Airbag control unit with part number 6S6T-14B056-KC

What does the airbag control unit 6S6T-14B056-KC do?

The airbag control unit 6S6T-14B056-KC is the control unit of the restraint system (SRS) for Ford. It reads the crash sensors, determines in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

If the unit detects a fault, it indicates this via the airbag warning light in the instrument cluster. That light is therefore the most important warning in everyday use.

After an accident the unit stores crash data and locks itself. The sensor signals converge in the background; you do not have to operate anything.

Why does the control unit 6S6T-14B056-KC fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. Further causes are:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump-start

Crash data cannot be erased with a normal diagnostic tool. It therefore stays in the unit, even when nothing can be seen externally.

The other causes concern the electronics and their connections. Which of them is present is shown only by the read-out.

How can you tell that the 6S6T-14B056-KC is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. In addition there is an error message in the instrument cluster, the diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared. Then airbags and seatbelt pretensioners may not trigger in an emergency.

A lit warning light is a notice you should not ignore. Even a brief illumination indicates a detected fault.

A missing connection to the diagnostic tool may originate from the control unit, but it does not have to. The fault memory provides information on this.

On the one hand, compare the part number on the label of the removed unit with this page, so that you have the right unit in front of you. On the other hand, have the fault memory read out before removal. Only this log shows whether the control unit is defective or a plug or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 8V51-14B321-EE.

How does the repair of the 6S6T-14B056-KC work?

First have the fault memory read out and enclose the log. Then disconnect the battery before removing the control unit. Afterwards create a repair order online and send the unit in well packed.

The sequence is mandatory for safety and protects you and the system. The control unit may only be removed after the battery has been disconnected.

On the test bench, Airbag24 inspects the unit, replaces defective components and erases the crash data. A function test follows. For inspection, repair and testing, Airbag24 generally expects 3–4 working days. Afterwards your own device 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 6S6T-14B056-KC get to Airbag24?

You send the control unit as a parcel, or you book a UPS collection for an extra charge. After the repair, Airbag24 returns it to you by UPS.

Enclose the printed repair order in the parcel and pack the unit shock-proof.
