Airbag control unit with part number 98820-5RV0B

What does the airbag control unit 98820-5RV0B do?

The airbag control unit 98820-5RV0B is the central control unit for the SRS of Nissan. It reads the crash sensors, determines in an accident, within milliseconds, the triggering of the airbags and seatbelt pretensioners, and monitors the system continuously. After an accident, it stores crash data and locks itself.

The unit detects faults in the system itself and shows them via the airbag warning light in the instrument cluster. The lock after an accident is lifted only by the repair.

Why does the control unit 98820-5RV0B fail?

Stored crash data after an accident is the most common cause with the 98820-5RV0B, even if no airbag has deployed. A normal diagnostic tool cannot remove this data. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example with a weak battery or a jump start, are also causes.

Airbag24 deletes the crash data during the repair. Until then, it remains in the memory of the unit.

The other causes concern mainly the electronics itself and its connections. Solder joints can go cold, plugs corrode through moisture, and components age over time.

How can you tell that the 98820-5RV0B is defective?

The airbag warning light in the instrument cluster lights up on the 98820-5RV0B constantly or intermittently. Further signs are error messages in the instrument cluster, no connection of the diagnostic tool to the control unit, and a fault memory that cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may fail to deploy in the event of a defect. A single sign does not yet prove the cause; only evaluation of the fault memory clarifies that.

Compare the part number on the label of the removed unit with this page. That only shows that it is the right unit, not the cause. Therefore, ask for the fault memory to be read out beforehand, because only this log shows whether the control unit is defective or whether a plug or cable is the cause.
