Airbag control unit with part number 98221SJ260

What does the airbag control unit 98221SJ260 do?

The 98221SJ260 is the airbag control unit of the restraint system (SRS) in Subaru, that is, the point that triggers airbags and seatbelt pretensioners. It queries the crash sensors, evaluates their signals within milliseconds and monitors the entire system during operation.

If the control unit detects a fault, it reports it via the airbag warning light. After a crash it stores crash data and locks itself.

It therefore decides in an emergency whether restraint devices are deployed, and it deserves corresponding attention.

Why does the control unit 98221SJ260 fail?

Stored crash data from an accident are the most common cause, even if no airbag has fired. Further causes are aged components, dry joints, moisture and corrosion on plugs, and voltage spikes, for example from a weak battery or jump-starting.

Stored crash data cannot be removed with a conventional diagnostic tool. Airbag24 erases them during the repair.

The other causes relate to electronics, contacts and the power supply. The examination on the test bench determines which of these applies here.

How can you tell that the 98221SJ260 is defective?

A defect shows up as an airbag warning light that lights up permanently or intermittently, as an error message in the instrument cluster, as a lack of connection to the diagnostic tool, and as a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then not trigger.

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

Each of these signs is reason enough to have the system checked. The warning light is the most direct indication of the state of the system.
