switch position and no
malfunctions are detected.

SRS Coil Assembly
Service Precautions
WARNING: SAFETY PRECAUTIONS MUST BE
FOLLOWED WHEN HANDLING A DEPLOYED AI
R
BAG ASSEMBLY. AFTER DEPLOYMENT, THE AIR
BAG ASSEMBLY SURFACE MAY CONTAIN A
SMALL AMOUNT OF SODIUM HYDROXIDE, A BY–
PRODUCT OF THE DEPLOYMENT REACTION,
THAT IS IRRITATING TO THE SKIN AND EYES.
MOST OF THE POWER ON THE AIR BAG
ASSEMBLY IS HARMLESS. AS A PRECAUTION,
WEAR GLOVES AND SAFETY GLASSES WHEN
HANDLING A DEPLOYED AIR BAG ASSEMBLY,
AND WASH YOUR HANDS WITH MILD SOAP AND
WATER AFTERWARDS.
WARNING: WHEN CARRYING A LIVE AIR BAG
ASSEMBLY, MAKE SURE THE BAG AND TRIM
COVER ARE POINTED AWAY FROM YOU. NEVE
R
CARRY AIR BAG ASSEMBLY BY THE WIRES OR
CONNECTOR ON THE UNDERSIDE OF MODULE.
IN THE CASE OF AN ACCIDENTAL DEPLOYMENT,
THE BAG WILL THEN DEPLOY WITH MINIMAL
CHANCE OF INJURY. WHEN PLACING ALIVE AI
R
BAG ASSEMBLY ON A BENCH OR OTHER
SURFACE, ALWAYS FACE BAG AND RIM COVER
UP, AWAY FROM THE SURFACE. NEVER REST A
STEERING COLUMN ASSEMBLY ON THE
STEERING WHEEL WITH THE AIR BAG
ASSEMBLY FACE DOWN AND COLUMN
VERTICAL. THIS IS NECESSARY SO THAT A FREE
SPACE IS PROVIDED TO ALLOW THE AIR BAG
ASSEMBLY TO EXPAND IN THE UNLIKELY EVENT
OF ACCIDENTAL DEPLOYMENT. OTHERWISE,
PERSONAL INJURY COULD RESULT.
NOTE: In the event deployment has occurred, inspec
t
coil assembly wire for any signs of scorching, melting
or any other damage due to excessive heat. If the coil
has been damaged, replace it.

Removal
1. Remove the SRS air bag assembly. (Refer to
“Driver Air Bag Assembly” in this seciton)


2. Remove the steering wheel attachment nut.

060R300009
3. Apply a setting mark across the steering wheel
and shaft so parts can be reassembled in thei
r
original position.
060R300024
4. Move the tires to the straight ahead position before
removing the steering wheel and remove wheel
with 5-8521-0016-0.
5. Feed wiring though the wheel and remove wheel.
6. Remove the steering lower cover and engine hood
opening lever.
7. Remove the driver knee bolster assembly.
8. Remove the steering column cover.
9. Remove air conditioning lower duct.
10.Disconnect the wiring harness connectors located
at the base of steering column.

9A-38 SUPPLEMENTAL RESTRAINT SYSTEM

CAUTION: Never apply force to the steering wheel
in the direction of the shaft by using a hammer o
r
other impact tools in an attempt to remove the
steering wheel. The steering shaft is designed as
an energy absorbing unit.
11. Remove the combination switch assembly with
SRS coil.
NOTE: SRS coil is a part of combination switch
assembly, which cannot be replaced separately.
Therefore, be sure not to remove the SRS coil from
the combination switch assembly.

Installation
1. Install the combination switch assembly with SRS
coil.
2. Turn the SRS coil counterclockwise to full, return
about 3 turns and align the neutral mark.
CAUTION: When turning the SRS coil
counterclockwise to full, stop turning if resistance
is felt. Forced further turning may damage the
cable in the SRS coil.

Legend
(1) Neutral mark

3. Connect the wiring harness connectors located at
the base of steering column.
4. Install the air conditioning lower duct.
5. Install the steering column cover.
CAUTION: When installing the steering column
cover, be sure to wire (through each harness) as
illustrated so that the harness starter switch,
combination switch and SRS coil may not catch
wiring.
825RS048
6. Install the driver knee bolster assembly.
7. Install the steering lower cover and engine hood
opening lever.
8. Install the steering wheel and align the setting
marks.
