Airbag control unit with part number 6Q0909601AE

What does the airbag control unit 6Q0909601AE do?

6Q0909601AE is the SRS control unit of Seat and controls the airbags as well as the seatbelt pretensioners. In a crash it evaluates the sensors and decides within milliseconds which deployment takes place; the system also monitors it during operation.

If it detects a fault, the airbag warning light comes on. After an accident it stores crash data and locks itself; this lock is ended exclusively by the repair.

Why does the control unit 6Q0909601AE fail?

The most common cause is stored crash data from an accident, even without a triggered airbag, which a normal diagnostic tool cannot erase. Further causes are aged components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

The following points come into consideration in detail:

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

Airbag24 erases the crash data during the repair. Which of the other causes applies is determined by the unit during the examination.

How can you tell that the 6Q0909601AE is defective?

A defect shows at the airbag warning light in the instrument cluster as soon as it lights up, or at a fault message in the instrument cluster. In addition the diagnostic tool gets no connection to the control unit, or the fault memory cannot be cleared.

Then airbags and seatbelt pretensioners may fail to deploy in an emergency. Typical signs at a glance:

• airbag warning light lights up constantly or at times
• fault message in the instrument cluster
• no connection between the diagnostic tool and the control unit
• fault memory cannot be cleared

If you see any of these signs, have the system checked promptly.
