Airbag control unit with part number 5QF959655P

What does the airbag control unit 5QF959655P do?

As the SRS control unit for Seat, the airbag control unit 5QF959655P manages the restraint system. It measures the crash sensors, calculates in an accident which airbags and seatbelt pretensioners to trigger, and monitors the system permanently. After an accident it stores crash data and locks itself.

In the background, the controller continuously checks whether all components of the system respond.

If it detects a fault, the airbag warning light comes on and an entry is stored in the fault memory.

Why does the control unit 5QF959655P fail?

The most common cause is crash data that remain in the 5QF959655P after an accident, even if no airbag has deployed; a standard diagnostic tool cannot remove them. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes also play a role.

Airbag24 erases the crash data during the repair. The other causes can only be narrowed down on the unit itself.

Voltage spikes arise, for example, from a weak battery or after a jump start, and can strain the electronics.

How can you tell that the 5QF959655P is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently; this is a warning signal for the 5QF959655P. An error message may appear alongside it, the diagnostic tool finds no connection to the control unit, and the fault memory remains even when it is supposed to be cleared.

The warning signal means that the system has detected a fault, even if the vehicle can still be driven.

In that case, airbags and seatbelt pretensioners may not deploy in an emergency.
