Airbag control unit with part number 98820 9H600

What does the airbag control unit 98820 9H600 do?

The airbag control unit 98820 9H600 is the control unit of the restraint system of Nissan. It processes the signals of the crash sensors, determines the triggering of airbags and seatbelt pretensioners within milliseconds in an impact, and monitors the system continuously. It shows faults via the airbag warning light in the instrument cluster.

Monitoring runs throughout operation. The unit checks sensors, wiring and triggering circuits, and stores any faults it finds in the fault memory.

After an accident it writes crash data and locks itself. Therefore have the fault memory checked for every warning, rather than ignoring the light.

Why does the control unit 98820 9H600 fail?

The most common cause is crash data from an accident, which is stored even if no airbag has fired. Aged components, cold solder joints, moisture and corrosion at plugs, and voltage spikes, for example from a weak battery or a jump-start, can also play a part.

An ordinary diagnostic tool cannot remove crash data. Airbag24 erases it during the repair. The other causes at a glance:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connectors
• voltage spikes, for example from a weak battery or jump-starting

How can you tell that the 98820 9H600 is defective?

You can recognise a defect when the airbag warning light stays on permanently or intermittently, when an error message appears in the instrument cluster, when the diagnostic tool cannot establish a connection to the control unit, or when the fault memory cannot be cleared. Airbags and seatbelt pretensioners may then fail to deploy in an emergency.

The warning light in the instrument cluster reports the fault as soon as the control unit detects it, and it calls for an investigation. Subjective driving impressions play no role here, because the display is what counts.

If there is no connection to the diagnostic tool, or if an entry in the fault memory cannot be removed, you should also have the case investigated.

For the same vehicles, we also repair control units with the part numbers 41650EQ070, 988208H40C, 98820JH43A, A68-000U06.

How does the repair of the 98820 9H600 work?

The fault memory is read out first, and the log goes into the parcel later. Then disconnect the battery and remove the control unit, and create the repair order online afterwards. Processing at Airbag24, meaning checking, repairing and testing, takes 3–4 working days as a rule.

At ours, the unit goes onto the test bench. Defective components are repaired or replaced, the crash data is erased and a function test is run. Your own control unit is then returned 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 9H600 get to Airbag24?

You send the control unit in as a parcel, or you use a UPS collection for an extra charge. After the repair, UPS brings the unit back to you.
