Airbag control unit with part number 98820-9GK3B

What does the airbag control unit 98820-9GK3B do?

The airbag control unit 98820-9GK3B forms the central control unit of the restraint system (SRS) for Nissan. It processes the signals from the crash sensors and, in an accident, decides which airbags and seatbelt pretensioners are triggered.

The decision is made within milliseconds. Between accidents the unit monitors the system without interruption and shows faults via the airbag warning light.

After an accident the unit stores crash data and then locks itself.

Why does the control unit 98820-9GK3B fail?

On the 98820-9GK3B, the most common cause is crash data stored after an accident, even if no airbag has triggered. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

An ordinary diagnostic tool cannot erase this crash data; Airbag24 removes it during the repair. The other causes affect the electronics themselves and their connections.

Aged components and cold solder joints only show up during a test. Moisture on plugs and voltage spikes, for example from a weak battery or jump-starting, can likewise cause a failure.

How can you tell that the 98820-9GK3B is defective?

On the 98820-9GK3B, a defect is recognised above all by the airbag warning light, which lights up permanently or from time to time. A fault message in the instrument cluster, a diagnostic tool without a connection to the control unit or a fault memory that cannot be cleared also indicate a defect.

The warning light sits in the instrument cluster, and you see it when you get in or while driving.

In an emergency, airbags and seatbelt pretensioners may not trigger. Have the finding checked promptly.

Airbag24 checks the 98820-9GK3B on the test bench, replaces defective components, erases stored crash data and carries out a function test. Afterwards your own unit goes back to you.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
