JABS OPERATION AND SERVICE 5 - 43

DEPLOYED
Following an airbag deployment, the vehicle inte-
rior will contain a powdery residue. This residue is
primarily sodium bicarbonate (baking soda), used as
an airbag cushion lubricant. However, there will also
be traces of sodium hydroxide powder, a chemical
byproduct of the generant used for airbag deploy-
ment. Since this powder can irritate the skin, eyes,
nose or throat, be sure to wear safety glasses, rubber
gloves and a long-sleeved shirt during cleanup (Fig.
1).
If you experience skin irritation during
cleanup, run cool water over the affected area.
Also, if you experience irritation of the nose or
throat, exit the vehicle for fresh air until the ir-
ritation ceases. If irritation continues, see a
physician.
CLEANUP PROCEDURE
Remove the airbag and airbag module from the ve-
hicle. Use a vacuum cleaner to remove any residual
powder from the vehicle interior. Clean from outside
the vehicle and work your way inside, so that you
avoid kneeling or sitting on an uncleaned area.
Be sure to vacuum the heater and A/C outlets as
well (Fig. 2). Run the blower on low and vacuum any
powder expelled from the plenum. You may need to
vacuum the interior of the car a second time to re-
cover all of the powder.
Place the deployed airbag and module in your ve-
hicular scrap pile.
AIRBAG MODULE REMOVE/INSTALL
WARNING: THIS AIRBAG SYSTEM IS A SENSITIVE,
COMPLEX MECHANICAL UNIT. BEFORE ATTEMPT-ING TO REMOVE OR INSTALL THE AIRBAG SYS-
TEM OR RELATED STEERING WHEEL AND
STEERING COLUMN COMPONENTS YOU MUST
FIRST DISARM THE AIRBAG FIRING MECHANISM.
FAILURE TO DO SO COULD RESULT IN ACCIDEN-
TAL DEPLOYMENT AND POSSIBLE PERSONAL IN-
JURY.
When removing a deployed airbag module,
rubber gloves, eye protection and long-sleeved
shirt should be worn. There may be deposits on
the airbag module and other interior surfaces,
which can cause irritation to the skin and eyes
in large doses.
(1) Disconnect battery negative cable and isolate.
(2) Using a small screwdriver, remove plastic cover
plug from top outer surface of steering wheel hub.
Exit vehicle and disarm airbag by reaching through
driver's side window and turning arming screw
counter-clockwise to its travel limit. When the screw
has reached its travel limit it will extend 1 inch
above the outer surface of the steering wheel hub
cover. This is done using an 8mm socket and manual
drive. DO NOT USE POWER-DRIVEN TOOLS.
(3) From back side of steering wheel, remove 4
nuts attaching airbag module to steering wheel (Fig.
3). This is done using a 10mm socket and manual
drive. DO NOT USE POWER-DRIVEN TOOLS.
(4) Remove airbag module from steering wheel.
(5) Reverse removal procedures to install. Tighten
airbag module attaching nuts to 9 to 11 Nzm (80 to
100 in. lbs.). Exit vehicle and arm airbag by reaching
through driver's side window and turning arming
screw clockwise to its travel limit. Arming screw
torque should not exceed 1.1 to 1.7 Nzm (10-15 in.
lbs.). Reinstall plastic cover plug in steering wheel
hub.

nal B (driver side) with the positive lead. The volt-
meter should read 10-14 volts.
Steps 3, 4 or 5 above will confirm system operation.
Indicator light illumination means that there is
power available at the output of the switch, but does
not confirm that power is reaching the rear window
grid lines.
If the rear window defogger does not operate, the
problem should be isolated in the following manner:
(1) Confirm that ignition switch is in ON position.
(2) Ensure that the heated rear window feed and
ground wires are connected to the glass. Confirm
that the ground wire has continuity to ground.
(3) Check fuses 8 and 18 (XJ), or fuses 6 and 9
(YJ) in fuseblock module. Fuses must be tight in
their receptacles and all electrical connections must
be secure.
When the above steps have been completed and the
system is still inoperative, one or more of the follow-
ing is faulty:
²defogger switch²relay/timer
²rear window grid lines (all grid lines would have
to be broken or one of the feed wires disconnected for
the entire system to be inoperative).
If turning the switch ON produces severe voltmeter
deflection, check for a short circuit.
REAR WINDOW GLASS GRID
To detect breaks in grid lines, the following proce-
dure is required:
(1) Turn ignition switch to the ON position. Turn
rear defogger switch ON. The indicator lamp should
light.
(2) Using a 12-volt DC voltmeter, contact vertical
bus bar on passenger side of vehicle (point A of Fig.
1) with negative lead of voltmeter. With positive lead
of voltmeter, contact vertical bus bar on driver side of
vehicle (point B of Fig. 1). The voltmeter should read
10-14 volts.
(3) With negative lead of voltmeter, contact a good
body ground point. The voltage reading should not
change. A different reading indicates a poor ground
connection.
(4) Connect negative lead of voltmeter to point A
on passenger side bus bar and touch each grid line at
mid-point with positive lead. A reading of approxi-
mately 6 volts indicates a line is good. A reading of
zero volts indicates a break in the grid line between
mid-point C and point B. A reading of 10-14 volts in-
dicates a break between mid-point C and point A.
Move toward break and voltage will change as soon
as break is crossed.

HOW TO USE THIS GROUP
The purpose of this group is to show the electrical
circuits in a clear, simple fashion and to make trou-
bleshooting easier. Components that work together
are shown together. All electrical components used in
a specific system are shown on one diagram. The feed
for a system is shown at the top of the page. All
wires, connectors, splices, and components are shown
in the flow of current to the bottom of the page. Wir-
ing which is not part of the circuit represented is ref-
erenced to another page/section, where the complete
circuit is shown. In addition, all switches, compo-
nents, and modules are shown in theat rest posi-
tion with the doors closed and the key removed
from the ignition.
If a component is part of several different circuits,
it is shown in the diagram for each. For example, the
headlamp switch is the main part of the exterior
lighting, but it also affects the interior lighting and
the chime warning system.
It is important to realize that no attempt is
made on the diagrams to represent components
and wiring as they appear on the vehicle. For
example, a short piece of wire is treated the
same as a long one. In addition, switches and
other components are shown as simply as pos-
sible, with regard to function only.
The wiring diagram show circuits for all wheel-
bases. If there is a difference in systems or compo-
nents between wheel-bases, an identifier is placed
next to the component.
