Airbag control unit with part number 98820-3NE0A

What does the airbag control unit 98820-3NE0A do?

The airbag control unit 98820-3NE0A is the central control unit of the SRS restraint system of Nissan. In an accident it decides within milliseconds which airbags and seatbelt pretensioners are triggered.

To do this, the unit evaluates the signals from the crash sensors. It also monitors the system continuously and shows faults via the airbag warning light in the instrument cluster.

After an accident the unit stores crash data and locks itself. Only the repair lifts the lock.

Why does the control unit 98820-3NE0A fail?

Stored crash data is the most common cause, and this applies even when no airbag was triggered in the accident. A normal diagnostic tool cannot erase this data.

At Airbag24 we remove the crash data as part of the repair. There is no obligation for you to carry out any intervention yourself.

Besides the crash data, ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or after a jump start, come into question as causes.

How can you tell that the 98820-3NE0A is defective?

The airbag warning light in the instrument cluster comes on permanently or intermittently. A fault message, a diagnostic tool without a connection to the control unit 98820-3NE0A and a fault memory that cannot be cleared may come with it.

As long as the restraint system is disturbed, airbags and seatbelt pretensioners may fail to trigger in a crash. The finding should therefore be clarified promptly, even if the vehicle otherwise runs normally.
