All models are equipped with a with dual air bag system. Unless specific models are mentioned, the following
procedures apply to all models with air bag system.

SYSTEM OPERATION CHECK

1. Ensure negative battery cable is disconnected and isolated. Connect Diagnostic Read-Out Box III (DRB-

III) scan tool to 16-pin Data Link Connector (DLC) located left of steering column at lower edge of
instrument panel. Turn ignition switch to ON position and exit vehicle. Ensure latest version of correct
DRB cartridge is being used.

2. After ensuring there is no one inside vehicle, connect negative battery cable. Using DRB, read and record

active and any stored Diagnostic Trouble Codes (DTCs). If any DTCs are present, diagnose as necessary.
Clear DTCs and recheck for DTCs. If a problem still exists DTC data will not clear.

3. Ignition switch should still be in ON position. Ensure no one is inside vehicle. From a position outside

vehicle and away from air bag modules (in case of air bag deployment), turn ignition switch to OFF
position for about 10 seconds, and then back to ON position. Observe AIR BAG warning light. It should
come on for 6-8 seconds and then go out, indicating system is functioning properly.

4. If AIR BAG warning light fails to come on, comes on and stays on, or comes on while driving, a system

malfunction exists. Perform air bag system self-diagnostics, and repair air bag system.

SERVICE PRECAUTIONS

Observe the following precautions when working with or near air bag systems:

z

Disconnect and isolate negative battery cable before servicing vehicle. Allow system capacitor to
discharge for 2 minutes before removing air bag components.

z

Disable air bag system before servicing any air bag system or steering column component. Failure to do
this may result in accidental air bag deployment and possible personal injury. See DISABLING &
ACTIVATING AIR BAG SYSTEM .

z

Always wear safety glasses when servicing or handling an air bag.

z

Air bag module must be stored in its original special container until used for service. It must be stored in
a clean, dry place, away from sources of extreme heat, sparks and high electrical energy.

z

When placing a live air bag on a bench or other surface, always face air bag and trim cover up, away from
surface. This will reduce motion of module if accidentally deployed.

z

When a steering column has an air bag module attached, never place column on the floor or any other
surface with the steering wheel or air bag module face down.

z

The air bag module inflator assembly contains sodium azide and potassium nitrate. These materials are
poisonous and extremely flammable; contact with acid, water, or heavy metals may produce harmful and
irritating gases.

z

Passenger-side air bag contains argon gas pressurized to over 2500 psi (175.8 kg/cm

2

). DO NOT

attempt to dismantle air bag module or tamper with its inflator. DO NOT puncture, incinerate, or bring air
bag into contact with electricity. DO NOT store air bag at temperatures exceeding 200°F (93°C).

z

After deployment, air bag surface may contain sodium hydroxide deposits, which irritate skin. Sodium
hydroxide is a product of the gas generant combustion. Always wear safety glasses, rubber gloves and a
long-sleeved shirt during clean-up. Wash hands using mild soap and water. Follow correct disposal
procedures.

z

When carrying a live air bag module, point trim cover away from your body to minimize injury in case of
accidental deployment.

z

The horn switch is integral with the air bag module trim cover. Failure to take the proper precautions
could result in accidental, incomplete, or improper air bag deployment and possible personal injury.

z

DO NOT disconnect or connect air bag module while battery is connected. Never disassemble air bag
module. There are no serviceable parts within the module.

z

On Wrangler, when both air bag door bracket "J" nuts are removed from the instrument panel armature,
they must be replaced with 2 NEW "J" nuts. Ensure all fasteners for air bag door are installed. Failure to
do this could result in incomplete, or improper air bag deployment and possible personal injury.

z

The air bag control module contains an impact sensor which enables the system to deploy the air bags.
