Airbag control unit with part number 98221FG010

What does the airbag control unit 98221FG010 do?

The airbag control unit 98221FG010 takes over the evaluation of all crash sensors in the restraint system (SRS) of Subaru. In an accident it determines within milliseconds which airbags and seatbelt pretensioners come into use. It monitors the system continuously and reports faults via the airbag warning light.

The system is checked during every journey. After an accident the unit stores crash data and locks itself.

Why does the control unit 98221FG010 fail?

The most common cause at the 98221FG010 is crash data stored after an accident, even if no airbag has triggered. Other causes are aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example with a weak battery or a jump start.

The crash data stays in the memory because a normal diagnostic tool cannot erase it. That is why the fault persists after the accident.

Ageing and cold solder joints develop gradually. Corrosion at plug connections disrupts the contact and thus the signals from the sensors.

Voltage spikes strain the electronics, so weak batteries and jump starts are possible triggers.

How can you tell that the 98221FG010 is defective?

A defect at the 98221FG010 shows first on the airbag warning light in the instrument cluster, which lights up permanently or intermittently. An error message, a missing connection to the diagnostic tool and a fault memory that cannot be cleared confirm this. Then airbags and seatbelt pretensioners may not be able to trigger in an emergency.

• Airbag warning light lights up permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool finds no connection to the control unit
• Fault memory cannot be cleared

Use the part number on the label of the removed unit to check against this page whether it is the right unit; that is all this comparison shows. Also have the fault memory read out, because only this log shows whether the control unit is defective or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 98221FG000, 98221FG040, 98221FG060, 98221FG070.

How does the repair of the 98221FG010 work?

First have the fault memory read out and attach the log to the parcel. Then disconnect the battery before you remove the 98221FG010. Afterwards create a repair order online and pack the unit well.

Airbag24 checks the unit on the test bench, replaces defective components, deletes stored crash data and finally runs a function test.

Processing at Airbag24 usually takes 3–4 working days. Afterwards your own unit comes back to you.

Our repairs come with 2 years' statutory liability for defects.

The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
