Airbag control unit with part number 98820-9WD0A

What does the airbag control unit 98820-9WD0A do?

As the central control unit of the restraint system (SRS) of Nissan, the airbag control unit 98820-9WD0A controls the protective devices. From the signals of the crash sensors, it determines within milliseconds the appropriate triggering of airbags and seatbelt pretensioners.

In addition, it checks the system without pause and displays faults via the airbag warning light in the instrument cluster.

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

Why does the control unit 98820-9WD0A fail?

The most common cause is crash data stored after an accident, even without an airbag being triggered. Usual diagnostic tools cannot erase it. Further causes are aged electronics, cold solder joints, moisture and corrosion, and voltage spikes.

As long as the data remains in the memory, the fault stays in the system. The other causes concern the electronics themselves and their connections.

Voltage spikes arise, for example, from a weak battery or from a jump start.

How can you tell that the 98820-9WD0A is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, and a fault message appears in the instrument cluster. In addition, the diagnostic tool cannot reach the control unit, and the fault memory cannot be cleared.

If this is the case, airbags and seatbelt pretensioners may not trigger in an emergency. Please have the condition checked promptly.
