Airbag control unit with part number 2S6T-14B056-BP

What does the airbag control unit 2S6T-14B056-BP do?

In the restraint system (SRS) at Ford the airbag control unit 2S6T-14B056-BP takes central control. It evaluates the signals from the impact sensors and decides in a crash, within fractions of a second, which airbags and seatbelt pretensioners fire. After an accident it stores crash data and locks itself.

During operation the unit checks the sensors and the firing circuits of the airbags and seatbelt pretensioners. If it finds a fault, it records it and issues a warning via the airbag warning light.

The processing inside the unit remains hidden from you; faults become noticeable through the instrument cluster.

Why does the control unit 2S6T-14B056-BP fail?

Stored crash data is the most common cause when the 2S6T-14B056-BP fails, and this applies even if no airbag fired. An ordinary diagnostic tool cannot erase it. Ageing components, moisture, corrosion and voltage spikes also play a part.

The crash data is held in the memory. Airbag24 erases it as part of the repair.

The other causes concern electronics, plugs and the power supply. Cold solder joints belong here, as do voltage spikes from a weak battery or a jump start.

How can you tell that the 2S6T-14B056-BP is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and a fault message comes with it. The diagnostic tool also finds no connection to the control unit, and the fault memory cannot be cleared. In that case airbags and seatbelt pretensioners may not fire in a crash.

A light of this kind makes the defect visible and calls for a check.
