Airbag control unit with part number 98221CA190

What does the airbag control unit 98221CA190 do?

The control centre of the restraint system (SRS) in Subaru is the airbag control unit 98221CA190. It evaluates the crash sensors, selects the airbags and seatbelt pretensioners to be triggered within milliseconds in an accident, and monitors the system continuously. After an accident it stores crash data and locks itself.

The unit issues faults via the airbag warning light. This gives it an overview of the state of the entire system.

Why does the control unit 98221CA190 fail?

The most common cause is stored crash data, even without a triggered airbag; a normal diagnostic tool cannot erase it. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump start, also play a part. Airbag24 erases the crash data during the repair.

The crash data sits in the memory of the control unit, that is, records of the accident. The other causes affect the electronics and their connections.

How can you tell that the 98221CA190 is defective?

Typical is the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Added to this are an error message in the instrument cluster, a diagnostic tool with no connection to the control unit, and a fault memory that cannot be cleared. In an emergency it can then happen that airbags and seatbelt pretensioners do not trigger.

Take this warning seriously and have it checked rather than ignoring it. The warning light is the place where the electronics indicate the fault.
