Airbag control unit with part number 5S6T-14B056-HA

What does the airbag control unit 5S6T-14B056-HA do?

The 5S6T-14B056-HA is the airbag control unit of the restraint system (SRS) of Ford. In an impact, it calculates within milliseconds from the crash sensors which airbags and seatbelt pretensioners are to be triggered.

In everyday use, it works in the background and constantly checks whether the system is intact. A detected fault is brought to your attention via the airbag warning light.

After an accident, it stores crash data and locks itself. This lock affects the control unit itself and is more than a mere notice.

Why does the control unit 5S6T-14B056-HA fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Further causes include aged electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes.

Crash data cannot be removed with a standard diagnostic tool. It therefore remains in memory, even if the vehicle drives normally after the event.

Electronics age, and solder joints can become cold over time. Moisture and corrosion impair plug contacts, while voltage spikes, for example from a weak battery or jump-starting, stress the electronics.

How can you tell that the 5S6T-14B056-HA is defective?

A defect shows itself in several ways at once: the airbag warning light is on, and the diagnostic tool finds no contact with the control unit. In addition, there is a fault memory that cannot be cleared.

• Airbag warning light lights up permanently or intermittently
• Error message in the instrument cluster
• No connection between diagnostic tool and control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then possibly fail to deploy. The warning light should therefore not be ignored.

Whether the control unit is the cause will only be revealed by the fault memory.

Which vehicles is the 5S6T-14B056-HA fitted in?

Compare the number on the label with this page. This only shows that it is the correct unit. Whether the control unit itself is defective is answered only by the fault memory read out in advance, because a plug or a cable can just as well be the cause.

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