Airbag control unit with part number 98820-6UT0B

What does the airbag control unit 98820-6UT0B do?

The airbag control unit 98820-6UT0B is the central control unit of the restraint system (SRS) for Nissan. It captures the signals from the crash sensors, decides in a crash which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

The control unit shows faults via the airbag warning light in the instrument cluster. This is how you notice a fault early.

After a crash, it stores crash data and locks itself. The lock is a feature of the entire restraint system. In the background, the control unit processes readings from several sensors at the same time. This evaluation forms the basis of every decision about triggering. Connections to airbags and seatbelt pretensioners are also monitored continuously.

Why does the control unit 98820-6UT0B fail?

The crash data that the control unit stores after an accident is the most common cause, even if no airbag was triggered. A normal diagnostic tool cannot erase it, and Airbag24 erases it during the repair. Other causes are ageing components, cold solder joints, moisture and corrosion, and voltage spikes.

The crash data is the finding that the control unit records after an accident. Without a repair, it remains stored, because a diagnostic tool does not remove it.

The other causes concern electronics that age over time. Solder joints can go cold, and moisture or corrosion on plug connections disturbs the contacts.

How can you tell that the 98820-6UT0B is defective?

The airbag warning light in the instrument cluster lights up permanently or at times, and a fault message appears in the instrument cluster. In addition, the diagnostic tool does not connect to the control unit.

In an emergency, the airbags and seatbelt pretensioners may not trigger while the fault exists. The light indicates the defect and should therefore be taken seriously.

A fault memory that cannot be cleared is a further sign that a closer inspection is needed.
