Passive Restraints
The passive restraints available for this vehicle include the following:
- Dual Front Airbags - Multistage driver and front passenger airbags 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 driver airbag trim cover in the center of the steering wheel and also into the passenger airbag door on the instrument panel above the glove box. Vehicles with the airbag system can also be identified by the airbag indicator, which will illuminate in the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) for about seven seconds 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 the driver and passenger front seat belt retractors to work in conjunction with the dual front airbags.
- Side Curtain Airbags - Side curtain airbags are standard equipment in 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 button with the SRS - AIRBAG logo located on the top of each B-pillar upper trim panel near the headliner.
- Seat Airbags - Seat mounted airbags are optional 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.
The SRS includes the following major components, which are described in further detail elsewhere in this service information:
- Airbag Indicator - The airbag indicator is integral to the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN), which is located on the instrument panel in front of the driver.
- Clockspring - The clockspring is located near the top of the steering column, directly beneath the steering wheel.
- Driver Airbag (4) - The driver airbag is located in the center of the steering wheel, beneath the driver airbag trim cover.
- Driver Knee Blocker - The driver knee blocker is a structural unit secured to the back side of and integral to the instrument panel steering column opening cover.
- Front Impact Sensor (1) - 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.
- Occupant Restraint Controller (2) - The Occupant Restraint Controller (ORC) is located on a mount on the floor panel transmission tunnel forward of the transmission gear selector, and is concealed behind the instrument panel center support.
- Passenger Airbag (3) - The passenger airbag is located in the instrument panel, beneath the passenger airbag door on the instrument panel top cover and above the glove box on the passenger side of the vehicle.
- Passenger Knee Blocker - The passenger knee blocker is a structural reinforcement that is integral to and concealed within the glove box door.
- Seat Airbag (7) - An optional seat (thorax) airbag 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 (6) - 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.
- Seat Track Position Sensor (5) - Certain vehicles may include a seat track position sensor that is located on the inboard side of one of the seat adjuster tracks on both the driver and the passenger front seats.
- Side Curtain Airbag (9) - A side curtain airbag is secured to each inside roof side rail above the headliner, and extends from the A-pillar to just behind the C-pillar.
- Side Impact Sensor (8) - Four side impact sensors are used, two on each side of the vehicle. One sensor is located behind the B-pillar trim near the belt line of each B-pillar and one sensor is located behind the quarter panel trim near the belt line of each C-pillar.
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 SRS 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 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 SYSTEM WIRING DIAGRAMS article . 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.
