Airbag control unit with part number 98221CA150

What does the airbag control unit 98221CA150 do?

The airbag control unit 98221CA150 takes over control of the restraint system for Subaru. In an impact it evaluates the sensor signals, determines within milliseconds the triggering of airbags and seatbelt pretensioners, and monitors the system continuously.

Measured values from the sensors flow into the control unit, which makes the decision; the triggering elements carry it out.

The unit indicates faults in the system via the airbag warning light in the instrument cluster. After an accident it also stores crash data, after which it locks itself.

Why does the control unit 98221CA150 fail?

With the control unit 98221CA150, crash data stored after an accident is the most common cause, even if no airbag was deployed. An ordinary diagnostic tool cannot delete it. Other causes are aged electronic components, cold solder joints, moisture and corrosion at connectors, and voltage spikes.

An accident without airbag deployment can also leave crash data behind. The control unit registers the event regardless of which airbags fire.

The other causes concern the electronics inside the unit and its connections. Voltage spikes arise, for example, from a weak battery or jump-starting.

How can you tell that the 98221CA150 is defective?

A defect in the 98221CA150 shows up as the airbag warning light in the instrument cluster staying on permanently or intermittently. In addition, fault messages appear in the instrument cluster, the diagnostic tool cannot find the control unit, and the fault memory remains. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The light is the signal that is noticed fastest. If it does not go out after switching on the ignition, an inspection is advisable.

A diagnostic tool that makes no contact with the control unit also provides an indication. The auditing will show the exact location of the fault.
