Airbag control unit with part number 6R0959655B

What does the airbag control unit 6R0959655B do?

For Seat, the airbag control unit 6R0959655B is the central control unit of the restraint system (SRS). It evaluates the signals from the crash sensors and decides in a crash which airbags and seatbelt pretensioners are triggered. It makes this selection in an instant.

The unit also monitors the entire restraint system. If a fault is detected, the signal appears via the airbag warning light in the instrument cluster.

After a crash, the control unit stores crash data and locks itself.

Why does the control unit 6R0959655B fail?

The most common cause is an entry of crash data from an accident, even if no airbag has deployed. With the 6R0959655B, this data cannot be erased with a normal diagnostic tool; Airbag24 erases it during the repair. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage peaks are also possible causes.

The data arises regardless of whether an airbag has deployed, and it remains in the unit.

Aged components, cold solder joints and corrosion on connectors are among the possible reasons as well.

Voltage peaks, for example from a weak battery or a jump-start, can also affect the electronics.

How can you tell that the 6R0959655B is defective?

The airbag warning light in the instrument cluster stays on permanently or only intermittently as soon as the 6R0959655B has a defect. The instrument cluster also shows an error message. The diagnostic tool, moreover, gets no connection to the control unit, and the fault memory cannot be cleared.

Do not push this indicator aside, because it is an early sign of a defect.

In an emergency, airbags and seatbelt pretensioners may then fail to trigger.
