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

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

The airbag control unit 6S6T-14B056-BP is part of the central control of the restraint system (SRS) in Ford. It measures the impact of an accident via the crash sensors, decides within milliseconds on triggering, and monitors the system continuously. After an accident it stores crash data and locks itself.

Evaluating the sensor signals is the core of its task.

Faults that the unit detects are shown via the airbag warning light in the instrument cluster.

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

On the 6S6T-14B056-BP, the most common cause after an accident is stored crash data, even where no airbag has deployed. Ageing electronics, cold solder joints, moisture and corrosion, and voltage spikes come on top of this.

Crash data stays in the unit until it is removed. A standard diagnostic tool cannot erase it; Airbag24 removes it during the repair.

Electronics age, and solder joints can go cold or break over time. Moisture and corrosion attack plug connections.

Voltage spikes occur, for example, when the battery is weak or a jump start is connected.

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

A defect on the 6S6T-14B056-BP can be recognised by the airbag warning light in the instrument cluster, which lights up continuously or intermittently.

Further signs are:

• error message in the instrument cluster
• no connection between the diagnostic tool and the control unit
• fault memory that cannot be erased

With these signs, airbags and seatbelt pretensioners may not trigger in an emergency, which is exactly why a check makes sense.
