Airbag control unit with part number 98820-5RE0B

What does the airbag control unit 98820-5RE0B do?

As the central unit of the restraint system (SRS) at Nissan, the airbag control unit 98820-5RE0B works. It checks the sensor signals, decides in the event of an accident on airbags and seatbelt pretensioners, and reports faults via the airbag warning light.

During normal operation, monitoring continues unobtrusively. In an emergency the unit must react immediately, so it works continuously.

If an accident occurs, the control unit stores crash data and locks itself. This section says only that; the following sections explain causes and sequence.

Why does the control unit 98820-5RE0B fail?

The most common cause is stored crash data from an accident, even without airbag deployment. A normal diagnostic tool cannot delete it. Other possible causes include ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

The crash data remains in the unit until it is removed during repair, and Airbag24 takes on this step.

The remaining causes concern the general condition of the electronics. Components age, solder joints can be cold, and moisture or corrosion weakens plug connections.

Voltage spikes arise, for example, with a weak battery or when jump-starting. Which of these causes is present is shown only by the test.

How can you tell that the 98820-5RE0B is defective?

The airbag warning light in the instrument cluster indicates the fault by lighting up intermittently or permanently. In addition, there are fault messages in the instrument cluster, no connection for the diagnostic tool, and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may therefore fail to deploy.

This light is the most important hint the system gives. Take it seriously, even if the vehicle otherwise drives normally.

Only reading the fault memory clarifies the cause. Have it done promptly.

Comparing the part number on the label with this page ensures that you have the right unit. Whether the control unit itself is defective, or a plug or cable is behind the fault, is shown only by the fault memory, which you should have read beforehand.

For the same vehicles, we also repair control units with the part numbers 98820-5RX0B.

How does the repair of the 98820-5RE0B work?

First comes reading the fault memory, together with the enclosed log. Only then do you disconnect the battery and remove the control unit, before creating a repair order online. At Airbag24, processing usually takes 3–4 working days.

Airbag24 determines the process through testing and repair: the unit is examined on the test bench, defective components are repaired and stored crash data is deleted. A function test follows before your own unit is sent back.

The sequence on the vehicle is binding for safety reasons.

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 98820-5RE0B get to Airbag24?

You send the unit packed as a parcel, or book a UPS collection for an extra charge. After the repair, Airbag24 returns it to you by UPS.

Include the printed repair order and pack the unit shock-proof.
