Airbag control unit with part number 98820-1VX0A

What does the airbag control unit 98820-1VX0A do?

The control unit 98820-1VX0A is the central control unit of the airbag system of Nissan. It processes the measured values from the crash sensors, selects within milliseconds in a crash which airbags and seatbelt pretensioners to trigger, and monitors the system constantly. Detected faults are shown via the airbag warning light.

Besides triggering, it checks sensors, wiring and firing circuits. After an accident it stores crash data and locks itself.

Why does the control unit 98820-1VX0A fail?

Crash data from an accident, even without a triggered airbag, is the most common cause. This data cannot be removed with an ordinary diagnostic tool. In addition, aged components, cold solder joints, moisture, corrosion and voltage spikes can cause the failure.

Aged electronics and cold solder joints lead to loose contacts during operation. Moisture and corrosion attack the plug connections.

Voltage spikes, for example from a weak battery or a jump start, can damage components.

How can you tell that the 98820-1VX0A is defective?

A defect shows up as the airbag warning light in the instrument cluster lighting up permanently or only intermittently, or as a fault message in the instrument cluster. A diagnostic tool without a connection to the control unit and a fault memory that cannot be emptied also point to it.

In an emergency, airbags and seatbelt pretensioners may fail to deploy as long as the fault persists. Therefore have the system checked promptly.

The signs do not all have to appear at the same time.
