Airbag control unit with part number 98820-JJ80A

What does the airbag control unit 98820-JJ80A do?

The airbag control unit 98820-JJ80A is responsible for the entire restraint system at Infiniti. It reads the crash sensors, determines the triggering of the airbags and seatbelt pretensioners in a collision, and monitors all components while the vehicle is in operation.

The results of this monitoring appear as a fault message via the airbag warning light. The unit works unobtrusively in the background.

After an accident, it stores crash data and then locks itself.

Why does the control unit 98820-JJ80A fail?

Most often, the cause is crash data stored after an accident, even if no airbag has deployed. Ordinary diagnostic tools cannot erase it. Other reasons include ageing components, cold solder joints, moisture in connectors and voltage spikes.

Crash data is a record of the event and is not visible on the vehicle at first glance. Airbag24 removes it during the repair of the 98820-JJ80A.

The other causes tend to act gradually. Electronics age, solder joints can go cold, and moisture attacks the contacts. Voltage spikes arise, for example, from a weak battery or when starting with an external power source.

How can you tell that the 98820-JJ80A is defective?

A defect in the 98820-JJ80A can be recognised by the airbag warning light, which stays on permanently or intermittently. In addition, fault messages appear in the instrument cluster, the diagnostic tool does not connect, and the fault memory cannot be cleared.

The warning light is a clear sign that something is wrong with the restraint system. In an emergency, airbags and seatbelt pretensioners may then not trigger, so an examination is important.

The message appears directly in the vehicle, so you will notice it without any tools. Respond to it promptly.
