Airbag control unit with part number 6RD959655F

What does the airbag control unit 6RD959655F do?

The airbag control unit 6RD959655F manages the SRS restraint system of Volkswagen. It reads the crash sensors, determines in an accident within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the entire system continuously.

The faults it detects are shown via the airbag warning light in the instrument cluster.

After an accident, it stores crash data and locks itself.

Why does the control unit 6RD959655F fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Other causes are aged electronic components, cold solder joints, moisture at plug connections and voltage spikes.

A normal diagnostic tool cannot erase the crash data. Airbag24 erases it during the repair.

Other causes in detail:

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

Only the examination shows whether one of these applies.

How can you tell that the 6RD959655F is defective?

The airbag warning light in the instrument cluster lights up constantly or intermittently, and a fault message appears in the instrument cluster. In addition, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

The signs in detail:

• airbag warning light that lights up constantly or intermittently
• fault message in the instrument cluster
• no connection setup to the diagnostic tool
• fault memory that cannot be cleared

If you notice these signs, airbags and seatbelt pretensioners may fail to deploy in an emergency. A prompt check is therefore advisable.
