Airbag control unit with part number 98820-6AU0A

What does the airbag control unit 98820-6AU0A do?

The airbag control unit 98820-6AU0A controls the restraint system (SRS) for Infiniti. It receives the signals from the crash sensors and, in an accident, selects the suitable airbags and seatbelt pretensioners within milliseconds.

The unit monitors the entire system continuously and reports faults via the airbag warning light.

After an accident it creates crash data and locks itself. The lock is lifted only by the repair.

Why does the control unit 98820-6AU0A fail?

The most common cause is crash data stored after an accident, even if no airbag was triggered. A normal diagnostic tool cannot erase it; Airbag24 removes it during the repair. In addition there are aged electronics, cold solder joints, moisture and corrosion on plugs, and voltage spikes, for example from a weak battery or jump-starting.

The other causes are general in nature. Electronics age, solder joints can be cold, and moisture or corrosion attack plug connections.

How can you tell that the 98820-6AU0A is defective?

A defect shows up on the airbag warning light when it lights up permanently or intermittently. Fault messages in the instrument cluster and a fault memory that cannot be cleared are also typical.

• Airbag warning light on permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool does not connect to the control unit
• Fault memory cannot be cleared

In this state, airbags and seatbelt pretensioners may not trigger in an emergency. Take the warning seriously.
