Passive Restraints

The passive restraints available for this vehicle include the following:

• Dual Front Airbags  - Driver and front passenger airbags are used in this vehicle. This airbag system is a passive, inflatable, Supplemental Restraint System (SRS) and vehicles with this equipment can be readily identified by the AIRBAG  logo molded into the driver airbag trim cover in the center of the steering wheel and also into the passenger airbag door area of the instrument panel above the glove box. Vehicles with the airbag system can also be identified by the airbag (also known as Supplemental Restraint System/SRS) indicator, which will illuminate in the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN or KOMBI) briefly as a bulb test each time the ignition switch is turned to the ON position. A pyrotechnic-type seat belt tensioner is also integral to each front seat belt retractor unit to work in conjunction with the dual front airbags.
• Seat Airbags  - Seat airbags (also known as thorax airbags) are optional equipment for this vehicle when it is also equipped with dual front airbags. This airbag system is a passive, inflatable, Supplemental Restraint System (SRS) and vehicles with this equipment can be readily identified by the AIRBAG  logo located on the trim molding on the outboard side of each front seat back. The vehicle may be equipped with a seat airbag for only the driver side, or for both the driver and passenger side front seats. Seat airbags are not available for the optional two-position front passenger bench seat.
• Side Curtain Airbags  - Side curtain airbags (also known as window airbags) are optional equipment for this vehicle when it is also equipped with dual front airbags. This airbag system is a passive, inflatable, Supplemental Restraint System (SRS) and vehicles with this equipment can be readily identified by the AIRBAG  logo located on the trim molding above each front door opening.

The supplemental restraint system includes the following major components, which are described in further detail elsewhere in this service information:

1. Airbag Indicator  - The airbag indicator is integral to the EMIC (also known as the Cab Compartment Node/CCN or KOMBI), which is located on the instrument panel in front of the driver.
2. Clockspring  - The clockspring also contains the integral Steering Angle Sensor (SAS) and the integral Steering Control Module (SCM) (also known as the steering column module/MRM), which is located near the top of the steering column, directly beneath the steering wheel.
3. Driver Airbag  - The driver airbag is located in the center of the steering wheel, beneath the driver airbag trim cover.
4. Driver Knee Blocker  - The structure of the lower instrument panel serves as a knee blocker for the driver.
5. Occupant Restraint Controller  - The Occupant Restraint Controller (ORC) (also known as the lowline or highline airbag control unit/ARCADE) is located on a mount on the floor panel transmission tunnel below the center of the instrument panel.
6. Passenger Airbag  - The passenger airbag is located in the instrument panel, behind the passenger airbag door and above the glove box on the passenger side of the vehicle.
7. Passenger Knee Blocker  - The structure of the glove box door and the lower instrument panel serve as a knee blocker for the front seat passenger.
8. Seat Belt Tensioner  - A seat belt tensioner is integral to each of the front seat belt retractor units. The outboard seating position retractors are located behind the trim on each lower B-pillar, while the center retractor on vehicles equipped with the optional two-position passenger front bench seat is concealed within the seat back.
9. Seat Airbags  - Vehicles with this optional equipment have a seat airbag unit located behind a trim cover on the outboard side of either the driver side front seat back or both the driver and passenger side front seat backs. A seat airbag is not available on vehicles equipped with the optional two-position front passenger bench seat.
10. Side Curtain Airbags  - Vehicles with this optional equipment have a side curtain airbag unit located on the inside of the roof side rail within a garnish molding that extends from the A-pillar to the B-pillar above each front door opening of the vehicle.
11. Side Impact Sensor  - Two side impact sensors are used on each side of vehicles equipped with the optional side curtain airbags or seat airbags. An acceleration-type impact sensor is located on each B-pillar, and a pressure-type sensor is located within each front door. Each of these impact sensors is concealed behind the interior trim components.

The ORC and the EMIC each contain a microprocessor and programming that allow them to communicate with each other using the Controller Area Network (CAN) data bus. This method of communication is used by the ORC for control of the airbag indicator in the EMIC. Refer to DESCRIPTION .

Hard wired circuitry connects the supplemental restraint system components to each other through the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system, and to the supplemental restraint system components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to SYSTEM WIRING DIAGRAMS The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
