Airbag control unit with part number 98820-6RU0B

What does the airbag control unit 98820-6RU0B do?

The 98820-6RU0B coordinates the SRS restraint system of Nissan as the airbag control unit. From the signals of the crash sensors it calculates within milliseconds which airbags and seatbelt pretensioners are triggered in a crash.

Even outside a crash, it checks whether the system is working, and it reports faults via the airbag warning light.

After a crash it stores crash data and locks itself.

Why does the control unit 98820-6RU0B fail?

The most common cause is crash data after an accident, even if no airbag was triggered; a standard diagnostic tool does not erase it. The other causes are ageing of the electronics, cold solder joints, moisture and corrosion on plugs, and voltage spikes when starting or during a jump start.

The crash data remains in memory, even when nothing outwardly visible is wrong with the airbags. Airbag24 erases it during the repair.

Electronics, solder joints and plug connections are the areas where the other causes take effect. Which cause applies in your case only becomes clear during the inspection.

How can you tell that the 98820-6RU0B is defective?

A defect shows up through the airbag warning light, which lights up permanently or intermittently, through fault messages in the instrument cluster, through a diagnostic tool without connection to the control unit, and through a fault memory that cannot be cleared. Airbags and seatbelt pretensioners may then fail to deploy in an emergency.

The signs are these in detail:

• warning light in the instrument cluster stays on
• message in the instrument cluster
• diagnostic tool cannot reach the control unit
• fault memory cannot be cleared

The warning light is a clear indication. Do not ignore it, but have the fault memory read out.
