Airbag control unit with part number 98820-6AR0A

What does the airbag control unit 98820-6AR0A do?

The airbag control unit 98820-6AR0A controls the restraint systems (SRS) of Infiniti. It evaluates the crash sensors and determines in an accident, within milliseconds, which airbags and seatbelt pretensioners trigger.

While driving it continuously checks the system. If it detects a fault, it shows this via the airbag warning light in the instrument cluster.

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

Why does the control unit 98820-6AR0A fail?

The most common cause is crash data stored in the 98820-6AR0A after an accident, even without a triggered airbag. An ordinary diagnostic tool cannot delete this data. Other causes are aged components, cold solder joints, moisture at plug connectors and voltage spikes.

The crash data sits in the control unit and is deleted at Airbag24 during the repair.

The other causes lie in the electronics or their connections. Components age over time, solder joints can go cold, and moisture or corrosion attack the plugs. Voltage spikes from a weak battery or a jump start can also trigger a fault.

How can you tell that the 98820-6AR0A is defective?

The airbag warning light indicates a defect in the 98820-6AR0A when it lights up in the instrument cluster permanently or intermittently. In an emergency, airbags and seatbelt pretensioners may then possibly not trigger.

The following features also point to the defect:

• Airbag warning light on permanently or intermittently
• Error message in the instrument cluster
• Connection from the diagnostic tool to the control unit missing
• Fault memory cannot be cleared

If any of these features occurs, have the system checked.
