Passive Restraints
The passive restraints available for this vehicle include the following:
- Active Head Restraints - Active Head Restraints (AHR) are standard equipment for both front seating positions in this vehicle. An AHR can be readily distinguished from a non-active head restraint by the two-piece construction used for an AHR. The forward-facing surface is padded and covered in a material coordinated with the other soft trim on the seat, while the rearward-facing surface is equipped with a molded plastic trim cover that matches the other hard trim on the seat.
- Dual Front Airbags - A multistage Driver AirBag (DAB) and front Passenger AirBag (PAB) are used in this vehicle. This airbag system consists of passive, inflatable, Supplemental Restraint System (SRS) components and vehicles with this equipment can be readily identified by the SRS - AIRBAG logo molded into the DAB trim cover in the center of the steering wheel and also into the PAB area of the instrument panel top cover above the glove box. Vehicles with the airbag system can also be identified by the airbag indicator, which will illuminate in the Instrument Panel Cluster (IPC) for about four to six seconds as a bulb test each time the status of the ignition switch transitions to ON. Pyrotechnic-type seat belt tensioners are also included for the driver and passenger front seat belts of all airbag equipped vehicles to work in conjunction with the dual front and side curtain airbags.
- Knee Airbag - The front airbag system also includes a Knee AirBag (KAB) that is located just beneath the steering column, behind the instrument panel steering column opening cover. This airbag is also a passive, inflatable, SRS component and vehicles with this equipment can be readily identified by the SRS - AIRBAG logo molded into the KAB trim cover on the instrument panel just beneath the steering column.
- Seat Airbags - Front seat-mounted Seat AirBags (SAB) are standard equipment in this vehicle. This airbag system consists of passive, inflatable, SRS components and vehicles with this equipment can be readily identified by a sewn tag with the SRS - AIRBAG logo located on the outboard side of the front seat back trim cover.
- Side Curtain Airbags - Side curtain airbags (also known as Side AirBag Inflatable Curtains/SABIC) are standard equipment for this vehicle when it is also equipped with dual front airbags. This airbag system consists of passive, inflatable, SRS components and vehicles with this equipment can be readily identified by a molded identification trim plug with the SRS - AIRBAG logo located near the headliner at the tops of each B and C-pillar trim.
The SRS includes the following major components, which are described in additional detail elsewhere in this service information:
- Active Head Restraints - On vehicles with this equipment, one AHR is located atop each front seat back unit.
- Airbag Indicator - The airbag indicator is integral to the IPC, which is located on the instrument panel in front of the driver.
- Clockspring - The clockspring is integral to the Steering Column Control Module (SCCM) located near the top of the steering column, directly beneath the steering wheel.
- Driver Airbag - The DAB is located in the center of the steering wheel, beneath the DAB trim cover.
- Driver Knee Blocker - The driver knee blocker is a static structural unit secured to the instrument panel, beneath the instrument panel steering column opening cover.
- Front Impact Sensor - Two front impact sensors are used on vehicles equipped with dual front airbags, one left side and one right side. One sensor is located on the back side of each vertical member of the radiator support.
- Knee Airbag - On vehicles manufactured for certain export markets equipped with the KAB feature, there is a KAB that is mounted behind the instrument panel steering column opening cover in place of the static driver knee blocker.
- Occupant Detection Sensor - An Occupant Detection Sensor (ODS) is located on the top of the seat cushion foam of the passenger side front seat in domestic market vehicles.
- Occupant Restraint Controller - The Occupant Restraint Controller (ORC) is located on a mount on the floor panel transmission tunnel behind the transmission gear selector, and is concealed below the center floor console.
- Passenger Airbag - The PAB is located in the instrument panel, beneath the instrument panel top cover, just forward and above the glove box on the passenger side of the vehicle.
- Passenger Knee Blocker - The passenger knee blocker is a static structural reinforcement that is integral to and concealed within the glove box door.
- Seat Airbag - A SAB unit is secured to each outboard front seat back frame, where it is concealed beneath the seat back trim cover and foam.
- Seat Belt Tensioner - A seat belt tensioner is integral to both front seat belt retractor units on vehicles equipped with dual front airbags. The seat belt retractor tensioner units are secured to the right and left lower inner B-pillar and are concealed behind the lower B-pillar trim.
- Side Curtain Airbag - A side curtain airbag (SABIC) is secured to each inside roof side rail above the headliner, which extends from the A-pillar to just beyond the C-pillar.
- Side Impact Sensor - Six side impact sensors are used on vehicles equipped with side curtain airbags, three on each side of the vehicle. One pressure-type sensor is located on each right and left front door hardware module carrier behind the front door trim panel. In addition, an acceleration-type sensor is located behind the B-pillar trim near the base of each B-pillar, and one acceleration-type sensor is located behind the quarter panel trim near the belt line of each C-pillar.
The ORC and the IPC each contain a microcontroller 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 IPC. Refer to COMMUNICATION, DESCRIPTION .
Hardwired circuitry connects the SRS components to each other through the electrical system of the vehicle. These hardwired 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 SRS 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 the appropriate wiring information. The wiring information includes wiring diagrams, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds. For proper wire repair, and connector repair procedures. Refer to STANDARD PROCEDURE , and Refer to REMOVAL , and Refer to INSTALLATION .
