Airbag control unit with part number 98820-1EK0A

What does the airbag control unit 98820-1EK0A do?

The airbag control unit 98820-1EK0A belongs to the restraint system (SRS) of Nissan. It reads the crash sensors, decides in an accident within milliseconds whether airbags and seatbelt pretensioners are triggered, and keeps the system under control during operation.

In everyday use the unit works unnoticed in the background. It checks the circuits and records deviations in the fault memory.

After an accident it stores crash data and locks itself.

Why does the control unit 98820-1EK0A fail?

Most common cause: crash data stored after an accident, even if no airbag was triggered. A normal diagnostic tool cannot erase it. Added to this are aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example with a weak battery or a jump start.

Airbag24 erases the crash data during the repair. The other causes develop gradually, because moisture and heat act on circuit boards and contacts over years.

Voltage spikes act on the electronics briefly and can leave faults in the memory.

How can you tell that the 98820-1EK0A is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and a fault message appears. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

Typical signs at a glance:

• Airbag warning light lights up permanently or intermittently
• Fault message in the instrument cluster
• No connection of the diagnostic tool to the control unit
• Fault memory that cannot be cleared

Anyone who notices these signs should have the fault memory read out promptly, because only then is it clear what the cause is.

For the same vehicles, we also repair control units with the part numbers 25348 1A33B, 98820 1EJ1A, 98820-1EA0A, 98820-1ER0A, K8820-1EA0A, K8820-1EJ0A.

How does the repair of the 98820-1EK0A work?

Before anything else, have the fault memory read out and prepare the log. Before removal, disconnect the battery; then remove the control unit. Afterwards create a repair order online and send in the packed unit.

Airbag24 checks the unit on the test bench, repairs defective components and erases stored crash data. After that a function test follows, and then your own unit goes back. The processing takes 3–4 working days as a rule.

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 98820-1EK0A get to Airbag24?

Either you send the unit yourself as a parcel, or you book a UPS collection for an extra charge. After the repair, the unit comes back to you by UPS.

The printed repair order goes into the parcel, and the control unit must be packed shockproof.
