Airbag control unit with part number 98820-9NG2A

What does the airbag control unit 98820-9NG2A do?

The airbag control unit 98820-9NG2A controls the restraint system (SRS) of Infiniti. It evaluates crash sensors, decides in an emergency within milliseconds on the triggering of airbags and seatbelt pretensioners, and monitors the system continuously.

It indicates faults via the airbag warning light. After an accident it stores crash data and locks itself; only the repair lifts the lock.

The decision is based on the signals the unit receives at the moment of impact, and on the electronics working reliably throughout the vehicle's service life.

Why does the control unit 98820-9NG2A fail?

The most common cause is stored crash data after an accident, even if no airbag has deployed. Further causes are ageing components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

Crash data cannot be erased with a normal diagnostic tool. Airbag24 removes it during the repair.

Electronics age, contacts are attacked by moisture, and voltage spikes, for example from a weak battery or jump-starting, can affect the unit.

How can you tell that the 98820-9NG2A is defective?

Typical signs are an airbag warning light in the instrument cluster that lights up permanently or intermittently, 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. In an emergency, the airbags and seatbelt pretensioners may then not deploy.

The warning light is one of the most important displays in the vehicle, as it shows the state of the restraint system directly in the driver's field of view.

A fault memory that cannot be emptied is a clear indication of a fault.
