DESCRIPTION AND OPERATION
DRIVER SEAT BELT WARNING
The driver’s safety belt incorporates a safety belt reminder light in the instrument cluster to remind the driver
if the safety belt is not fastened when the ignition is
turned ON.
THREE-POINT PRETENSIONER
FRONT SEAT BELT (W/EUROPE
ONLY)
The pretensioner front seat belt is optional. It contains a
electrically-controlled pyrotechnical retractor, which reduces seat belt slack when it is activated in a head-on or
angled front collision. The pretensioner front seat belt
must be replaced after an accident that causes its activation.
THREE-POINT WLR FRONT SEAT
BELT
The three-point web locking retractor (WLR) seat belt
will limit the movement of the driver and offer better
protection in an accident.
THREE-POINT ELR FRONT SEAT
BELT
The three-point emergency locking retractor (ELR) front
seat belt is always unlocked, allowing the passenger
freedom of movement, except in emergencies (rapid deceleration, rapid acceleration, or hard cornering maneuvers).
THREE-POINT ELR REAR
OUTBOARD SEAT BELT
The rear outboard seating positions use the three-point
emergency locking retractor (ELR) seat belts. The
three-point emergency locking retractor (ELR) seat belt
is always unlocked, allowing the passenger freedom of
movement, except in emergencies (rapid deceleration,
rapid acceleration, or hard cornering maneuvers).
TWO-POINT LAP REAR CENTER
SEAT BELT
The two-point lap rear center seat belt is a single continuous length of webbing. The webbing is routed from the
anchor through a latch plate and into a single retractor.
OPERATIONAL AND FUNCTIONAL
CHECKS
Caution:
D Keep sharp objects and potentially damaging objects away from the seat belts.
D Avoid bending or damaging any portion of the
buckle or the latch plate.
D Do not bleach or dye the belt webbing. Use only
mild soap and water in order to clean the belts.
D When installing the seat belt anchor bolts and
the screws, start the bolts and the screws by
hand in order to prevent crossthreading.
D Do not attempt any repairs on the retractor mechanisms or the covers. Replace any defective assemblies with new assemblies.
D Replace any belts that are cut or damaged in any
way.
1. Inspect all seat belt anchor bolts and the screws in order to verify that they are secure.
2. Inspect the seat belt buckle. The buckle must lock
and unlock easily.
3. After inserting the latch into the buckle, tug sharply on
the belt. The buckle must remain locked.
4. Fully extend the shoulder belt portion to make sure
that there is no twisting or tears in the belt.
5. Let the shoulder belt retract fully. The belt should retract easily.

or the external circuits, the SIR warning lamp in the instrument cluster turns ON.
The clock spring should never be disassembled.
The clock spring must be replaced if the airbags have
been deployed.
As a system check, the SIR warning lamp also turns ON
when the ignition is first switched to the ON position.
Correct Functioning
The system is working properly if:
D The SIR warning lamp turns OFF after approximately
four seconds.
Faulty Functioning
The system is not working properly, meaning one of the

WIRING HARNESS/CONNECTORS
The connector for the sensing and diagnostic module
(SDM) has a built-in shorting bar that will turn ON the
warning lamp if there is a poor connection at the SDM.
As an anti-deployment mechanism, additional shorting
bars are in the
D Connector for the clock spring at the lower steering
column.
D Passenger airbag module connector.
D110B009A
CLOCK SPRING
D SDM connector.
When these connectors are separated, the shorting
bars will short circuit any current which is applied, preventing the current from reaching the airbag modules.
The clock spring:
D Is on the steering column.
D Contains a coil that is the electrical contact between
the steering column wiring harness and the driver
side airbag module.
D Is part of the circuit for the horn.
Notice: Turning the steering wheel more than three and
one-quarter turns may damage the clock spring.
Turning the steering wheel:
D In one direction tightens the coil.
D In the opposite direction loosens the coil.
D More than three and one-quarter turns may damage
the clock spring.
Caution: Disassembling the clock spring can cause
injury and vehicle damage.
SIR SYSTEM
The supplemental inflatable restraints (SIR) system is a
safety device used in conjunction with the seat belts.
The airbag does not replace the function of the seat belt.
The driver and the passengers must always fasten their
seat belts and adjust them for a proper fit.
The SIR is designed to protect the driver and the front
seat passenger in the event of a significant frontal impact to the vehicle. The airbags deploy if the force is applied from a direction within 30 degrees of the vehicle’s
centerline and above 25 km/h (15 mph) speed.
The SIR consists of a
D Driver airbag module.
D Passenger airbag module.

DIAGNOSTIC INFORMATION AND PROCEDURES
A scan tool connected to the data link connector (DLC):
D Reveals the fault codes.
D Receives serial data transmission through the terminal J (13) of the DLC.
D Receives ground through the terminal A (4) of the
DLC.
CLEARING FAULT CODES
When the sensing and diagnostic module (SDM) receives the CODE ERASE command from the scan tool,
the SDM:
D Clears the entire fault memory.
D Turns OFF the warning lamp.
D Resets for fault detection.
D110B009A
External Fault
Service personnel can reset the SDM and turn OFF the
warning lamp if the fault is an external fault.
BULB CHECK
Internal Fault
As soon as the operating voltage is applied to the sensing and diagnostic module (SDM) ignition input, the
SDM activates the warning lamp for a bulb check.
The SDM turns the lamp ON for 4 seconds, and then the
SDM turns the lamp OFF.
During the bulb check, the SDM is not ready to detect a
crash or deploy the supplemental inflatable restraints.
An internal fault of the SDM or a CRASH RECORDED
fault code cannot be reset.
In the case of an internal fault of the SDM or a CRASH
RECORDED fault code, the SDM must be replaced.
FAULT INDICATION
MICROPROCESSOR –
INDEPENDENT LAMP ACTIVATION
The sensing and diagnostic module records the system’s faults in two categories:
D Current faults and the fault code appears “Axx” on the
scan tool display.
D Historic faults, which are those that were detected in
the past, but are no longer active. And the fault code
appears “Sxx” on the scan tool display.
The warning lamp:
Voltage-Low Fault
The SDM will turn OFF the VOLTAGE LOW fault as
soon as the voltage recovers.
If the sensing and diagnostic module (SDM) electrical
connector is not properly attached, the SDM cannot
function and cannot control the warning lamp.
If this fault is present, the warning lamp will operate independently from the SDM through the use of shorting
bars that are built into the SDM connector.
D Indicates a fault as soon as it occurs.
D Stays ON, even if a fault is no longer active.

SYSTEM CHECK
D1AB301B
Caution: Use only the scan tool to check the airbag
modules and the sensing and diagnostic module
(SDM). Never measure the resistance of an airbag
module with an ohmmeter. An ohmmeter’s battery
can deploy the airbag and cause injury.
Caution: Do not attempt to repair the supplemental
inflatable restraints (SIR) wiring harness. An SIR repair can create a high-resistance connection which
can keep the airbags from deploying when needed,
resulting in injury.
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is disconnected. Unintentional deployment of the airbags
can cause injury.
Circuit Description
When the ignition switch is turned ON, the SDM is able
to send serial data from the terminal 9 of the SDM to the
terminal J (13) of the assembly line diagnostic link.

DIAGNOSTIC TROUBLE CODE (DTC) 01
DRIVER FIRING CIRCUIT, RESISTANCE TOO HIGH
Open Circuit
Circuit Description
When the ignition switch is turned ON, the sensing and
diagnostic module (SDM) will perform tests to diagnose
any malfunctions within itself.
After passing these tests, the SDM will check the driver
airbag module firing circuit. The SDM allows a very
small amount of current to flow through the driver airbag
module firing circuit. The SDM monitors the circuit resistance during this check.
DTC 01 Will Set When
D The combined resistance of the driver airbag module,
the harness wiring, and the connector contacts is
above a specified value, as with an open circuit.
Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is disconnected. Unintentional deployment of the airbags
can cause injury.
Caution: Never measure the resistance of an airbag
module with an ohmmeter. An ohmmeter’s battery
can deploy the airbag and cause injury.
Caution: Do not attempt to repair the supplemental
inflatable restraints (SIR) wiring harness. A repair
can create a high-resistance connection which can
keep the airbags from deploying when needed, resulting in injury.

DRIVER FIRING CIRCUIT, RESISTANCE TOO LOW
Short Circuit
Circuit Description
When the ignition switch is turned ON, the sensing and
diagnostic module (SDM) will perform tests to diagnose
any malfunctions within itself.
After passing these tests, the SDM will check the driver
airbag module firing circuit. The SDM allows a very
small amount of current to flow through the airbag
module firing circuit. The SDM monitors the circuit resistance during this check.
DTC 02 Will Set When
D The combined resistance of the driver airbag module,
the harness wiring, and the connector contacts is below a specified value, as with a short circuit between
the wires to the driver airbag module.
Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is disconnected. Unintentional deployment of the airbags
can cause injury.
Caution: Never measure the resistance of an airbag
module with an ohmmeter. An ohmmeter’s battery
can deploy the airbag and cause injury.

DIAGNOSTIC TROUBLE CODE (DTC) 05
PASSENGER FIRING CIRCUIT, RESISTANCE TOO HIGH
Open Circuit
Circuit Description
When the ignition switch is turned ON, the sensing and
diagnostic module (SDM) will perform tests to diagnose
any malfunctions within itself.
After passing these tests, the SDM will check the
passenger airbag firing circuit. The SDM allows a very
small amount of current to flow through the circuit. The
SDM monitors the circuit resistance during this check.
DTC 05 Will Set When
D The combined resistance of the passenger airbag
module, the harness wiring, and the connector contacts is above a specified value, as in an open circuit.
Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is disconnected. Unintentional deployment of the airbags
can cause injury.
Caution: Never measure the resistance of an airbag
module. If the anti-deployment shorting bar on the
module-side of the connector is not working properly, the meter’s battery can deploy the airbag and
cause injury.

DRIVER PRETENSIONER CIRCUIT, RESISTANCE TOO HIGH
Open Circuit
Circuit Description
When the ignition switch is turned ON, the sensing and
diagnostic module (SDM) will perform tests to diagnose
any malfunctions within itself.
After passing these tests, the SDM will check the
driver pretensioner circuit. The SDM allows a very small
amount of current to flow through the circuit. The SDM
monitors the circuit resistance during this check.
DTC 09 Will Set When
D The combined resistance of the driver pretensioner
module, the harness wiring, and the connector contacts is above a specified value, as in an open circuit.
Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is disconnected. Unintentional deployment of the airbags
can cause injury.
Caution: Never measure the resistance of an airbag
module. If the anti-deployment shorting bar on the
module-side of the connector is not working properly, the meter’s battery can deploy the airbag and
cause injury.

PASSENGER PRETENSIONER CIRCUIT, RESISTANCE TOO HIGH
Open Circuit
Circuit Description
When the ignition switch is turned ON, the sensing and
diagnostic module (SDM) will perform tests to diagnose
any malfunctions within itself.
After passing these tests, the SDM will check the
passenger pretensioner circuit. The SDM allows a very
small amount of current to flow through the circuit. The
SDM monitors the circuit resistance during this check.
DTC 13 Will Set When
D The combined resistance of the passenger pretensioner module, the harness wiring, and the connector
contacts is above a specified value, as in an open circuit.
Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is disconnected. Unintentional deployment of the airbags
can cause injury.
Caution: Never measure the resistance of an airbag
module. If the anti-deployment shorting bar on the
module-side of the connector is not working properly, the meter’s battery can deploy the airbag and
cause injury.

Circuit Description
When the ignition switch is turned ON, the sensing and
diagnostic module (SDM) will perform tests to diagnose
any malfunctions within itself.
After passing these tests, the SDM will check the driver
airbag and the driver pretensioner circuit. The SDM allows a very small amount of current to flow through the

Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is disconnected. Unintentional deployment of the airbags
can cause injury.
Caution: Never measure the resistance of an airbag
module. If the anti-deployment shorting bar on the
module-side of the connector is not working properly, the meter’s battery can deploy the airbag and
cause injury.

DIAGNOSTIC TROUBLE CODE (DTC) 21
CONNECTION BETWEEN PASSENGER FIRING CIRCUIT AND PASSENGER
PRETENSIONER CIRCUIT
Open Circuit
Circuit Description
When the ignition switch is turned ON, the sensing and
diagnostic module (SDM) will perform tests to diagnose
any malfunctions within itself.
After passing these tests, the SDM will check the
passenger airbag and the passenger circuit. The SDM
allows a very small amount of current to flow through the
circuit. The SDM monitors the circuit resistance during
this check.
DTC 21 Will Set When
D Connection between the passenger firing circuit and
the passenger pretensioner circuit or SDM internal
connection problem may exist.
Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is disconnected. Unintentional deployment of the airbags
can cause injury.
Caution: Never measure the resistance of an airbag
module. If the anti-deployment shorting bar on the
module-side of the connector is not working properly, the meter’s battery can deploy the airbag and
cause injury.

DIAGNOSTIC TROUBLE CODE (DTC) 25
WARNING LAMP FAILURE
Circuit Description
When the ignition switch is turned ON, the sensing and
diagnostic module (SDM) will perform tests to diagnose
any malfunctions within itself.
After passing these tests, the SDM will check the warning lamp circuit. The SDM constantly measures the voltage at the warning lamp output in order to determine if
the lamp is ON or OFF at the correct time.
DTC 25 Will Set When
D The lamp is ON when it should be OFF.
D The lamp is OFF when it should be ON.
Diagnostic Aids
When the warning lamp operates correctly, the warning
lamp turns ON for approximately four seconds after the
ignition is first switched ON, and then The warning lamp
turns OFF.
When the warning lamp operates incorrectly, the warning lamp continues to blink four times per second,
demonstrating that the SDM is faulty and must be replaced.
Test Description
Caution: Before testing, disconnect the negative
battery cable. Wait 1 minute for the SDM capacitor
to discharge. The capacitor supplies reserve power
to deploy the airbags, even if the battery is disconnected. Unintentional deployment of the airbags
can cause injury.
Caution: If the short is in the supplemental inflatable
restraints (SIR) wiring harness, do not attempt to repair it. The repair might create a high-resistance
connection which can keep the airbags from deploying when needed, resulting in injury. Replace the
SIR wiring harness if it is damaged.

DEPLOYED AIRBAG MODULE
DISPOSAL PROCEDURE
Caution: After an airbag module has been
deployed, the surface of the airbag may contain a
powdery residue. The powder lubricates the airbag
as it inflates. The dust that is produced as a byproduct of the deployment is unlikely to be harmful,
but use the gloves and the safety glasses in order to
prevent any possible irritation of the skin and the
eyes.
Caution: After deployment, the metal surfaces of
the airbag module will be hot. In order to avoid the
risk of an injury or a fire, do not place the deployed
airbag modules near any flammable objects, and allow the airbag modules to cool for 30 minutes before handling them.
Deploy an airbag before disposing of it. This includes
those in a whole vehicle being scrapped.
