Airbag control unit with part number 98820-BF10A

What does the airbag control unit 98820-BF10A do?

The airbag control unit 98820-BF10A forms the central control unit of the restraint system (SRS) of Nissan. It evaluates the signals from the crash sensors and decides in an accident, within a few milliseconds, which airbags and seatbelt pretensioners are triggered.

At the same time, it monitors the system constantly and shows faults via the airbag warning light. This monitoring requires no action from you.

After an accident, it stores crash data and locks itself.

Why does the control unit 98820-BF10A fail?

Most often the cause is crash data stored in the unit after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase this data. Further causes on the 98820-BF10A are aged electronic components, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes.

Voltage spikes arise, for example, from a weak battery or a jump start. Such events affect the electronics and can trigger faults in the system.

Whether any of these causes is actually present is only clarified by examining the unit. Looking at the fault memory is worthwhile beforehand.

How can you tell that the 98820-BF10A is defective?

A defect in the 98820-BF10A shows itself through the airbag warning light in the instrument cluster, which lights up permanently or intermittently. Further signs are a fault message in the instrument cluster, no connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared.

• The airbag warning light is on permanently.
• The airbag warning light is on intermittently.
• A fault message appears in the instrument cluster.
• The diagnostic tool gets no connection to the control unit.
• The fault memory cannot be cleared.

While such a fault persists, the airbags and seatbelt pretensioners may not be able to deploy in an emergency.
