Description

DESCRIPTION

An occupant restraint system is standard factory-installed safety equipment on this vehicle. Available occupant restraints for this vehicle include both active and passive types. Active restraints are those which require the vehicle occupants to take some action to employ, such as fastening a seat belt; while passive restraints require no action by the vehicle occupants to be employed.

ACTIVE RESTRAINTS

The active restraints for this vehicle include:

- Child Restraint Anchors - All vehicles with rear seats are equipped with child seat upper tether anchors that are secured to the upper cab back panel reinforcement. On club cab vehicles the right outboard anchor is a loop of webbing located behind the hinged right upper rear seat back pad, while the center anchor is a stamped D-ring located behind a small hinged access door in the center of the cab back trim panel. On quad cab vehicles all three anchors include a D-ring covered by a loop of webbing strap located behind the rear seat backs. Club cab vehicles also have an upper tether anchor integral to the back of the passenger side front seat cushion frame. Two lower anchors are also provided for the passenger side outboard front and rear seating positions of club cab vehicles, and for each rear outboard seating position on quad cab vehicles. These lower anchors are accessed from the front of the seat where the seat back meets the seat cushion. The child seat tether and lower anchors for the front seat are deleted on quad cab vehicles.
- Front Seat Belts - Both outboard front seating positions are equipped with three-point seat belt systems employing floor sill mounted (club cab) or lower B-pillar mounted (quad cab) inertia latch-type emergency locking retractors, height-adjustable roof rail mounted (club cab) or upper B-pillar mounted (quad cab) turning loops, a traveling lower seat belt anchor secured to the outboard side of the seat frame, and a traveling end-release seat belt buckle secured to the inboard side of the seat frame. The driver side front seat belt buckle includes an integral seat belt switch that detects whether the driver side front seat belt has been fastened. A fixed position lap belt and buckle is provided for vehicles with a center front seating position.
- Rear Seat Belts - On all vehicles equipped with rear seats, each rear seating position is equipped with a three-point seat belt system. The outboard seating position belts employ lower rear pillar mounted inertia latch-type emergency locking retractors, fixed position upper rear pillar mounted turning loops, self-cinching latch plates for compatibility with child seats and fixed lower seat belt anchors secured to the floor panel (club cab) or lower rear pillar (quad cab). The quad cab rear seat center seating position belt has an inertia latch-type emergency locking retractor secured to the rear floor panel and a routing bracket secured to the top of the cab back panel. Fixed end-release buckles are secured to the floor panel on club cab vehicles. On quad cab vehicles the buckle units for the center and left outboard seating positions are secured to the floor panel with the rear seat mounting hardware, while the center anchor buckle and the right outboard buckle are secured to the floor panel with the center retractor mounting hardware.

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 top of 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 - Optional side curtain airbags are available 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 button with the SRS - AIRBAG logo located on the headliner above each roof rail (club cab) or at the top of each B-pillar (quad cab).





The SRS includes the following major components, which are described in further detail elsewhere:

- 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 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 (4) - The Occupant Restraint Controller (ORC) is located on a mount on the floor panel transmission tunnel below the center of the instrument panel.
- Passenger Airbag (2) - The passenger airbag is located in the instrument panel, beneath the passenger airbag door on the top of the instrument panel 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 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 and tensioner units are secured to the right and left floor panel sills on club cab vehicles, or concealed beneath the lower B-pillar trim to the right and left inner B-pillars of quad cab vehicles.
- Seat Track Position Sensor - Certain vehicles may include a seat track position sensor that is located on the inboard side of the upper inboard seat adjuster track on the driver side front seat.
- Side Curtain Airbag (7) - In vehicles equipped with this option, a side curtain airbag is secured to each inside roof side rail above the headliner, and extends from the A-pillar to near the cab back panel.
- Side Impact Sensor (5) - Two side impact sensors are used on vehicles equipped with the optional side curtain airbags, located on the floor panel just behind the front seat crossmember beneath the outboard side of the left and right front seats.

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. 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.
