Airbag control unit with part number 98820-6BV0A

What does the airbag control unit 98820-6BV0A do?

In the vehicle from Infiniti, the airbag control unit 98820-6BV0A forms the core of the restraint system (SRS). It evaluates the crash sensors, decides within milliseconds which airbags and seatbelt pretensioners fire, and keeps an eye on the system. Any faults that occur are reported via the airbag warning light.

In operation, it continuously checks whether all components work plausibly. Deviations are stored in the fault memory.

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

Why does the control unit 98820-6BV0A fail?

In the 98820-6BV0A, stored crash data is the most common cause, even if no airbag has deployed; a standard diagnostic tool cannot remove it. The other causes include aged electronics, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

The crash data originates from the accident and remains in the unit. Airbag24 removes it during the repair.

Ageing of the electronics also plays a role. Solder joints may have gone cold, and moisture or corrosion attack the contacts. Voltage spikes from the vehicle's electrical system come on top as an additional factor.

How can you tell that the 98820-6BV0A is defective?

On the 98820-6BV0A, the first sign is the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Fault messages accompany it, the diagnostic tool finds no connection to the control unit, or the fault memory cannot be cleared. In that case, airbags and seatbelt pretensioners may not deploy in an emergency.

The warning light is not a minor matter, because it comes from the control unit itself. If it stays on or keeps coming back, the vehicle should be checked.

A fault message or a fault memory that cannot be read out reinforces the finding.
