Airbag control unit with part number 68303226AA

What does the airbag control unit 68303226AA do?

The airbag control unit 68303226AA coordinates the triggering of the airbags and seatbelt pretensioners within the restraint system (SRS) of Dodge. It evaluates the signals from the crash sensors, decides within a fraction of a second in the event of an accident, and monitors the system continuously. It indicates faults via the airbag warning light.

After an accident the unit stores crash data and locks itself. Without a working control unit, the interaction of the protection systems remains incomplete.

Why does the control unit 68303226AA fail?

Stored crash data is the most common cause with the 68303226AA, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Other causes include aged electronic components, cold solder joints, moisture and corrosion on connectors, and voltage spikes.

Trying to erase the data yourself does not help; Airbag24 erases it during the repair. A weak battery or a jump start can cause voltage spikes that put additional strain on the unit.

How can you tell that the 68303226AA is defective?

A defect in the 68303226AA shows primarily as the airbag warning light in the instrument cluster. Error messages and read-out errors also point to one.

• The airbag warning light in the instrument cluster stays on permanently or intermittently.
• An error message appears in the instrument cluster.
• The diagnostic tool cannot connect to the control unit.
• The fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

A lit warning light is therefore not a trivial matter and must be taken seriously.
