Airbag control unit with part number 98820-6AT0A

What does the airbag control unit 98820-6AT0A do?

The control unit 98820-6AT0A controls the SRS restraint system of Infiniti. It processes the measured values from the crash sensors, decides in an accident within fractions of a second which airbags and seatbelt pretensioners are triggered, and checks the system continuously. If it detects a fault, it reports it via the airbag warning light.

The electronics work in the background without you having to operate them. Their task is to prepare triggering correctly.

After an accident the unit stores crash data and locks itself.

Why does the control unit 98820-6AT0A fail?

The most common cause: crash data from an earlier accident, even if no airbag fired. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or a jump start, also come into consideration.

This crash data stays in memory until Airbag24 removes it during the repair. A common reading tool does not clear it from memory.

Aged components and cold solder joints can hardly be judged from the outside. Moisture and corrosion mainly attack the connectors.

Only examining the unit shows which of these points applies.

How can you tell that the 98820-6AT0A is defective?

A first sign is the airbag warning light in the instrument cluster staying on permanently or intermittently. Added to this are a fault message in the instrument cluster, a diagnostic tool that cannot establish a connection to the control unit, and a fault memory that cannot be cleared.

As long as these signs persist, airbags and seatbelt pretensioners may fail to deploy in an emergency. You should therefore not ignore the warning.

An inspection at a specialist workshop will clarify which component is affected.

Compare the number on the label of the removed unit with this page. That only shows you whether it is the right unit. Have the fault memory read out beforehand, because the log shows whether the control unit is faulty or whether a connector or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 285012561, 988206AE0A.

How does the repair of the 98820-6AT0A work?

Have the fault memory read out and enclose the log, then disconnect the battery and only after that remove the control unit. Afterwards you create the repair order online and send in the unit well packed. At Airbag24, inspection, repair and function test together usually take 3–4 working days.

Airbag24 checks the unit on the test bench and replaces faulty components. The stored crash data is then erased and a function test is carried out before your own unit is sent back to you.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 98820-6AT0A get to Airbag24?

You send the unit to Airbag24 as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 returns it by UPS. The printed repair order belongs in the parcel.

The unit should be packed shock-resistant so that it does not suffer damage on the way.
