Airbag control unit with part number 98820-6RF0E

What does the airbag control unit 98820-6RF0E do?

The airbag control unit 98820-6RF0E is the central control unit of the restraint system (SRS) for Nissan. It evaluates the signals from the crash sensors, decides in an accident within the shortest possible time which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. If it detects a fault, it indicates this via the airbag warning light.

During operation, the unit continuously checks the connections to the sensors, airbags and seatbelt pretensioners. It stores irregularities in the fault memory so that a workshop can look for the cause in a targeted way. It works in the background without you having to operate anything.

After an accident, the control unit stores crash data and locks itself. This applies even if no airbag was triggered in the accident.

Why does the control unit 98820-6RF0E fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot delete it. 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, are also possible causes.

Crash data arise even after accidents in which no airbag deploys. They remain in the memory of the unit until they are deliberately deleted, which is exactly why a fault cannot be rectified with an ordinary tool.

The other causes lie in the electronics themselves. Aged components and cold solder joints can cause faults that occur only intermittently and are therefore difficult to trace.

Moisture and corrosion impair the contact at plug connections. Voltage spikes, for example from a weak battery or when a jump start is connected, additionally stress the electronics.

How can you tell that the 98820-6RF0E is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, and a fault message may appear in addition. Furthermore, the diagnostic tool cannot establish a connection to the control unit, or the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The warning light is the most important signal the vehicle gives you. It shows that the system has detected a fault, whether or not you notice anything in everyday driving.

Even if the light only flickers now and then, the finding must be taken seriously. A fault that occurs only intermittently is still stored in the fault memory and is worth an inspection.

Which vehicles is the 98820-6RF0E fitted in?

Compare the part number on the label of the removed unit with this page. This way you can make sure that it is the right unit. Also have the fault memory read out, because only that result shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 988205HA0A.

How does the repair of the 98820-6RF0E work?

You first read out the fault memory and enclose the log. Then you disconnect the battery, remove the control unit, create a repair order online and send the unit in, well packed. Airbag24 tests it on the test bench, repairs defective components, deletes stored crash data and carries out a function test; processing usually takes 3–4 working days.

The sequence serves your safety and is therefore binding. The control unit may be removed only after the fault memory has been secured and the battery has been disconnected.

After the function test, your own unit is returned to you. The period of 3–4 working days refers only to the inspection, repair and testing at Airbag24, not to your steps or to shipping.

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 98820-6RF0E get to Airbag24?

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

Enclose the printed repair order in the parcel and pack the control unit securely against shocks so that it arrives at Airbag24 undamaged.
