What does the airbag control unit 56D959655D do?
The airbag control unit 56D959655D coordinates the restraint system (SRS) in Seat. It processes the data from the crash sensors, selects within milliseconds in a crash which airbags and seatbelt pretensioners fire, and monitors the system constantly.
A fault appears via the airbag warning light. After an accident the unit writes crash data and then remains locked.
Why does the control unit 56D959655D fail?
The most common cause is crash data stored after an accident, even if no airbag fired. A diagnostic tool used in the usual way cannot remove them. Aged components, cold solder joints, moisture and corrosion on plug connections, as well as voltage spikes may also contribute.
Crash data arise from the accident itself and remain in the control unit until they are removed.
Other causes act gradually: components age, solder joints lose contact, and moisture attacks the plugs. Voltage spikes, for example from a weak battery or jump-starting, put additional strain on the electronics.
How can you tell that the 56D959655D is defective?
An airbag warning light that stays lit continuously or only now and then, an error message in the instrument cluster, a diagnostic tool without connection to the control unit, and a fault memory that cannot be cleared are the typical signs. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.
The instrument cluster is the first point of contact, because the warning light reports the fault there. After the light first comes on, have the system checked promptly.
