3. Airbag Module
A: REMOVAL AND INSTALLATION
CAUTION:
IThe airbag module (driver, passenger and
side) must not be disassembled. The airbag
module cannot be used again once inflated.
G5M0299
IWhen removing and installing the airbag
module (driver, passenger and side), the opera-
tor should stand, as much as possible, on the
side of the airbag module.
G5M0300
IAfter removal, the airbag module (driver,
passenger and side) should be kept away from
heat and light sources, and stored on a clean,
flat surface to prevent from any damage to its
lower structure.
G5M0301
IDo not check airbag module (driver, passen-
ger and side) continuity with airbag removed
from the vehicle body.
G5M0302
IReplace airbag module (driver, passenger
and side) with a new one, should any of the
following conditions develop:
IPad surface is scratched or cracked.
IConnector harness is damaged.
IInflator side structure of module is
cracked or deformed.
IModule is excessively stained with water,
oil, etc.
IModule was accidentally dropped.
IThe front seat assembly is damaged or
deformed.
IThe removed front seat with the airbag mod-
ule must be kept on its back. At this time, keep
the module side at least 200 mm (7.87 in) away
from walls or other objects.
B5M0515A
IWhen storing a removed airbag module
(driver and passenger), be sure to place it in
parallel with floor with the pad facing up. Do
not place it against a wall, or place anything on
the pad; otherwise, a dangerous condition may
be created if the module malfunctions.

5. Airbag Control Module
A: REMOVAL AND INSTALLATION
CAUTION:
IDo not disassemble the airbag control mod-
ule.
G5M0322
IIf the airbag control module is deformed, or
if water damage is suspected, replace the air-
bag control module with a new genuine part.
G5M0323
IAfter removal, keep the airbag control mod-
ule on a dry, clean surface away from heat and
light sources, and moisture and dust.
G5M0324
1) Turn ignition switch off.
2) Disconnect ground cable from battery and wait
for at least 20 seconds before starting work.3) Remove lower cover.
Disconnect airbag connector (AB3) and (AB8)
below steering column.
CAUTION:
Do not reconnect airbag connector at steering
column until airbag control module is securely
re-installed.
G5M0312
4) Remove console box.
5) Disconnect connector from airbag control mod-
ule.
6) Using TORX
TBIT T40 (Tamper resistant type),
remove two TORXTbolts. Discard the old TORXT
bolts.
CAUTION:
Use new TORX
Tbolts during re-assembly.

E: INSPECTION
Check electrodes and inner and outer porcelain of
plugs, noting the type of deposits and the degree
of electrode erosion.
G6M0086
1) Normal
Brown to grayish-tan deposits and slight electrode
wear indicate correct spark plug heat range.
G6M0087
2) Carbon fouled
Dry fluffy carbon deposits on insulator and elec-
trode are mostly caused by slow speed driving in
city, weak ignition, too rich fuel mixture, dirty air
cleaner, etc.
It is advisable to replace with plugs having hotter
heat range.
G6M0088
3) Oil fouled
Wet black deposits show excessive oil entrance
into combustion chamber through worn rings and
pistons or excessive clearance between valve
guides and stems. If same condition remains after
repair, use a hotter plug.
G6M0089
4) Overheating
White or light gray insulator with black or gray
brown spots and bluish burnt electrodes indicate
engine overheating. Moreover, the appearance
results from incorrect ignition timing, loose spark
plugs, wrong selection of fuel, hotter range plug,
etc. It is advisable to replace with plugs having
colder heat range.
