Airbag control unit with part number 98820 EG000

What does the airbag control unit 98820 EG000 do?

In the Nissan vehicle, the airbag control unit 98820 EG000 takes over control of the SRS. It evaluates the crash sensors, decides in a crash within milliseconds whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident, it stores crash data and locks itself.

If the system detects a fault, it reports it to the driver via the airbag warning light.

Airbags and seatbelt pretensioners work together through this control unit, so a fault in it affects the entire system.

Why does the control unit 98820 EG000 fail?

With the 98820 EG000, the most common cause after an accident is stored crash data, even if no airbag has deployed, and a standard diagnostic tool cannot erase it. Other possible causes include aged components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes. Airbag24 erases crash data during the repair.

Crash data are records the control unit keeps of an accident. They remain in the memory even if no airbag has deployed during the event.

Aged electronics and cold solder joints can impair function. Moisture and corrosion at plug connections additionally disturb the contact.

Voltage spikes arise, for example, from a weak battery or a jump start, and they stress the components.

How can you tell that the 98820 EG000 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently as soon as there is a defect in the 98820 EG000. A fault message in the instrument cluster and a fault memory that cannot be cleared are typical signs. In an emergency, airbags and seatbelt pretensioners may fail to deploy.

The signs at a glance:

• airbag warning light on permanently or intermittently
• fault message in the instrument cluster
• diagnostic tool without connection to the control unit
• fault memory cannot be cleared

Such warnings deserve a prompt check, because they affect the restraint system.
