Airbag control unit with part number 98820-6UA0C

What does the airbag control unit 98820-6UA0C do?

The unit is the SRS control unit of Nissan and decides in a crash which airbags and seatbelt pretensioners are triggered. To do this, it continuously analyses the signals from the crash sensors and monitors the entire system.

If it detects a fault, it indicates this via the airbag warning light.

After a crash, it stores crash data and locks itself. The consequences of this lock for diagnosis and repair are described in the following sections.

Why does the control unit 98820-6UA0C fail?

The most common cause is crash data stored after a crash, even if no airbag has triggered. At the same time, electronic components can age and solder joints can go cold.

A normal diagnostic tool cannot reach this data. Moisture and corrosion at plug connections also lead to faults.

A voltage dip, for example from a weak battery, or a jump start can also affect the electronics. For this reason, it is worth checking the fault memory as soon as the system behaves abnormally.

How can you tell that the 98820-6UA0C is defective?

The airbag warning light in the instrument cluster stays on permanently or lights up only intermittently. At the same time, a fault message appears, the diagnostic tool gets no connection to the control unit, and the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then not trigger.

Typical signs are:

• airbag warning light that stays on permanently or lights up intermittently
• fault message in the instrument cluster
• no connection between diagnostic tool and control unit
• fault memory that cannot be cleared

The warning light indicates the defect. If it lights up, have the fault memory read out.

Compare the part number on the label of the removed unit with this page. The comparison only confirms that you have the right unit. Have the fault memory read out beforehand, because only this record shows whether the control unit itself is defective or whether a plug or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 98820-6UD0B, 98820-6UM0B, 98820-6UT0A, 98820-6UT0B, 98820-9PV0A, 98820-9PV0C.

How does the repair of the 98820-6UA0C work?

Processing at Airbag24 usually takes 3–4 working days. There the unit is examined on the test bench, defective components are replaced, stored crash data is erased and a function test is carried out.

Before sending, you carry out a few steps yourself: have the fault memory read out and enclose the readout log. Then disconnect the battery, remove the control unit and create a repair order online.

This sequence is for safety reasons and is therefore binding. After the function test, 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 98820-6UA0C get to Airbag24?

You book a UPS collection for an extra charge, or alternatively send the unit as a parcel. The return after the repair is also made by UPS.

The printed repair order goes in the parcel, and the unit is packed shock-proof.
