Airbag control unit with part number 6R0959655E

What does the airbag control unit 6R0959655E do?

The airbag control unit 6R0959655E coordinates the SRS restraint system for Seat. It evaluates the crash sensors, decides in an accident within milliseconds whether to trigger airbags and seatbelt pretensioners, and checks the system continuously. After an accident it stores crash data and locks itself.

The unit indicates faults via the airbag warning light in the instrument cluster.

The connection to sensors and triggers runs via cables, which must work reliably in operation.

Why does the control unit 6R0959655E fail?

The most common cause is that crash data has been stored after an accident, even if no airbag has deployed; a standard diagnostic tool cannot erase it. Other possible causes are aged components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

The impact leaves the crash data in the memory, and it stays there until it is removed.

The other causes have nothing to do with the accident. Electronics age, solder joints can go cold, and moisture and corrosion damage plug connectors. A weak battery or a jump start can generate voltage spikes.

How can you tell that the 6R0959655E is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, a fault message is shown in the instrument cluster, and the diagnostic tool cannot reach the control unit. A fault memory that cannot be cleared confirms this. Airbags and seatbelt pretensioners may then fail to deploy in an emergency.

The following signs can occur:

• Airbag warning light that stays on permanently or intermittently
• Fault message in the instrument cluster
• Missing connection to the diagnostic tool
• Fault memory that cannot be cleared

Have the system checked as soon as one of these signs appears.
