Airbag control unit with part number 68303635AA

What does the airbag control unit 68303635AA do?

The airbag control unit 68303635AA is the central control unit of the restraint system for Dodge. It evaluates the crash sensors, decides in an emergency whether to trigger airbags and seatbelt pretensioners, and monitors the system. After an accident, it stores crash data and locks itself.

The control unit reports faults in the system via the airbag warning light in the instrument cluster. This way the driver learns early that something in the system is wrong.

Why does the control unit 68303635AA fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered; a normal diagnostic tool cannot delete it. Airbag24 deletes it during the repair. Besides that, aged components and other causes come into consideration.

Crash data alone says little about the condition of the electronics. It merely shows that the unit has registered an incident.

The other causes concern the electronics themselves: components age, solder joints can go cold, and moisture or corrosion affect plug connections.

Voltage spikes, for example from a weak battery or jump-starting, place additional strain on the electronics.

How can you tell that the 68303635AA is defective?

A defect shows when the airbag warning light in the instrument cluster stays on permanently or intermittently, a fault message appears, or the diagnostic tool cannot reach the control unit. A fault memory that cannot be emptied also points to a defect.

The light indicates the fault. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

How does the repair of the 68303635AA work?

First have the fault memory read out and enclose the log, then disconnect the battery and only then remove the control unit; afterwards create a repair order online and send in the well-packed unit. Airbag24 checks it on the test bench, repairs defective components, deletes crash data and carries out a function test; processing usually takes 3–4 working days.

The sequence is fixed for safety reasons, so reading the fault memory always comes first.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
