Airbag control unit with part number 98221FG080

What does the airbag control unit 98221FG080 do?

The airbag control unit 98221FG080 is the central control unit of the restraint system (SRS) for Subaru. It evaluates the signals from the crash sensors and, in a crash, decides whether airbags and seatbelt pretensioners are triggered.

During operation it monitors the entire system. If it detects a fault, it shows this via the airbag warning light in the instrument cluster.

After a crash the unit stores crash data and locks itself. The lock is only lifted by the repair.

Why does the control unit 98221FG080 fail?

The most common cause is crash data stored after an accident, even if no airbag has been triggered; a normal diagnostic tool cannot erase it. Other possible causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

The crash data remains in memory after the accident. During the repair at Airbag24 it is erased.

Components age, solder joints can go cold, and moisture or corrosion impair plug connections. A weak battery or a jump start can also cause voltage spikes that damage the unit.

Which cause applies in an individual case only becomes clear on inspection of the unit.

How can you tell that the 98221FG080 is defective?

A defect shows when the airbag warning light in the instrument cluster lights up permanently or intermittently, an error message appears, the diagnostic tool cannot establish a connection to the control unit, or the fault memory cannot be cleared.

• The airbag warning light is on permanently or intermittently.
• An error message appears in the instrument cluster.
• The diagnostic tool cannot connect to the control unit.
• The fault memory cannot be cleared.

In this condition, airbags and seatbelt pretensioners may not trigger in an emergency. Please therefore have the system checked promptly.
