Airbag control unit with part number 98820-EZ62B

What does the airbag control unit 98820-EZ62B do?

Within the restraint system (SRS) of Nissan, the airbag control unit 98820-EZ62B performs the evaluation. It processes the signals from the crash sensors, decides in a crash on the triggering of the airbags and seatbelt pretensioners, and monitors the system continuously. It indicates faults via the airbag warning light.

Triggering depends on a lightning-fast assessment, which is why the comparison runs without interruption. The measured values are compared with stored thresholds, and the unit registers deviations without any action by the driver.

After an accident, the unit stores crash data and locks itself.

Why does the control unit 98820-EZ62B fail?

The most common cause is crash data that remains in the unit after an accident, even if no airbag has triggered. Ageing electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes are also possible.

Crash data remains in the control unit after an accident, even if no airbag has triggered. A normal diagnostic tool cannot erase it, so the fault persists. The other causes concern the ageing of the electronics, moisture at connections and fluctuations in the vehicle's electrical system.

Which cause applies in the individual case is determined only by the examination of the unit.

How can you tell that the 98820-EZ62B is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and the instrument cluster displays an error message. In addition, the diagnostic tool does not establish a connection to the control unit, and the fault memory cannot be cleared.

Typical signs at a glance:

• Airbag warning light permanently or intermittently on
• Error message in the instrument cluster
• Diagnostic tool cannot find the control unit
• Fault memory remains

In an emergency, airbags and seatbelt pretensioners may then not be able to trigger. Please have the finding checked promptly.
