Airbag control unit with part number 68303224AA

What does the airbag control unit 68303224AA do?

The airbag control unit 68303224AA is the central unit of the restraint system (SRS) of Dodge. It evaluates crash sensors, determines in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and checks the system constantly. It reports detected faults via the airbag warning light.

The test routines run in the background. They cover sensors, wiring and the unit's own function; faults are stored by the unit in the fault memory.

After an accident the unit stores crash data and locks itself.

Why does the control unit 68303224AA fail?

The most common trigger of a failure of the 68303224AA is crash data from an accident, even if the airbag has not triggered; a normal diagnostic tool cannot erase it. Further causes are aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or a jump start.

Airbag24 erases the crash data during the repair.

The other causes are electronic in nature: components age, solder joints can go cold, and moisture attacks plug connections.

How can you tell that the 68303224AA is defective?

A defect in the 68303224AA shows itself through warning signs such as the airbag warning light, error messages and a fault memory that cannot be erased. In an emergency, airbags and seatbelt pretensioners may then possibly not trigger.

Typical signs at a glance:

• airbag warning light in the instrument cluster, permanently or intermittently
• error message in the instrument cluster
• no connection between diagnostic tool and control unit
• fault memory cannot be erased

Have such signs checked promptly. The warning light is the most important signal for this.
