Airbag control unit with part number 68303222AA

What does the airbag control unit 68303222AA do?

The airbag system's control centre in Dodge is the airbag control unit 68303222AA. It reads the crash sensors, determines in an accident within split seconds which airbags and seatbelt pretensioners fire, and keeps the entire system under watch. Detected faults are passed on via the airbag warning light.

While driving, the monitoring continues in the background. If an irregularity is detected, the unit stores an entry in the fault memory.

If an accident occurs, the unit stores crash data and locks itself as a result.

Why does the control unit 68303222AA fail?

Stored crash data from an accident is the most common cause, even if no airbag has deployed. Aged components, cold solder joints, moisture and corrosion at plugs, and voltage spikes, for example from a weak battery or a jump start, are also possible causes.

The crash data is stored in the control unit. An ordinary diagnostic tool cannot reach this data and therefore cannot erase it.

The other causes affect the electronics themselves or their connections. Components age, solder joints can go cold, plug contacts do not tolerate moisture well, and voltage spikes from the vehicle electrical system stress the circuit.

How can you tell that the 68303222AA is defective?

A defect shows up through the airbag warning light in the instrument cluster, which burns permanently or intermittently, through an error message in the display, through a missing connection to the diagnostic tool, and through a fault memory that cannot be emptied.

The warning light is the most important signal, because it displays the fault directly. In an emergency, airbags and seatbelt pretensioners may then fail to deploy, so the warning must be taken seriously.

You make the label comparison on the removed unit: if the number matches, it is the right unit. However, the label says nothing about the condition. For that, have the fault memory read out beforehand, because only this shows whether the control unit itself is the cause or a plug or cable is.

For the same vehicles, we also repair control units with the part numbers 0285015046, 56043128AC, 56043128AD, 68303217AA, 68303218AA, 68346712AA.

How does the repair of the 68303222AA work?

You have the fault memory read out and enclose the log, then disconnect the battery and remove the control unit. Afterwards, you create the repair order online and send the unit in packed.

Airbag24 checks the unit on the test bench, replaces defective components, erases stored crash data and carries out a function test. Airbag24 needs 3–4 working days for this as a rule.

After the test, your own unit is returned to you. 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.

How does the control unit 68303222AA get to Airbag24?

You send the unit to Airbag24 as a parcel or book a UPS pickup for an extra charge. After the repair, UPS brings the unit back to you.

Put the printed repair order into the parcel and cushion the control unit shock-proof.
