Airbag control unit with part number 98221XA10A

What does the airbag control unit 98221XA10A do?

Within the restraint system (SRS) of Subaru, the airbag control unit 98221XA10A takes the decision on triggering. It evaluates crash sensors and determines in an accident, within milliseconds, which airbags and seatbelt pretensioners are triggered.

The unit monitors the system constantly and indicates detected faults via the airbag warning light.

If an accident has occurred, the control unit stores crash data and locks itself. The lock is only lifted by the repair.

Why does the control unit 98221XA10A fail?

Stored crash data after an accident is the most common cause, even if no airbag has deployed. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes are also possible.

Crash data cannot be erased with a conventional diagnostic tool. Airbag24 takes care of this during the repair.

Whether moisture at a plug, a cold solder joint or a voltage spike is causing the failure only becomes clear from the examination.

How can you tell that the 98221XA10A is defective?

The airbag warning light in the instrument cluster stays on permanently or comes on intermittently. A fault message may also appear, the diagnostic tool receives no connection, or the fault memory cannot be cleared.

In that case the airbags and seatbelt pretensioners may possibly not respond in an emergency. That is why it is important not to ignore the light.
