DIAGNOSTIC TROUBLE CODE (DTC) 6
PASSENGER AIRBAG DEPLOYMENT LOOP
RESISTANCE IS LOW
Circuit Description
When the ignition switch is turned to ON, the sensing and
diagnostic module(SDM) will perform turn–on test to diag-
nose critical malfunctions within SDM itself.
Upon passing these test ignition and deployment loop volt-
ages are measured to ensure that they are within their nor-
mal voltage ranges. The SDM monitors the voltages at the
driver low and the passenger low to detect shorts to
ground or voltage in the deploy loops.The SDM checks the wiring connection to the passenger
airbag module by letting the infinitesimal current flow
through the internal circuit and verify the resistance.
DTC 6 Will Set When
S The resistance of driver airbag deployment loop is
lower than 1.4 ohms.
S The shorting bar is damaged and then the SDM
must be replaced .

Circuit Description
When the ignition switch is turned to ON, the sensing and
diagnostic module(SDM) will perform turn–on test to diag-
nose critical malfunctions within SDM itself.
Upon passing these test ignition and deployment loop volt-
ages are measured to ensure that they are within their nor-

HANDLING, INSTALLATION AND
DIAGNOSIS
S Airbag modules should not be subjected to temper-
ature above 65 degrees Celsius(149 degrees Fahr-
enheit).
S An airbag and SDM should not be used if it has
been dropped from height of 0.9 meters(3 feet) or
greater.
S When an SDM is replaced, it must be oriented with
the arrow on the SDM pointing toward the front of
the vehicle.
S It is very important for the SDM to be installed flat
on the mounting surface, parallel to the vehicle’s
longitudinal axis.
S To avoid setting diagnostic trouble codes(DTCs), do
not apply power to the SIR unless all components
are connected or a diagnostic chart request it.
S The SIR Diagnostic System Check must be the
starting point of any SIR diagnostics. The SIR Diag-
nostic System Check will verify proper airbag indi-
cator operation and will lead you to correct chart to
diagnose any SIR malfunctions. Bypassing these
procedures may result in extended diagnostic time
incorrect parts replacement.
REPAIRS AND INSPECTIONS
REQUIRED AFTER AN ACCIDENT
CAUTION : Any repairs to the vehicle’s structure
must return it to the original production configu-
ration. Deployment requires replacement of
SDM, the inflator modules and a dimensional in-
spection of the steering column.
S If any SIR components are damaged, they must be
replaced. If SIR components mounting points are
damaged, they must be repaired or replaced.
S Never use SIR parts from another vehicle. This
does not include remanufactured parts purchased
from an authorized source.
S Do not attempt to service the SDM, the clock spring
or other airbag modules, these items must be re-
placed if they are defective.
S Verify the part number of replaced airbag modules.
Some inflator modules look identical but contain
different internal components.

FRONT SEAT BELT
PRETENSIONERS
CAUTION : Tempering with seat belt pretensioner
creates the risk of an injury from unexpected deploy-
ment. Therefore, the driver airbag module should
never be disassembled.
The seat belt pretensioners(with load limiter for some ve-
hicles) are assembled with each front seat belt retractors
to retract the seat belt webbing when accounted frontal
collision. The seat belt pretensioners are controlled by
sensing and diagnostic module(SDM). The seat belt pre-
tensioner contains an igniter charge and a gas generator
to pull the seat belt webbing. The seat belt pretensioner
must be replaced after an accident that causes its activa-
tion.
The seat belt pretensioner also contains a shorting bar to
prevent current from travelling through the seat belt pre-
tensioner during servicing. The shorting bar is disengaged
when the connector is connected.
SENSING AND DIAGNOSTIC
MODULE (SDM)
CAUTION : During the service procedures, be careful
when handling the SDM. Never shake or jar the SDM.
Never apply power to SIR when the SDM is not rigidly
attached to the vehicle. All SDM mounting bolts and
grounding nuts must be fully tightened. Failure to fol-
low these precautions could cause deployment and
result in personal injury.
The SDM is located on the floor beneath the floor console
assembly. The SDM performs the following functions :
S Monitors the supplemental inflatable restraints(SIR)
electrical components and sets a diagnostic trouble
code(DTC) when malfunction is detected.
S Records any faults that are discovered.
S Displays SIR diagnostic trouble codes and system
status information when connected to a scan tool.
S Illuminates the airbag indicator to alert the driver to
any fault.S Provides a reserve power source to deploy the air-
bags and pretensioners if an accident has disabled
the normal power source.
S Monitors vehicle velocity changes to detect frontal
impacts, which are severe enough to warrant de-
ployment.
S Causes current to flow through the airbag modules
and pretensioner to cause deployment if a frontal
impact of sufficient force is detected.
The SDM contains no user–serviceable parts.
AIRBAG WARNING LAMP
The instrument cluster contains an airbag warning indica-
tor and sensing and diagnostic module(SDM). The SDM
performs a turn–on test when the ignition is turned ON.
The SDM flashes the airbag indicator seven times by sup-
plying an intermittent ground to the indicator lamp circuit.
After flashing seven times, the airbag indicator will turn off
if no more malfunctions have been detected.
If the SDM has detected malfunctions in the internal and
external circuits, which could potentially affect the opera-
tion of the supplemental inflatable restraints(SIR), the air-
bag indicator stays on. Some malfunctions could result in
non–deployment when necessary or deployment under
conditions which would not normally result in deployment.
When the SDM is not properly attached to its connector,
the airbag circuit is shorted to ground because there is a
shorting bar in the SDM electrical connector. The shorting
bar is disengaged when proper connection is made, but if
a poor connection exists the SDM connector supplied a
ground to the airbag indicator independently of the SDM,
and the airbag indicator turns on.
CLOCK SPRING
CAUTION : Disassembling the clock spring can cause
injury or cause the clock spring to malfunction.
CAUTION : Over–rotating the clock spring (over 3 and
one quarter turns to one direction) without the steer-
ing wheel in position could damage the clock spring
and result in an inoperative driver airbag.
There is a coil assembly in the steering which is referred
to as a clock spring because of its internal resemblance to
the type of spring used in a mechanical clock. The coil

GENERAL DESCRIPTION
AND SYSTEM OPERATION
CIGAR LIGHTER
The cigar lighter is located in the front portion of the floor
console. To use the lighter, push it in completely. When the
lighter is hot, it will release itself from contact with the heat-
ing element. The lighter and the heating element can be
damaged if the lighter is not allowed to release itself fully
from the heating element.
ASHTRAY
The ashtray is located below the audio system. To access
the ashtray, pull it out from the center console. The ashtray
lamp will go on when the parking lamps or the headlamps
are turned on.
INSTRUMENT PANEL VENTS
The center and the side vents in the instrument panel can
be adjusted up and down and from side to side. The side
vents can also be aimed toward the side windows in order
to defog them.
GLOVE BOX
The glove box can be opened by pulling up on the latch
handle. The glove box must be removed in order to gain
access to the passenger’s side airbag module.
DIGTAL CLOCK
The digital clock is located in the instrument panel, above
the audio system. The clock is capable of a 12–hour or a
24–hour display.
INSTRUMENT CLUSTER
The instrument cluster is located above the steering col-
umn and in the instrument cluster trim panel. The instru-
ment cluster contains the instruments that provide the
driver with vehicle performance information. The instru-
ment cluster contains a speedometer, an odometer, a trip
odometer, a temperature gauge, a fuel gauge, and several
indicator lamps. For replacement of the indicator lamp
bulbs contained in the instrument cluster, refer to ”Instru-
ment Cluster Indicator Lamps Specifications” and”Instru-
ment Cluster Indicator Lamps” in this section.
SPEEDOMETER/ODOMETER/TRIP
ODOMETER
The speedometer measures the speed of the vehicle in
km/h (mph in some countries). It consists of an instrument
cluster gauge connected to the vehicle speed sensor
(VSS) on the transaxle output shaft.The odometer measures in kilometers (miles in some
countries) the total distance the vehicle has traveled since
it was manufactured. It consists of an instrument cluster
gauge connected to the VSS on the transaxle output shaft.
The trip odometer measures the distance the vehicle has
traveled since the odometer was last reset. It consists of
an instrument cluster gauge connected to the VSS on the
transaxle output shaft. The trip odometer can be reset to
zero at any time so that the driver can record the distance
traveled from any starting point.
FUEL GAUGE
The fuel gauge consists of an instrument cluster gauge
connected to a sending unit in the fuel tank.
The fuel gauge indicates the quantity of fuel in the tank
only when the ignition switch is turned to ON or ACC.
When the ignition is turned to LOCK or START, the pointer
may come to rest at any position.
TEMPERATURE GAUGE
The temperature gauge consists of an instrument cluster
gauge connected to a temperature sensor that is in con-
tact with the circulating engine coolant.
The temperature gauge indicates the temperature of the
coolant. Prolonged driving or idling in very hot weather
may cause the pointer to move beyond the center of the
gauge. The engine is overheating if the pointer moves into
the red zone at the upper limit of the gauge.
INSTRUMENT CLUSTER INDICATOR
LAMPS
The instrument cluster contains indicator lamps that indi-
cate the functioning of certain systems or the existence of
potential problems with the operation of the vehicle. The
indicator lamps are replaceable. For replacement of the in-
dicator lamps contained in the instrument cluster, refer to
”Instrument Cluster Indicator Lamps Specifications”
and”Instrument Cluster Indicator Lamps” in this section.
CHIME MODULE

fuse block and will sound in order to bring attention to one
or more of the following conditions:
S The lamps are on, the door is ajar, and the ignition
switch is not in ACC, ON, or START.
S The seat belt is unbuckled when the ignition switch
is in ON or START.
S The door is open when the ignition switch is in ON
or START.
S The key is left in the ignition switch when the igni-
tion is in LOCK and the door is open.
