Airbag control unit with part number 98820-6WA0A

What does the airbag control unit 98820-6WA0A do?

The airbag control unit 98820-6WA0A is the control unit of the SRS system for Infiniti. It continuously checks the sensors, decides in a crash whether airbags and seatbelt pretensioners are triggered, and reports faults via the airbag warning light.

The crash sensor signals are evaluated within a fraction of a second, controlled by the unit itself.

After a crash, it stores crash data and locks itself.

Why does the control unit 98820-6WA0A fail?

The most common reason for the 98820-6WA0A to fail is crash data that is present even when no airbag has deployed. Diagnostic tools cannot remove it. Other causes include aged components, cold solder joints, moisture, corrosion and voltage spikes.

The data arises within the unit itself and remains stored there.

Aged components and cold solder joints impair signal transmission, while moisture and corrosion attack the plug connections.

Voltage spikes from weak batteries or jump-starting can strain the electronics.

How can you tell that the 98820-6WA0A is defective?

A defect on the 98820-6WA0A is indicated by the airbag warning light in the instrument cluster, which lights up permanently or intermittently. A fault message or a fault memory that cannot be erased also point to it. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

Typical signs:

• Airbag warning light permanently or intermittently on
• Fault message in the instrument cluster
• Diagnostic tool does not connect to the control unit
• Fault memory cannot be erased

The warning light shows the fault, so you do not have to wait for an inspection to see it.
