Airbag control unit with part number 98820-1EE0B

What does the airbag control unit 98820-1EE0B do?

The airbag control unit 98820-1EE0B takes over control within the restraint system (SRS) of Nissan. It evaluates the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners trigger, and checks the system continuously. Faults appear at the airbag warning light.

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

The ongoing monitoring covers the connected components of the system and runs in the background.

Why does the control unit 98820-1EE0B fail?

The most common cause: crash data stored after an accident, even if no airbag has triggered. Other possible causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data cannot be removed with an ordinary diagnostic tool. Airbag24 removes it during the repair.

The other causes concern electronics and connections:

• components that have aged
• solder joints that have gone cold
• moisture or corrosion at plug connections
• voltage spikes, for example from a weak battery or jump start

How can you tell that the 98820-1EE0B is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, an error message appears in the instrument cluster, the diagnostic tool cannot reach the control unit, or the fault memory stays and cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then possibly not trigger.

The warning light is the signal you are most likely to notice in everyday life. It shows that the system has registered a fault and requires clarification.

A diagnostic tool that cannot establish a connection also points to a fault.

How does the repair of the 98820-1EE0B work?

The fault memory is read out first, then the battery is disconnected and only then the control unit is removed. Create the repair order online and send the well-packed device to Airbag24. Processing there usually takes 3–4 working days.

The protocol of the fault memory goes into the parcel. The sequence protects you during work on the vehicle.

At Airbag24 the device is first placed on the test bench. Defective components are then repaired, crash data is deleted and a function test is carried out, before your own device goes 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 98820-1EE0B get to Airbag24?

You send the device as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 sends it back by UPS.

Put the printed repair order into the parcel. Pack the control unit shockproof before it leaves.
