Airbag control unit with part number 98820-6AD0A

What does the airbag control unit 98820-6AD0A do?

The airbag control unit 98820-6AD0A controls the SRS in vehicles from Infiniti. It checks the crash sensors, determines in an accident which airbags and seatbelt pretensioners trigger, and monitors the system continuously. After an accident it stores crash data and locks itself.

Monitoring runs in the background, and every detected fault is reported via the airbag warning light.

As for the lock after an accident: it ends only with the repair at Airbag24.

Why does the control unit 98820-6AD0A fail?

Crash data that remains in the memory after an accident is the most common cause, even if no airbag has been triggered. A normal diagnostic tool cannot erase it. Aged components, cold solder joints, moisture and voltage spikes also play a role.

The crash data stays in the unit as long as nobody removes it, and Airbag24 removes it during the repair.

Aged components and cold solder joints lead to loose contacts.

Moisture, corrosion at plugs and voltage spikes from a weak battery or a jump start have a similar effect.

How can you tell that the 98820-6AD0A is defective?

Typical signs are the airbag warning light, which lights up permanently or intermittently, an error message in the instrument cluster, a missing connection to the diagnostic tool, and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

• airbag warning light stays on
• warning message appears in the instrument cluster
• reader cannot reach the control unit
• fault memory remains after an attempt to clear it

These signs point to a fault. Do not leave the finding unattended.
