Both the driver and passenger airbags are certified to new federal regulations, which allows them to deploy with less force than prior airbags. The primary occupant restraints in this vehicle are the seat belts, which require active use by the vehicle occupants. The front airbag system is a supplemental passive restraint that was designed and is intended to enhance the protection page INSTALLATION...12 OCCUPANT RESTRAINT CONTROLLER DESCRIPTION...12 OPERATION...12 REMOVAL...13 INSTALLATION...13 PASSENGER AIRBAG DESCRIPTION...13 OPERATION...14 REMOVAL...14 INSTALLATION...15 PASSENGER AIRBAG COVER REMOVAL...15 INSTALLATION...15 REAR CENTER SEAT BELT & RETRACTOR REMOVAL...16 INSTALLATION...16 REAR SEAT BELT & RETRACTOR REMOVAL...16 INSTALLATION...16 REAR SEAT BELT BUCKLE REMOVAL...16 SEAT AIRBAG DESCRIPTION...16 OPERATION...17 REMOVAL...17 INSTALLATION...18 SIDE IMPACT AIRBAG CONTROL MODULE DESCRIPTION...19 OPERATION...19 REMOVAL...19 INSTALLATION...20 for the front seat occupants of the vehicle when used in conjunction with the seat belts. The driver airbag includes an inflatable airbag and an inflator unit behind a trim cover in the hub area of the steering wheel. The passenger airbag includes an inflatable airbag and an inflator unit behind an airbag door in the instrument panel above the glove box. The dual front airbag system consists of the following components: Occupant Restraint Controller (ORC) Airbag indicator lamp. Clock Spring Driver and passenger airbags (including the airbag inflators).

Refer to the proper Body Diagnostic Procedures manual to test or diagnose a problem with any component of the front airbag system. SIDE IMPACT AIRBAG SYSTEM The Side Impact Airbag System utilizes two airbags, one mounted to each front seat back frame. This system is designed to enhance protection of occupants in the event of a side impact collision. BELT TENSIONER SYSTEM The seat belt system incorporates Tensioner Modules. They are integral to the seat belt retractors (Fig. 2) and cannot be serviced. If found defective they must be replaced. OPERATION FRONT AIRBAG SYSTEM The front airbag system electrical circuits are continuously monitored by a microprocessor and software contained within the Occupant Restraint Controller (ORC). The ORC also contains impact sensing elements, which are monitored by the ORC to determine when an impact occurs that is severe enough to require front airbag system protection. When a frontal impact is severe enough, the ORC initiates the inflator units of both front airbags to deploy. Fig. 2 SEAT BELT TENSIONER LOCATION - TYPICAL 1 - SEAT BELT TENSIONER An airbag indicator lamp in the instrument cluster lights for six to eight seconds as a bulb test each time the ignition switch is turned to the ON position. Following the bulb test, the airbag indicator lamp is turned ON or OFF by the ORC to indicate the status of the airbag system. If the airbag indicator lamp comes ON at any time other than during the bulb test, it indicates that there is a problem in the airbag system. Such a problem may cause the airbags not to deploy when required, or to deploy when not required. During a frontal vehicle impact, the knee blockers work in conjunction with properly adjusted seat belts to restrain the driver and front seat passenger in the proper position for an airbag deployment. The knee blockers also work to absorb and distribute the crash energy from the driver and front seat passenger to the structure of the instrument panel. The driver side knee blocker is integral to the lower instrument panel bezel. The passenger side knee blocker is integral to the glove box door. SIDE IMPACT AIRBAG SYSTEM The Side Impact Airbag Control Modules (SIACM) control the seat back mounted airbags (one left and one right). If a SIACM determines the impact is severe enough, the appropriate airbag will inflate, tearing open the front seat back trim cover protecting the occupants. Once a seat back mounted airbag has been deployed, the entire seat back as well as any damaged parts must be replaced.

6 PT RESTRAINTS 8O - 3 RESTRAINTS (Continued) BELT TENSIONER SYSTEM At the onset of an impact event, each tensioner uses a pyrotechnic device which is triggered simultaneously with the airbags to rapidly retract the seat belts. With the slack removed, the occupant s forward motion in an impact will be reduced as will the likelihood of contacting interior components. WARNING: WHEN THE FRONT AIRBAG IS DEPLOYED, THE TENSIONER WILL HAVE DEPLOYED ALSO, AND MUST BE REPLACED. The ORC monitors the seat belt tensioner circuit and reports active and stored Diagnostic Trouble Codes (DTC s) if any problem is found. Once a vehicle has been in an accident, the tensioner will have a Gravel/Grinding sound to it after the tensioner has been put into use. This must be replaced along with any deployed airbags and broken or damaged parts. WARNING FRONT AIRBAG SYSTEM WARNING: THIS SYSTEM CONTAINS A SENSITIVE, COMPLEX ELECTRONIC UNIT. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE REMOTE CABLE BEFORE BEGINNING AIRBAG SYSTEM COMPONENT REMOVAL OR INSTALLATION PRO- CEDURES. THIS WILL DISABLE THE AIRBAG SYS- TEM. FAILURE TO DISCONNECT THE BATTERY COULD RESULT IN ACCIDENTAL AIRBAG DEPLOY- MENT AND POSSIBLE PERSONAL INJURY. ALLOW SYSTEM CAPACITOR TO DISCHARGE FOR TWO MINUTES BEFORE REMOVING AIRBAG COM- PONENTS. DO NOT PLACE AN INTACT UNDEPLOYED AIRBAG FACE DOWN ON A SOLID SURFACE, THE AIRBAG WILL PROPEL INTO THE AIR IF ACCIDENTALLY DEPLOYED AND COULD RESULT IN PERSONAL INJURY. WHEN CARRYING OR HANDLING AN UNDEPLOYED AIRBAG, THE TRIM SIDE OF THE AIRBAG SHOULD BE POINTING TOWARD THE BODY TO MINIMIZE POSSIBILITY OF INJURY IF ACCIDENTAL DEPLOYMENT OCCURS. REPLACE AIRBAG SYSTEM COMPONENTS WITH MOPAR REPLACEMENT PARTS ONLY. SUBSTI- TUTE PARTS MAY APPEAR INTERCHANGEABLE, BUT INTERNAL DIFFERENCES MAY RESULT IN INFERIOR OCCUPANT PROTECTION. WEAR SAFETY GLASSES, RUBBER GLOVES, AND LONG SLEEVED CLOTHING WHEN CLEANING POWDER RESIDUE FROM THE VEHICLE AFTER AN AIRBAG DEPLOYMENT. SODIUM HYDROXIDE POW- DER RESIDUE EMITTED FROM A DEPLOYED AIR- BAG CAN CAUSE SKIN IRRITATION. FLUSH AFFECTED AREA WITH COOL WATER IF IRRITA- TION IS EXPERIENCED. IF NASAL OR THROAT IRRITATION IS EXPERIENCED, EXIT THE VEHICLE FOR FRESH AIR UNTIL THE IRRITATION CEASES. IF IRRITATION CONTINUES, SEE A PHYSICIAN. DO NOT USE A REPLACEMENT AIRBAG THAT IS NOT IN THE ORIGINAL PACKAGING, IMPROPER DEPLOYMENT AND PERSONAL INJURY CAN RESULT. THE FACTORY INSTALLED FASTENERS, SCREWS AND BOLTS USED TO FASTEN AIRBAG COMPO- NENTS HAVE A SPECIAL COATING AND ARE SPE- CIFICALLY DESIGNED FOR THE AIRBAG SYSTEM. DO NOT USE SUBSTITUTE FASTENERS, USE ONLY ORIGINAL EQUIPMENT FASTENERS LISTED IN THE PARTS CATALOG WHEN FASTENER REPLACE- MENT IS REQUIRED. AIRBAGS SHOULD BE STORED IN A COOL, DRY PLACE, AWAY FROM EXCESSIVE HEAT AND STATIC ELECTRICAL ACTIVITY WITH THE FABRIC AIRBAG FACING UP. IF NOT, A PREMATURE DEPLOYMENT CAN RESULT. NOTE: Please refer to the Hazardous Substance Control System for Proper Disposal. Dispose of deployed air bags in a manner consistent with state, provincial, local, and federal regulations.

DIAGNOSIS AND TESTING - AIRBAG SYSTEM (1) With the battery negative remote cable disconnected, connect the DRB III scan tool to the Data Link connector. (2) Turn the ignition key to the ON position. Exit vehicle with the scan tool. (3) After checking that no one is inside the vehicle, connect the battery negative remote terminal. (4) Read and record the ACTIVE Diagnostic Trouble Code (DTC) data. (5) Read and record any STORED DTC s. (6) Refer to the proper Body Diagnostic Procedures manual if any DTC s are found in Step 4 and Step 5. (7) If the airbag warning lamp either fails to light, or goes ON and stays ON, there is a system malfunction. To test the airbag warning lamp (bulb) operation in the cluster, refer to Electrical, Instrument Cluster, Diagnosis and Testing - Instrument Cluster. Refer to the proper Body Diagnostic Procedures manual for any other system problems. STANDARD PROCEDURE STANDARD PROCEDURE - HANDLING AIRBAGS DEPLOYED AIRBAG The vehicle interior may contain a very small amount of sodium hydroxide powder, a by-product of airbag deployment. Sodium hydroxide powder can irritate the skin, eyes, nose and throat. Wear safety glasses, rubber gloves, and long sleeved clothing when cleaning any of the powder residue from the vehicle. If you find that the cleanup is irritating your skin, run cool water over the affected area. Also, if you experience nasal or throat irritation, exit the vehicle for fresh air until the irritation ceases. If irritation continues, see a physician. UNDEPLOYED AIRBAG The airbags must be stored in its original special container until used for service. At no time should a source of electricity be permitted near the inflator on the back of an airbag module. When carrying or handling an undeployed airbag module, the trim side of the airbag should be pointing away from the body to minimize possibility of injury if accidental deployment occurs. Do not place undeployed airbag face down on a solid surface, the airbag will propel into the air if accidental deployment occurs.

11 8O - 8 RESTRAINTS PT DRIVER AIRBAG (Continued) The driver airbag protective trim cover is the most visible part of the driver airbag system (Fig. 6). The driver airbag is mounted directly to the steering wheel. Located under the airbag cover are the horn switch, the folded airbag cushion, and the airbag cushion supporting components (Fig. 7). The resistive membrane-type horn switch is secured within a pocket on the airbag cushion. The driver airbag cannot be repaired and must be replaced if deployed or in any way damaged. The driver airbag cover is available for service replacement if marred, scratched, or disfigured. The horn switch is not serviceable and if found faulty or defective, a complete driver airbag assembly will need to be installed. OPERATION The driver airbag includes a stamped metal housing to which the cushion and an inflator unit are attached and sealed. The conventional pyrotechnictype inflator assembly is mounted to studs on the back of the airbag housing. The inflator seals the hole in the airbag cushion so it can discharge the gas it produces directly into the cushion when supplied with the proper electrical signal. Following an airbag deployment, the airbag cushion quickly deflates by venting this gas towards the instrument panel through the porous fabric material used on the steering wheel side of the airbag cushion. The protective trim cover is fitted to the front of the airbag and forms a decorative cover in the center of the steering wheel. The inside of the trim cover has locking blocks molded into it that engage a lip on the airbag metal housing. Two stamped metal retainers then fit over the inflator mounting studs on the back of the airbag housing and are engaged in slots on the inside of the cover, securely locking the trim cover into place. The trim cover will split at predetermined breakout lines, then fold back out of the way along with the horn switch and tray unit upon airbag deployment. REMOVAL (1) Open hood. (2) Disconnect and isolate the battery negative cable. (3) Wait two minutes for the system reserve capacitor to discharge before servicing any airbag components. (4) Remove upper and lower steering column shrouds to gain access to clock spring wiring (Refer to 19 - STEERING/COLUMN/UPPER SHROUD - REMOVAL). (5) Using a pair of 90 internal snap ring pliers or equivalent, pry open the retaining clip (Fig. 8) on the back of the steering wheel to release the retaining pin (Fig. 9). Pull or press rearward on the driver airbag while doing this. The pin will release slightly. Fig. 8 DRIVER AIRBAG RETAINING PIN Fig. 9 FIRST DRIVER AIRBAG RETAINING PIN - REMOVAL (6) Using a pair of 90 internal snap ring pliers or equivalent, pry open the retaining clip (Fig. 10), and at the same time gently pry the pin away from the retaining clip, using a pocket screwdriver or equivalent, so it can slide through the middle of the clip. Use the screwdriver to push the pin through the clip. (7) When the driver airbag releases from the steering wheel, peel rearward and expose the underside of the airbag. Disconnect the two harness connectors, squib and horn feed (Fig. 11) and (Fig. 12). Use a small pocket screwdriver to separate horn connector. Insert into the bottom of the connector (airbag side) and pull handle of screwdriver up while pulling out on the clock spring side of the connector. (8) Remove airbag from vehicle.
