Driver Airbag Module (DAB)
The Driver Airbag Module (DAB) protective trim cover is the most visible part of the driver side airbag system. The module is mounted directly
to the steering wheel. The protective trim cover is fitted to the front of the airbag module and forms a decorative cover in the center of the steering
wheel. Upon airbag deployment, this cover will split at a predetermined breakout line. Located under the airbag module trim cover are the horn
switch, the airbag cushion and the airbag cushion supporting components. The airbag module includes a housing to which the cushion and inflator
are attached and sealed. The airbag module cannot be repaired and must be replaced if deployed or is damaged or defective in any way. The
inflator assembly is mounted to the back of the airbag module. When supplied with the proper electrical signal, the inflator seals the hole in the
airbag cushion so it can discharge the gas it produces directly into the cushion.
THE AIRBAG 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
OR IRRITATING GASES (SODIUM HYDROXIDE IS FORMED IN THE PRESENCE OF MOISTURE) OR COMBUSTIBLE
COMPOUNDS. IN ADDITION, THE PASSENGER AIRBAG MODULE CONTAINS ARGON GAS PRESSURIZED TO OVER 2500 PSI. DO
NOT ATTEMPT TO DISMANTLE AN AIRBAG MODULE OR TAMPER WITH ITS INFLATOR. DO NOT PUNCTURE, INCINERATE OR
BRING INTO CONTACT WITH ELECTRICITY. DO NOT STORE AT TEMPERATURES EXCEEDING 93 ° C (200 ° F).
The DAB is connected to the ACM through a mechanical device called a clock spring. The clockspring allows the DAB to be hardwired through
the steering wheel to the ACM. A yellow quick disconnect connector is located under the steering column at the lower edge of the knee blocker
panel. This connector when disconnected will disable both the DAB and PAB modules.
THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO DIAGNOSE OR
SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING, STEERING COLUMN OR INSTRUMENT PANEL COMPONENTS, YOU
MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. WAIT TWO MINUTES FOR THE
SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE
AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
WHEN A STEERING COLUMN HAS AN AIRBAG MODULE ATTACHED, NEVER PLACE THE COLUMN ON THE FLOOR OR ON
ANY OTHER SURFACE WITH THE STEERING WHEEL OR AIRBAG MODULE FACE DOWN.
Passenger Airbag Module (PAB)
The airbag door on the instrument panel above the glove box is the most visible part of the passenger side airbag system. Under the airbag door are
the airbag cushion and its supporting components. The airbag module includes a housing to which the cushion, inflator and canister of compressed
gas are attached and sealed. The airbag module cannot be repaired and must be replaced if deployed or damaged. The inflator seals the hole in the
airbag cushion so it can discharge the gas it produces directly into the cushion when supplied with the proper electrical signal. The airbag door is
secured to the airbag module and the instrument panel base, and has predetermined breakout lines concealed beneath its decorative cover. Upon
airbag deployment, the airbag door will split at the breakout lines and the door will pivot out of the way. The airbag door is serviced as a unit with
the airbag module. If an airbag module assembly is defective and non-deployed, refer to the Chrysler Corporation current parts return list in the
Warranty Policies and Procedures manual for the proper handling procedures.

MOPAR PARTS CATALOG. SUBSTITUTE PARTS MAY APPEAR INTERCHANGEABLE, BUT INTERNAL DIFFERENCES MAY
RESULT IN INFERIOR OCCUPANT PROTECTION. THE FASTENERS, SCREWS AND BOLTS ORIGINALLY USED FOR THE AIRBAG
SYSTEM COMPONENTS HAVE SPECIAL COATINGS AND ARE SPECIFICALLY DESIGNED FOR THE AIRBAG SYSTEM. THEY
MUST NEVER BE REPLACED WITH ANY SUBSTITUTES. ANYTIME A NEW FASTENER IS NEEDED, REPLACE IT WITH THE
CORRECT FASTENERS PROVIDED IN THE SERVICE PACKAGE OR SPECIFIED IN THE CHRYSLER MOPAR PARTS CATALOG.
