Airbag control unit with part number 98221VC000

What does the airbag control unit 98221VC000 do?

The airbag control unit 98221VC000 belongs to the restraint system (SRS) of Subaru. It evaluates the sensor signals, determines in a crash which airbags and seatbelt pretensioners respond, and keeps an eye on the system. After an accident it stores crash data and locks itself.

It indicates the state of the system via the airbag warning light in the instrument cluster.

Why does the control unit 98221VC000 fail?

The most common cause of failure of the 98221VC000 is stored crash data, even without a deployed airbag. It cannot be removed with an ordinary diagnostic tool; Airbag24 erases it during the repair.

Other possible causes are:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 98221VC000 is defective?

The airbag warning light on the 98221VC000 stays on continuously or intermittently, along with an error message, a missing connection to the diagnostic tool, or a fault memory that cannot be erased. The airbags and seatbelt pretensioners could then fail to deploy in an emergency.

The signal comes directly from the system and is therefore not a guess. Have it checked promptly.
