Airbag control unit with part number 98820-7FM0A

What does the airbag control unit 98820-7FM0A do?

The airbag control unit 98820-7FM0A is the central control unit of the restraint system (SRS) for Nissan. It evaluates the signals from the crash sensors and decides in the event of an emergency within milliseconds which airbags and seatbelt pretensioners are triggered.

In addition, it monitors the entire system continuously. It shows faults via the airbag warning light in the instrument cluster.

After an accident the control unit stores crash data and locks itself. This lock is only lifted by the repair.

Why does the control unit 98820-7FM0A fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Further triggers are aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes at the 98820-7FM0A.

Stored crash data cannot be erased with a normal diagnostic tool. This also applies when the airbags did not deploy at all.

The other causes tend to develop gradually. Electronic components age, solder joints can go cold, and moisture attacks plug connections. Voltage spikes arise, for example, with a weak battery or jump start and can damage the electronics.

How can you tell that the 98820-7FM0A is defective?

A defect shows up as the airbag warning light, which lights up permanently or intermittently, and as a fault message in the instrument cluster. In addition, the diagnostic tool cannot establish a connection to the control unit, and the fault memory cannot be cleared.

If the system is faulty, airbags and seatbelt pretensioners may possibly not deploy in an emergency. Therefore never ignore a lit warning light.

Even a warning light that lights up only briefly is a hint that you should have checked.
