Airbag control unit with part number 98221SG110

What does the airbag control unit 98221SG110 do?

The airbag control unit 98221SG110 manages the SRS restraint system in Subaru. It checks the signals from the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners trigger, and monitors the system continuously. It indicates faults via the airbag warning light.

After an accident the unit stores crash data and locks itself.

Why does the control unit 98221SG110 fail?

Stored crash data is the most common cause, even if no airbag has deployed; a normal diagnostic tool does not erase it. Otherwise, aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example with a weak battery or after a jump start, come into question.

Crash data remains stored even if the vehicle then drives without any noticeable problems.

The exact finding is provided only by the examination on the test bench.

How can you tell that the 98221SG110 is defective?

A fault can be recognised above all by the airbag warning light in the instrument cluster, and also by messages and connection problems.

• The airbag warning light stays on or flickers at times.
• An error message appears in the instrument cluster.
• A diagnostic tool cannot connect to the control unit.
• The fault memory cannot be emptied.

The warning light indicates the fault as soon as the system detects it, so you should take this indication seriously. Airbags and seatbelt pretensioners may possibly not trigger in an emergency in the event of a defect.

You should compare the part number on the label of the removed unit with this page so that you have the correct unit. The cause, however, is not determined by this: the fault memory must be read out beforehand, because only it shows whether the control unit or a plug or cable is defective.

For the same vehicles, we also repair control units with the part numbers 98221-SJ370, 98221SG250, 98221SJ001.
