What does the airbag control unit D3BT-14B321-AF do?
The airbag control unit D3BT-14B321-AF coordinates the restraint system (SRS) of Ford in the vehicle. It checks the signals from the crash sensors, decides within milliseconds in a crash which airbags and seatbelt pretensioners fire, and keeps the system under constant watch. Faults appear via the airbag warning light.
Between events, the unit works as a guardian: it measures whether sensors, firing circuits and wiring are in order and records deviations in the fault memory.
After an accident, it records crash data and then locks itself.
Why does the control unit D3BT-14B321-AF fail?
Most often the cause is crash data stored after an accident, even if no airbag has deployed; a standard diagnostic tool cannot reach it. Added to this are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes such as those from a weak battery or jump-starting.
The crash data remains in the control unit until it is removed during the repair. Airbag24 does exactly that.
The remaining causes tend to work slowly. Moisture and corrosion attack the contacts, and voltage spikes stress the electronics.
How can you tell that the D3BT-14B321-AF is defective?
The airbag warning light in the instrument cluster lights up permanently or intermittently. In addition, a fault message appears in the instrument cluster, the diagnostic tool receives no connection to the control unit, and the fault memory cannot be cleared.
The warning light exists precisely to indicate a finding. It does not stay silent when something is wrong.
With such a finding, airbags and seatbelt pretensioners may not deploy in an emergency.

On the one hand, compare the part number on the label of the removed unit with this page. This only confirms that the correct unit is present. On the other hand, have the fault memory read out beforehand. Only this log shows whether the control unit is defective or whether a plug or cable is the cause.
For the same vehicles, we also repair control units with the part numbers C1BT-14B321-CF, H1BT-14B321-AH, H1BT-14B321-AJ.
How does the repair of the D3BT-14B321-AF work?
You have the fault memory read out and enclose the log, then disconnect the battery and only then remove the control unit. Next, create a repair order online and send the unit in, well packed. Airbag24 checks, repairs and tests within 3–4 working days as a rule.
The sequence is mandatory, because the safety of the system depends on it.
At Airbag24, the unit is checked on the test bench, defective components are replaced, the crash data is deleted and a function test is finally carried out. Afterwards your own unit goes back 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 D3BT-14B321-AF get to Airbag24?
You send the unit as a parcel or book a collection by UPS for an extra charge. After the repair, Airbag24 returns the unit to you by UPS.
The printed repair order goes into the parcel, and the unit is packed shock-proof.
