Passive Restraints
The passive restraints available for this vehicle include the following:
- 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 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 front seat belt retractors mounted on the lower inner B-pillars to work in conjunction with the dual front airbags. Vehicles built for domestic markets also have a pyrotechnic-type seat belt tensioner integral to the front passenger side seat belt buckle mounted on the inboard side of the seat cushion frame.
- Seat Airbags - Seat AirBags (SAB) (also known as pelvic and thoracic airbags) integrated into the outboard side of each front seat back 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 (3) - The Driver AirBag (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 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 the front end module carrier on either side of the radiator and inboard of the headlamp within the engine compartment.
- Occupant Detection Sensor - An Occupant Detection Sensor (ODS) is located on the top of the seat cushion foam or seat cushion heater mat of the passenger side front seat in domestic market vehicles.
- Occupant Restraint Controller (4) - The Occupant Restraint Controller (ORC) is located on a mount on the floor panel transmission tunnel rearward of the transmission gear selector, and is concealed beneath the center floor console.
- Passenger Airbag (2) - The Passenger AirBag (PAB) is located in the instrument panel, beneath the PAB door on the instrument panel 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 (6) - An optional Seat AirBag (SAB) (also known as a pelvic and thoracic airbag) is secured to each outboard front seat back frame, where it is concealed beneath the seat back trim cover and foam.
- Seat Belt Tensioner (8) - A seat belt tensioner is integral to both front seat belt retractor units on vehicles equipped with dual front airbags, and to the front passenger seat buckle of domestic market vehicles. The seat belt retractor tensioner units are secured to each lower inner B-pillar and are concealed behind the lower B-pillar trim. The seat belt buckle tensioner is secured to the inboard rear corner of the passenger front seat cushion frame.
- Seat Track Position Sensor (5) - A Seat Track Position Sensor (STPS) is located on the inboard side of one of the seat adjuster tracks on the driver and passenger side front seats.
- Side Impact Sensor (7) - Two side impact sensors are used on vehicles equipped with the optional seat airbags, one on each side of the vehicle. One sensor is located behind the B-pillar trim near the belt line of each B-pillar.
The ORC and the EMIC 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 EMIC. Refer to COMMUNICATION, 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 wiring information. 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.
