Airbag control unit with part number 98820-6UJ0B

What does the airbag control unit 98820-6UJ0B do?

The airbag control unit 98820-6UJ0B forms the control centre of the SRS restraint system for Nissan. It reads out the crash sensors, determines within milliseconds which airbags and seatbelt pretensioners fire, and monitors the entire system continuously. Faults appear via the airbag warning light.

After an accident, it stores crash data and locks itself.

In normal driving, the control unit hardly stands out as long as all components are in order.

Why does the control unit 98820-6UJ0B fail?

Stored crash data is considered the most common cause with the 98820-6UJ0B, even when no airbag fired. Added to this are aged components, cold solder joints, moisture and corrosion, as well as voltage spikes.

After an accident, crash data stays in the memory, even if no airbag was deployed. A normal diagnostic tool cannot reach it; Airbag24 erases it during the repair.

The other causes mainly concern the electronics themselves. Components age, solder joints can go cold, and voltage spikes arise, for example, with a weak battery or jump-starting.

How can you tell that the 98820-6UJ0B is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and the instrument cluster shows an error message. The diagnostic tool finds no connection to the control unit 98820-6UJ0B, and the fault memory cannot be cleared.

Even a single one of these signs deserves attention, because a fault makes itself noticed this early.

In an emergency, airbags and seatbelt pretensioners may not be able to deploy. A prompt check is therefore worthwhile as soon as the light comes on.
