Airbag control unit with part number BS69-14B056-AA

What does the airbag control unit BS69-14B056-AA do?

The airbag control unit BS69-14B056-AA coordinates the restraint system (SRS) in the Ford vehicle. In an impact it evaluates the crash sensors and determines within milliseconds which airbags and seatbelt pretensioners fire.

Outside an accident the unit continuously checks the system for faults and indicates deviations via the airbag warning light in the instrument cluster.

After an accident the unit stores crash data and locks itself. You notice nothing of this while driving, but a diagnosis does reveal it.

Why does the control unit BS69-14B056-AA fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. Aged electronics, cold solder joints, moisture or corrosion at plug connections, and voltage spikes are further possible causes.

Stored crash data cannot be deleted with a normal diagnostic tool. As long as it remains in memory, the finding on the unit persists.

Aged electronic components and cold solder joints develop over time and can make contacts unreliable.

Moisture and corrosion at plug connections, as well as voltage spikes, for example from a weak battery or from jump-starting, also affect the unit.

How can you tell that the BS69-14B056-AA is defective?

The airbag warning light in the instrument cluster lights up permanently or only intermittently. A fault message appears in the instrument cluster, the diagnostic tool cannot establish a connection to the control unit, and the fault memory cannot be cleared.

The light is a clear indication that the system has detected a deviation. It is not a mere assumption.

In an emergency, airbags and seatbelt pretensioners may then possibly fail to trigger, so a prompt check is advisable.

A comparison of the part number on the label with this page only shows whether it is the correct unit. Whether the control unit itself is defective or a plug or cable is the cause is shown only by the fault memory read out beforehand.

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 BS69-14B056-AA work?

First have the fault memory read out and enclose the log. Then disconnect the battery and only then remove the unit. Next create a repair order online and send the well-packed unit.

The order is fixed for safety reasons. Airbag24 checks the unit on the test bench, repairs defective components, deletes stored crash data and carries out a function test; checking, repairing and testing usually take 3–4 working days.

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 BS69-14B056-AA get to Airbag24?

You send the unit as a parcel or you book a UPS collection for an extra charge. After the repair Airbag24 sends it back by UPS.

Print the repair order and place it in the parcel. Pack the unit so that it is shock-resistant.
