Airbag control unit with part number 98820-EZ30B

What does the airbag control unit 98820-EZ30B do?

The airbag control unit 98820-EZ30B is the control unit of the SRS restraint system in Nissan. It processes signals from the crash sensors, determines in a crash within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It shows faults via the airbag warning light.

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

The control unit is constantly active during normal operation and monitors its surroundings.

Why does the control unit 98820-EZ30B fail?

The most common cause is crash data stored after an accident, even if no airbag has opened. Further causes are ageing components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Stored crash data cannot be deleted with an ordinary diagnostic tool. Airbag24 deletes it during the repair.

The other causes lie in the electronics themselves or in their connections. Ageing components and cold solder joints are typical examples, as is moisture in the plug connections. Voltage spikes arise, for example, from a weak battery or from jump-starting.

How can you tell that the 98820-EZ30B is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, a fault message appears in the instrument cluster, the diagnostic tool receives no connection to the control unit, and the fault memory cannot be cleared. Airbags and seatbelt pretensioners may then not trigger in an emergency.

The warning light shows the defect, so you do not have to wait for an incidental discovery. Take the sign seriously and have it checked.

If the light only flickers occasionally, that is also a reason for a check.
