Airbag control unit with part number 98820-1VZ0A

What does the airbag control unit 98820-1VZ0A do?

The airbag control unit 98820-1VZ0A is the central control unit of the restraint system (SRS) for Infiniti. It evaluates the signals from the crash sensors, determines in a crash within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident it stores crash data and locks itself.

If the system reports a fault, the control unit shows it via the airbag warning light in the instrument cluster.

Without a working control unit, neither an airbag nor a seatbelt pretensioner can trigger in a targeted way in an emergency, even if these components are undamaged.

Why does the control unit 98820-1VZ0A fail?

The most common cause is crash data stored after an accident, even when no airbag has deployed; a diagnostic tool cannot erase it. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting, can also be causes.

Crash data is therefore stored even if no airbag was triggered. As a result, the link to the incident is not always obvious to the driver.

Aged components and corrosion act over time, whereas voltage spikes can take effect quickly. Which cause is present in your unit is determined only by the test.

How can you tell that the 98820-1VZ0A is defective?

A defect shows first at the warning light in the instrument cluster, which stays on permanently or intermittently. In addition there is a fault message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be emptied.

During such a defect, airbags and seatbelt pretensioners may possibly fail to trigger in an emergency. That is why the warning should not be ignored.

The light shows the defect directly, so please have the warning checked promptly.

On the one hand, it is worth comparing the part number on the label of the removed unit with this page; it only ensures that it is the right unit. On the other hand, have the fault memory read out beforehand, because only that shows whether the control unit is defective or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 98820-1VZ0B, 98820JL03B.

How does the repair of the 98820-1VZ0A work?

First have the fault memory read out and attach the log to the unit, then disconnect the battery and only afterwards remove the control unit. Then create a repair order online and send the unit in well packed. The processing at Airbag24 usually takes 3–4 working days.

Airbag24 tests the unit on the test bench, repairs defective components, erases stored crash data and carries out a function test. Afterwards your own unit returns to you.

Only the testing, repairing and function testing at Airbag24 require this time. Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
