General Precautions

Please read the following precautions carefully before performing the airbag system service. Observe the instructions described in this manual, or the airbags could accidentally deploy and cause damage or injuries.

• Except when performing electrical inspections, always turn the ignition switch OFF and disconnect the negative cable from the battery, and wait at least three minutes before beginning work.

The contents in the memory is not erased even if the ignition switch is turned OFF or the battery cables are disconnectedfrom the battery.

• Use the replacement parts which are manufactured to the same standards as the original parts and quality.

Do not install used SRS parts from another vehicle.

Use only new parts when making SRS repairs.

• Carefully inspect any SRS part before you install it.

Do not install any part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation.

• Before removing any of the SRS parts (including the disconnection of the connectors), always disconnect the SRS connector.

Airbag Handling and Storage

Do not disassemble the airbags; it has no serviceable parts. Once an airbag has been deployed, it cannot be repaired or reused.

For temporary storage of the air bag during service, please observe the following precautions.

• Store the removed airbag with the pad surface up.

• Keep free from any oil, grease, detergent, or water to prevent damage to the airbag assembly.

https://www.kiatechinfo.com/viewer/toc_print.asp?vehicletype=Passenger&mfrcode=KM&area=KM… 1/227


• Store the removed airbag on secure, flat surface away from any high heat source (exceeding 85°C/185°F).

• Never perform electrical inspections to the airbags, such as measuring resistance.

• Do not position yourself in front of the airbag assembly during removal, inspection, or replacement.

• Refer to the scrapping procedures for disposal of the damaged airbag.

• Be careful not to bump or impact the SRS unit or the side impact sensors whenever the ignition switch is ON, wait at least three minutes after the ignition switch is turned OFF before begin work.

• During installation or replacement, be careful not to bump (by impact wrench, hammer, etc.) the area around the

SRS unit and the side impact sensor. The airbags could accidentally deploy and cause damage or injury.

• After a collision in which the airbags were deployed, replace the front airbags and the SRS unit. After a collision in which the side airbag was deployed, replace the side airbag, the front impact sensor and side impact sensor on the side where the side airbag deployed and the SRS unit. After a collision in which the airbags or the side air bags did not deploy, inspect for any damage or any deformation on the SRS unit and the side impact sensors. If there is any damage, replace the SRS unit, the front impact sensor and/or the side impact sensors.

• Do not disassemble the SRS unit, the front impact sensor or the side impact sensors

• Turn the ignition switch OFF, disconnect the battery negative cable and wait at least three minutes before beginning installation or replacement of the SRS unit.

• Be sure the SRS unit, the front impact sensor and side impact sensors are installed securely with the mounting bolts.

• Do not spill water or oil on the SRS unit,or the front impact sensor or the side impact sensors and keep them away from dust.

• Store the SRS unit, the front impact sensor and the side impact sensors in a cool (less than 104°F/40°C) and dry

(less than 80% relative humidity, no moisture) area.

Wiring Precautions

SRS wiring can be identified by special yellow outer covering (except the SRS circuits under the front seats).

Observe the instructions described in this section.

• Never attempt to modify, splice, or repair SRS wiring.

If there is an open or damage in SRS wiring, replace the harness.



• Be sure to install the harness wires so that they are not pinched, or interfere with other parts.

• Make sure all SRS ground locations are clean, and grounds are securely fastened for optimum metaltometal contact. Poor grounding can cause intermittent problems that are difficult to diagnose.

Precautions for Electrical Inspections

• When using electrical test equipment, insert the probe of the tester into the wire side of the connector.

Do not insert the probe of the tester into the terminal side of the connector, and do not tamper with the connector.

• Use a ushaped probe. Do not insert the probe forcibly.

• Use specificed service connectors for troubleshooting.

Using improper tools could cause an error in inspection due to poor metal contact.

WARNING LAMP ACTIVATION

1. Active fault or historical fault counter is greater or equal to 10

2. Normal or historical fault counter is less than 10

3. Loss of battery supply to the SRSCM : warning lamp turned on continuously.

4. Loss of internal operating voltage : warning lamp turned on continuously.

5. Loss of SRSCM operation : warning lamp turned on continuously.

6. SRSCM not connected : warning lamp turned on continuously through the shorting bar.

7. Reset by the Watchdog Trigger failure : warning lamp flashed or turned on continuously.

TELLTALE LAMP ACTIVATION

DESCRIPTION



The Telltale Lamp indicates the Passenger Airbag(PAB) enable disable status based on occupant status of passenger seat. If the passenger seat is occupied with child (or child seat), the Passenger Airbag is disabled and the Telltale

Lamp is turned ON to inform the driver that the PAB is disabled.

As soon as operating voltage is applied to the SRSCM ignition input, the SRSCM activates telltale lamp prove out.

OCS will send an indeterminate status to the SRSCM as a default setting for passenger airbag deployment during the prove out period. After crash if OCS gets reset and sends the indeterminate status, the telltale lamp will be ON as long as the occupant status is in the indeterminate status. Occupant status information and telltale ststus are as below table.

Restraint > General Information > General Information

Description

The supplemental restraint system (SRS) is designed to supplement the seat belt to help reduce the risk or severity of injury to the driver and passenger by activating and deploying the driver, passenger, side airbag and belt pretensioner in certain frontal or side collisions.

The SRS (Airbag) consists of : a driver side airbag module located in the center of the steering wheel, which contains the folded cushion and an inflator unit ; a passenger side airbag module located in the passenger side crash pad containsthe folded cushion assembled with inflator unit ; side airbag modules located in the driver and passenger seat contain the folded cushion and an inflator unit ; curtain airbag modules located inside of the headliner which contains folded cushions and inflator units. The Passenger Occupant classification System (OCS) utilizes bladder placed between the passenger seat cushion and suspension to measure the occupant’s loading force on the vehicle seat. Seat

Track Position Sensor (STPS) located in driver and passenger seat interfaces with SRSCM and will help in determining whether to suppress either stage of a multistage airbag system. SRSCM is located under the center console. The impact sensing function of the SRSCM is carried out by electronic accelerometer that continuously measure the vehicle's acceleration and delivers a corresponding signal through amplifying and filtering circuitry to the microprocessor.

SRSCM (SRS Control Module)



SRSCM will detect front impact with front impact sensor, and side impact with side impact sensor, and determine airbag module deployment.

1. DC/DC converter: DC/DC converter in power supply unit includes up/down transformer converter, and provide ignition voltage for 2 front airbag ignition circuits and the internal operation voltage of the SRSCM. If the internal operation voltage is below critical value setting, it will perform resetting.

2. Safety sensor: Safety sensor is located in airbag ignition circuit. Safety sensor will operate airbag circuit at any deployment condition and release airbag circuit safely at normal driving condition. Safety sensor is a double contact electromechanical switch that will close detecting deceleration above certain criteria.

3. Back up power supply: SRSCM has separate back up power supply, that will supply deployment energy instantly in low voltage condition or upon power failure by front crash.

4. Self diagnosis: SRSCM will constantly monitor current SRS operation status and detect system failure while vehicle power supply is on, system failure may be checked with trouble codes using scan tool. (HiScan)

5. Airbag warning lamp on: Upon detecting error, the module will transmit signal to SRSCM indicator lamp located at cluster. MIL lamp will indicate driver SRS error. Upon ignition key on, SRS lamp will turn on for about six seconds.

6. Trouble code registration: Upon error occurrence in system, SRSCM will store DTC corresponding to the error. DTC can be cleared only by HiScan. However, if an internal fault code is logged or if a crash is recorded thefault clearing should not happen.

7. Self diagnostic connector: Data stored in SRSCM memory will be output to HiScan or other external output devices through connector located below driver side crash pad.

8. Once airbag is deployed, SRSCM should not be used again but replaced.

9. SRSCM will determine whether passenger put on seat belt by the signal from builtin switch in seat belt buckle, and deploy front seat airbag at each set crash speed.

10. Side airbag deployment will be determined by SRSCM that will detect satellite sensor impact signal upon side crash, irrespective to seat belt condition.

Restraint > Supplemental Restraint System Control Module (SRSCM) > SRS Control

Module (SRSCM) > Description and Operation

DESCRIPTION

The primary purpose of the advanced SRSCM (Supplemental Restraints System Control Module) is to discriminate between an event that warrants restraint system deployment and an event that does not. The advanced SRSCM must decide if and when to deploy the restraint system pretensioners and airbags. After determining that pretensioners and/or airbag deployment is required, the advanced SRSCM must supply sufficient power to the pretensioners and airbag igniters to initiate deployment. The advanced SRSCM determines that an impact may require deployment of the pretensioners and airbags from data obtained from buckle switches, seat track position sensors, occupant classification system, front impact sensors and side impact sensors in conjunction with a safing function.

The advanced SRSCM will not be ready to detect a crash or to activate the restraint system devices until the signals in the advanced SRSCM circuitry stabilize. It is possible that the advanced SRSCM could activate the safety restraint devices in approximately 2 seconds but is guaranteed to fully function after proveout is completed. The advanced

SRSCM must perform a diagnostic routine and light a system readiness indicator at keyon. The system must perform a continuous diagnostic routine and provide fault annunciation through a warning lamp indicator in the event of fault detection. A serial diagnostic communication interface will be used to facilitate servicing of the advanced restraint control system.

Restraint > Supplemental Restraint System Control Module (SRSCM) > Front Impact

Sensor (FIS) > Description and Operation

DESCRIPTION

The release system for the front airbag consists of a SRSCM installed in the middle of the vehicle and two front impact sensors (FIS) which are located in front of the vehicle. Only the SRSCM is capable of releasing the airbags or the seat belt pretensioner system in the vehicle. In the dialog between the SRSCM and the front impact sensor it is the SRSCM which takes the release decision.



The SRSCM is supported in connection with the front airbag function by the two front impact sensors, which act as intelligent acceleration sensors and as such back up the central airbag controller. Both the front impact sensors continuously report the current system status of the vehicle to the SRSCM.

If one of the two front impact sensor reports an acceleration level, the SRSCM must verify the acceleration signal internally by means of a suitable plausibility check. The SRSCM does not release the appropriate airbag unless the result of this verification is positive.

Restraint > Supplemental Restraint System Control Module (SRSCM) > Seat Track

Position Sensor (STPS) > Description and Operation

DESCRIPTION

The STPS operated via a noncontacting magnetic proximity sensing device combined with a simple electronic circuit resulting in the ability of producing two separate and distinct logic level signals.

The STPS output signal is altered by the proximity of a separate ferromagnetic shunt, which is linked via the seat track. The logic signal produced is the result of the proximity device being activated (no shunt present) or deactivated

(shunt present).

When the seat is in the forward position zone of the track, the sensor gives a low current (prohibit) signal. When the seat is in the rear positon zone of the track, it gives a high current (enable) signal.

DESCRIPTION

The buckle status shall modify the SRSCM deployment. If the Buckle Status is Unbuckled, the corresponding pretensioner will be deactivated.

Restraint > Supplemental Restraint System Control Module (SRSCM) > Occupant

Classification Sensor (OCS) > Description and Operation

DESCRIPTION

The system is intended to classify the occupancy status of the front passenger seat in a motor vehicle based upon the measured force on the bottom seat cushion.

The system also communicates to the SRSCM whether to allow or inhibit the deployment of the passenger airbags and/or pretensioner based upon this status.

The System also measured dynamic responses of the occupant. This information is used to idenitify when a child seat is cinched down tightly with the seat belt, and to also determine if the seat is unoccupied.

However, the dynamic measurements are not intended, nor capable of monitoring the seating position of the occupant, nor can they determine the proximity of the occupant to the inflator modules.

The system should not be confused with an occupant position recognition system, or any other occupant proximity sensor.

The Passenger Occupant Detecting System (PODS) utilizes bladder placed between the passenger seat cushion and suspension to measure the occupant's loading force on the vehicle seat. The bladder is connected to pressure sensor and ultimately to an electronic control unit (ECU), both of which are mounted under the seat pan. The quantitative force determined by the system is compared to a given threshold for determination of passenger airbag suppression.

AIRBAG DISPOSAL

Special Tool Required

Before scrapping any airbags or side airbags (including those in a whole vehicle to be scrapped), the airbags or side airbags must be deployed. If the vehicle is still within the warranty period, before deploying the airbags or side airbags, the Technical Manager must give approval and/or special instruction. Only after the airbags or side airbags have been deployed (as the result of vehicle collision, for example), can they be scrapped.

If the airbags or side airbags appear intact (not deployed), treat them with extreme caution. Follow this procedure.

Deploying Airbags In the vehicle

If a SRS equipped vehicle is to be entirely scrapped, its airbags or side airbags should be deployed while still in the vehicle. The airbags or side airbags should not be considered as salvageable parts and should never be installed in another vehicle.

1. Turn the ignition switch OFF, and disconnect the battery negative cable and wait at least three minutes.

2. Confirm that each airbag or side airbag are securely mounted.

3. Confirm that the special tool is functioning properly by following the check procedure.

Driver's Airbag AND BPT :

1. Remove the driver's airbag and the install the SST(0957A38500).



2. Install the driver's airbag on the steering wheel.

Front Passenger's Airbag :

1. Remove the glove box, then disconnect the 4P connector between the front passenger's airbag and SRS main harness.

2. Install the SST(0957A38100).

Buckle Pretensioner

1. Disconnect the 6p connect between the buckle pretensioner and buckle pretensioner wire Harness.

2. Install the SST(0957A 2E210)

Side Airbag, CURTAIN AIRBAG:

1. Disconnect the 2P connector between the side airbag and side wire harness.

2. Install the SST (0957A38100 : SAB, 0957A38500 : CAB).

3. Place the deployment tool at least thirty feet (10 meters) away from the airbag.

4. Connect a 12 volt battery to the tool.

5. Push the tool's deployment switch. The airbag should deploy. Repeat for 2nd circuit if deploying DAB or PAB.

(deployment is both highly audible and visible: a loud noise and rapid inflation of the bag, followed by slow deflection)

6. Dispose of the complete airbag. No part of it can be reused. Place it in a sturdy plastic bag and seal it securely.

Deploying the Airbag Out of the vehicle

If an intact airbag has been removed from a scrapped vehicle, or has been found defective or damage during transit, storage or service, it should be deployed as follows :

1. Confirm that the special tool is functioning properly by following the check procedure on this page.

2. Position the airbag face up, outdoors on flat ground at least thirty feet (10meters) from any obstacles or people.

Disposal of Damaged Airbag

1. If installed in a vehicle, follow the removal procedure of driver's airbag, front passenger's and side airbag.

2. In all cases, make a short circuit by twisting together the two airbag inflator wires.

3. Package the airbag in exactly the same packing that the new replacement part come in.

Restraint > Airbag Module > Driver Airbag (DAB) Module and Clock Spring > Description and Operation

DESCRIPTION

Driver Airbag (DAB) is installed in steering wheel and electrically connected to SRSCM via clockspring. It protects the driver from danger with deploying a bag when frontal crash occurs. The SRSCM determines deployment of Driver Airbag

(DAB) by using the Front Impact Sensor (FIS) signal. The driver airbag is two stage devices.

If the crash algorithm determines that only the first stage is to be activated, the second stage will be automatically https://www.kiatechinfo.com/viewer/toc_print.asp?vehicletype=Passenger&mfrcode=KM&area=KM… 26/227

7/6/12 https://www.kiatechinfo.com/viewer/toc_print.asp?vehicletype=Passenger&mfrcode=KM&area=KM… disposed of after a programmable time in milliseconds (120ms) has elapsed since the first stage deployment. The driver firing loops (2 total) are backed up (BPS) for 150ms if the battery connection is lost in a crash.

Never attempt to measure the circuit resistance of the airbag module (squib) even if you are using the specified tester. If the circuit resistance is measured with a tester, accidental airbag deployment will result in serious personal injury.
