Airbag control unit with part number 98820-6HA0B

What does the airbag control unit 98820-6HA0B do?

The airbag control unit 98820-6HA0B coordinates the triggering of airbags and seatbelt pretensioners in the SRS of Infiniti. To do so, it evaluates the crash sensors and decides within milliseconds in the event of an accident.

Between events it monitors the system. It shows detected faults via the airbag warning light, and after an accident it stores crash data and locks itself.

Why does the control unit 98820-6HA0B fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Further causes are aged components, cold solder joints, moisture and corrosion on connectors, and voltage spikes.

A weak battery or a jump start can cause such voltage spikes. The fault memory determines the exact cause.

How can you tell that the 98820-6HA0B is defective?

A defect shows up as the airbag warning light in the instrument cluster staying on permanently or intermittently. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

Typical signs also include:

• error message in the instrument cluster
• no connection between the diagnostic tool and the control unit
• fault memory that cannot be cleared

If you notice these signs, have the system checked.
