Airbag control unit with part number 98820-7FH1A

What does the airbag control unit 98820-7FH1A do?

The airbag control unit 98820-7FH1A coordinates the restraint system (SRS) of Nissan. It evaluates the signals from the crash sensors and determines which airbags and seatbelt pretensioners are triggered in an accident within milliseconds.

The electronics also check continuously whether all connected components are working. If they detect a fault, they report it via the airbag warning light in the instrument cluster.

After an accident, the control unit secures crash data and is locked afterwards.

Why does the control unit 98820-7FH1A fail?

The most common cause of a failure of the 98820-7FH1A is crash data from an earlier accident, even if no airbag was triggered. A normal diagnostic tool cannot remove this data. Aged components, cold solder joints, corrosion at plug connectors and voltage spikes are also possible causes.

Electronic components age like all other components, and their solder joints can weaken over time.

Moisture and corrosion at the plugs, as well as voltage spikes, for example from a weak battery or jump-starting, are also among the possible causes. Airbag24 erases the crash data during the repair; the test shows which of the other causes applies.

How can you tell that the 98820-7FH1A is defective?

The airbag warning light in the instrument cluster is the first sign: it lights up on the 98820-7FH1A either permanently or intermittently. A fault message in the instrument cluster may accompany it, or the diagnostic tool gets no connection to the control unit, or the fault memory cannot be cleared. Then airbags and seatbelt pretensioners may not trigger in an emergency.

The light thus shows the defect clearly. If it stays on, a check of the system is advisable.

A fault memory that cannot be reset also points to an existing fault. Take such signs seriously and have the fault read out.
