Airbag System Components

The airbag system consists of the next:

• Occupant Restraint Control Module
• Airbag Warning Light
• Driver Airbag
• Passenger Airbag
• Side Curtain Airbags above Side Windows (If Equipped)
• Side Remote Acceleration Sensors (If Equipped)
• Steering Wheel and Column
• Instrument Panel
• Interconnecting Wiring
• Knee Impact Bolsters
• Front Acceleration Sensors
• Driver and Front Passenger Seat Belt Pretensioner
• Occupant Classification System (OCS) – Front Passenger Seat Only
• Occupant Classification Module
• Passenger Airbag Disable (PAD) Indicator Light
• Weight Sensors

How The Airbag System Works

The Occupant Restraint Control (ORC) Module determines if a frontal collision is extreme sufficient to require the airbags to inflate. The entrance airbag inflators are designed to supply completely different charges of airbag inflation from route supplied by the ORC. The ORC can also modify the speed of inflation based mostly on the occupant dimension supplied by the Occupant Classification Module. The ORC is not going to detect roll over, or rear impacts.

The ORC additionally displays the readiness of the digital elements of the system every time the ignition change is within the START or ON positions. These embrace all the gadgets listed above besides the knee bolster, the instrument panel, and the steering wheel and column. If the secret’s within the LOCK place, within the ACC place, or not within the ignition, the airbags aren’t on and won’t inflate.

Also, the ORC activates the “Airbag Warning Light” and “PAD Indicator Light” for six to eight seconds for a self-check when the ignition is first turned on. After the self-check, the “Airbag Warning Light” will flip off. The “PAD Indicator Light” will operate usually. If the ORC detects a malfunction in any a part of the system, it activates the “Airbag Warning Light” both momentarily or constantly. A single chime will sound if the sunshine comes on once more after preliminary begin up.

WARNING!

Ignoring the “Airbag Warning Light” in your instrument panel might imply you received’t have the airbags to guard you in a collision. If the sunshine doesn’t come on, stays on after you begin the automobile, or if it comes on as you drive, have the airbag system rhPrked instantly.

Passenger Airbag Disable function

The Passenger Airbag Disable (PAD) Indicator Light (an amber mild positioned within the middle of the instrument panel) tells the driving force and entrance passenger when the entrance passenger airbag is turned off. The “PAD Indicator Light” illuminates the phrases “PASS AIR BAG OFF” to point out that the passenger airbag is not going to inflate throughout a collision requiring airbags. When the best entrance passenger seat is empty or when very mild objects are positioned on the seat, the passenger airbag is not going to inflate regardless that the “PAD Indicator Light” is just not illuminated.

The “PAD Indicator Light” shouldn’t be illuminated when youngsters, most kids in a forward-facing baby restraint or booster seats, most kids that may correctly put on the automobile’s seat belt, and when an grownup passenger is correctly seated within the entrance passenger seat. In this case, the airbag is able to be inflated if a collision requiring an airbag happens.

For virtually all correctly put in rear going through baby restraints, the “PAD Indicator Light” can be illuminated indicating that the entrance passenger airbag is turned off and won’t inflate. If the “PAD Indicator Light” is just not illuminated, DO NOT assume the airbag is turned off and transfer the kid restraint to the rear seat. A deploying passenger airbag may cause dying or critical harm to a toddler in a rear going through toddler seat.

NOTE: Even although this automobile is provided with an Occupant Classification System, kids 12 years and beneath ought to at all times experience buckled up in a rear seat in an acceptable baby restraint.

Grocery Bags, Heavy Briefcases and Other Relatively Light Objects ON OFF
Empty or Very Small Objects OFF OFF

Occupant Classification System (OCS)

The Occupant Classification System is a part of a Federally regulated security system required for this automobile. It is designed to show off the entrance passenger airbag within the unlikely occasion {that a} rear-facing toddler seat is within the entrance passenger seat.

NOTE: Children 12 years and beneath ought to at all times experience buckled up in a rear seat in an acceptable baby restraint.

The OCS classifies an occupant utilizing weight sensors mounted within the base of the entrance passenger seat. Any weight on the seat can be sensed by the system. Objects hanging on the seat or different passengers pushing down on the seat can even be sensed. The weight of an grownup will trigger the system to show the airbag on. In this case, the OCS has categorized the occupant of the seat as an grownup. An grownup occupant wants to sit down in a standard place (with their toes on or close to the ground) to be able to be correctly categorized. Reclining the seat again too far might change how an occupant is classed by the OCS.

Drivers and grownup passengers ought to confirm that the “PAD Indicator Light” is just not illuminated when an grownup is using within the entrance passenger seat. If an grownup occupant’s weight is transferred to a different a part of the automobile (just like the door or instrument panel), the load sensors within the seat might not correctly classify the occupant. Objects lodged beneath the seat or between the seat and the middle console can forestall the occupant’s weight from being measured correctly and should end result within the occupant being improperly categorized. Ensure that the entrance passenger seat again doesn’t contact something positioned on the again seat as a result of this may additionally have an effect on occupant classification.

The Occupant Classification Module (OCM) is positioned beneath the entrance passenger seat. The OCM classifies the occupant into classes based mostly on the measurements made by the seat weight sensors. The OCM communicates with the Occupant Restraint Control (ORC) Module. The ORC makes use of the occupant class to find out whether or not the entrance passenger airbag ought to be turned off. It additionally determines the speed of airbag inflation throughout a collision.

The new 2005 Grand Cherokee has 4 Weight Sensors positioned between the seat and the ground pan. The weight sensors measure utilized weight and transfers that info to the OCM.

he Side Impact SRS Side Curtain Airbags are designed to activate solely in sure facet collisions. When the ORC (with facet influence choice) detects a collision requiring the facet curtain airbag to inflate, it indicators the inflators on the crash facet of the automobile. A amount of unhazardous fuel is generated to inflate the facet curtain airbag. The inflating facet curtain airbag pushes the surface fringe of the headliner out of the best way and covers the window. The airbag inflates in about 30 milliseconds (about one quarter of the time it takes to blink your eyes) with sufficient drive to injure you in case you are not belted and seated correctly, or if gadgets are positioned within the space the place the facet curtain airbag inflates. This particularly applies to kids. The facet curtain airbag is barely about 3-1/2 inches (9 cm) thick when it’s inflated.

The Knee Impact Bolsters assist shield the knees of the driving force and the entrance passenger, and place everybody for one of the best interplay with the entrance airbag.

The entrance passenger seat meeting incorporates crucial elements that have an effect on the entrance passenger airbag deployment. Correctly functioning entrance passenger seat elements are crucial for the Occupant Classification System (OCS) to correctly classify the entrance passenger and calculate the right airbag deployment. Do not make any modifications to the entrance passenger seat elements, meeting, or to the seat cowl.

The following necessities have to be strictly adhered to:

• Do not modify the entrance passenger seat meeting or elements in any approach.
