Airbag control unit with part number 98820-EZB0A

What does the airbag control unit 98820-EZB0A do?

The airbag control unit 98820-EZB0A controls the restraint system (SRS) of Nissan. It evaluates the crash sensors, decides in an accident within milliseconds on the triggering of airbags and seatbelt pretensioners, and monitors the system during operation.

Faults are shown by the control unit via the airbag warning light in the instrument cluster. The light is therefore the direct link between the restraint system and the driver.

After an accident it stores crash data and locks itself. The lock is only lifted by the repair.

Why does the control unit 98820-EZB0A fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool does not erase it. Further causes are ageing electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes, for example from a weak battery.

The crash data stays in the unit until it is removed during the repair. For that reason the fault appears even when nothing on the vehicle looks any more out of order from outside.

The other causes concern mainly the electronics and their connections. Damp plugs and corrosion on contacts can cause faults that show up in the display only gradually.

How can you tell that the 98820-EZB0A is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, an error message appears in the instrument cluster, the diagnostic tool gets no connection to the control unit, and the fault memory cannot be erased. In an emergency airbags and seatbelt pretensioners may then possibly not deploy.

Look out for these signs:

• The airbag warning light stays on permanently or keeps coming back.
• An error message appears in the instrument cluster.
• The diagnostic tool cannot reach the control unit.
• The fault memory remains populated despite a clearing attempt.

Each of these signs is a reason to have the system checked before you continue using the vehicle in everyday traffic.
