Airbag control unit with part number 98820-1VB1A

What does the airbag control unit 98820-1VB1A do?

The airbag control unit 98820-1VB1A is the central control unit of the restraint system (SRS) for Infiniti. It evaluates the crash sensors, decides in an accident on the triggering of airbags and seatbelt pretensioners, and monitors the system continuously.

It reports faults via the airbag warning light in the instrument cluster, and they are also recorded in the fault memory.

After an accident the unit stores crash data and locks itself.

Why does the control unit 98820-1VB1A fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. A usual diagnostic tool cannot remove it.

Aged electronic components and cold solder joints can also occur. Moisture and corrosion at plug connections can disturb the contact, and voltage spikes, for example from a weak battery or a jump start, stress the unit.

The exact cause only becomes clear during the test on the test bench.

How can you tell that the 98820-1VB1A is defective?

A defect is indicated by an airbag warning light in the instrument cluster that lights up permanently or intermittently, an error message there, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

The warning light in the instrument cluster is the clearest sign. It should not be ignored, even if it only lights up now and then.

In an emergency, airbags and seatbelt pretensioners may not deploy.
