Airbag control unit with part number 98820-6RR0E

What does the airbag control unit 98820-6RR0E do?

The airbag control unit 98820-6RR0E coordinates the SRS system of Nissan. From the signals of the crash sensors it calculates whether an accident requires a triggering, and then controls airbags and seatbelt pretensioners. During operation it continuously checks all connected components and reports faults via the airbag warning light.

Evaluation of the sensors happens practically in real time, because in a crash every moment counts. The control unit works independently of the driver and runs as soon as the ignition is switched on.

After an accident the unit stores crash data and then locks itself. This lock applies to the entire control unit and is not limited to individual functions.

The function of the unit is easiest to understand as a guardian of the system, one that triggers nothing as long as no triggering is required.

Why does the control unit 98820-6RR0E fail?

Crash data is the most common cause: it remains in the memory after an accident, even if no airbag has triggered, and a normal diagnostic tool cannot erase it. Other causes include ageing electronic components, cold solder joints, moisture and corrosion at plug connections, as well as voltage spikes, for example from a weak battery or a jump start.

Crash data belongs to the cases in which the control unit itself may be fine and still show a fault. Airbag24 removes the data from the memory completely during repair.

The remaining causes concern the electronics and the connections. Ageing components lose reliability over time, cold solder joints arise during manufacturing, and moisture attacks plug connections. Voltage spikes arise when the on-board voltage briefly drops or rises too high.

Such causes can only be narrowed down by a test, not by looking at the unit alone.

How can you tell that the 98820-6RR0E 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 gets no connection to the control unit, and the fault memory cannot be cleared. In the event of a defect, airbags and seatbelt pretensioners may not be able to trigger in an emergency.

The airbag warning light in the instrument cluster lights up as soon as the system registers a fault. Pay attention to whether it burns continuously or only lights up intermittently, because both are signs you should not ignore.

An error message may also appear in the instrument cluster. If the diagnostic tool does not connect to the control unit, or the fault memory cannot be reset, that too points to a problem in the system.

Which vehicles is the 98820-6RR0E fitted in?

The control unit 98820-6RR0E is used for Nissan in these vehicles: Nissan Rogue T32 (2013-2020).

The overview shows which vehicles belong to this part number:

• Nissan Rogue T32 (2013-2020)

Compare the part number on the label of the removed unit with this page. That way you can see that you have the correct unit in front of you. Have the fault memory read out beforehand, because only the log shows whether the control unit itself or a plug or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 98820 JM100, 98820-1VK0A, 98820-1VL0A, 98820-4BS0A, 98820-7FL9E, 98820-9FM0A.

How does the repair of the 98820-6RR0E work?

First have the fault memory read out and attach the log to the unit. Then disconnect the battery and remove the control unit. Finally, create a repair order online and pack the unit carefully for sending.

The order is fixed for safety reasons. Therefore keep exactly to this sequence.

At Airbag24 the unit is first examined on the test bench. Defective components are replaced, the stored crash data is deleted, and a function test is then carried out. Processing at Airbag24 usually takes 3–4 working days, after which your own unit is 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 98820-6RR0E get to Airbag24?

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

Put the printed repair order into the parcel, and pack the control unit shockproof.
