Airbag control unit with part number 98820-6WJ0A

What does the airbag control unit 98820-6WJ0A do?

The airbag control unit 98820-6WJ0A controls the SRS restraint system on Infiniti. It evaluates the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners are triggered.

It checks the components continuously, and faults appear on the airbag warning light in the instrument cluster. If it has recorded an accident, it locks itself after storing the crash data.

In this way, it connects the sensors with the triggers.

Why does the control unit 98820-6WJ0A fail?

On the 98820-6WJ0A, crash data stored after an accident is the most common cause, even if no airbag has fired. Other possible causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A standard diagnostic tool cannot remove the crash data. Airbag24 carries out this step during the repair.

Voltage spikes arise, for example, from weak batteries or a jump start.

How can you tell that the 98820-6WJ0A is defective?

The airbag warning light in the instrument cluster lights up on the 98820-6WJ0A either permanently or intermittently. Also present are an error message in the instrument cluster, a diagnostic tool without connection, and a fault memory that cannot be cleared.

Signs like these mean that airbags and seatbelt pretensioners may not trigger in an emergency.

The warning light is driven by the control unit itself, which makes it a clear sign.
