Airbag control unit with part number 98820-6AS0A

What does the airbag control unit 98820-6AS0A do?

The airbag control unit 98820-6AS0A is the control unit of the restraint system (SRS) for Infiniti. It evaluates the signals from the crash sensors and determines in an accident which airbags and seatbelt pretensioners are triggered.

The system is monitored continuously, and every fault is shown via the airbag warning light. This lets you spot problems early, without having to take the vehicle apart.

After an accident, the unit stores crash data and locks itself. Only the repair lifts this lock.

Why does the control unit 98820-6AS0A fail?

The unit most often fails because of crash data stored after an accident, even if no airbag has deployed. A standard diagnostic tool cannot erase this data. Other causes include aged components, cold solder joints, moisture and corrosion on plugs, and voltage spikes.

Anyone holding the unit cannot reset the crash data themselves; that remains reserved for the repair. Airbag24 therefore removes the data as part of the repair.

The other causes work through contact problems or voltage fluctuations. Only a check of the unit can reliably identify a weak point.

How can you tell that the 98820-6AS0A is defective?

A defect in the 98820-6AS0A is indicated by an airbag warning light that lights up permanently or intermittently. An error message also appears in the instrument cluster, the diagnostic tool does not find the control unit, and the fault memory cannot be cleared.

These signs are clear and should not be ignored for a long time. They give a clear indication that the system is no longer working fully.

In an emergency, airbags and seatbelt pretensioners may fail to deploy. It is therefore advisable to have the warning checked promptly.
