Airbag control unit with part number 98221SJ010

What does the airbag control unit 98221SJ010 do?

The airbag control unit 98221SJ010 manages the restraint system (SRS) of Subaru. It checks the crash sensors, evaluates their signals in an accident and decides which airbags and seatbelt pretensioners are triggered.

The unit checks the entire system continuously. If it detects a fault, it shows this via the airbag warning light in the instrument cluster.

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

Why does the control unit 98221SJ010 fail?

The most common cause is crash data that was stored after an accident, even if no airbag triggered. In addition there are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes from the vehicle electrical system.

Crash data cannot be erased with a normal diagnostic tool. Airbag24 erases it during the repair.

Aged components and cold solder joints can impair the function, while moisture and corrosion attack the contacts in plugs. Voltage spikes arise, for example, from a weak battery or a jump start.

How can you tell that the 98221SJ010 is defective?

A defect on the 98221SJ010 shows itself through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. A fault message may also appear, or the diagnostic tool finds no connection to the control unit.

A fault memory that cannot be cleared is another sign of a problem with the unit. In an emergency, airbags and seatbelt pretensioners may then fail to trigger, so take the warning seriously.
