Nissan NV400 airbag control unit repair⁽¹⁾

What should be noted about Nissan NV400 airbag control units?

The airbag control unit of the Nissan NV400 evaluates the crash sensors, triggers the airbags and seatbelt pretensioners, and monitors the entire airbag system. If it detects a fault, the airbag warning light comes on in the instrument cluster. Airbag24 repairs the control unit you send in.

After an accident involving airbag deployment, the control unit stores the crash data and locks itself. Battery problems, voltage spikes, moisture on connectors or communication faults on the CAN bus can also trigger a fault without any collision.

Airbag systems are safety-relevant. Work on them should be carried out only by a specialist workshop. Airbag24 checks the unit at its workshop in Berlin, repairs it and deletes the crash data.

Which Nissan NV400 generations are there?

The Nissan NV400 is listed in the X62 model series, which was built from 2010 to 2024. The exact version of the control unit follows from its part number, not from the model series alone.

The X62 series is a van. Within its production period, equipment and control unit variants can differ depending on the model year.

• X62 (2010–2024) – model series of the Nissan NV400, built from 2010 to 2024

How do I identify my Nissan NV400 airbag control unit?

The part number on the label of the control unit determines the exact version. In addition, check the model year and equipment of your vehicle.

The following part number is known for the Nissan NV400. It does not claim to be complete:

• 98820EY21B

Examples of fault codes are B1100 (fault in the airbag control unit), B1209 (frontal collision detected, crash data stored in the control unit), B1210 (side collision detected, crash data stored in the control unit) and U1000 (CAN communication line disturbed). A single code does not prove a defect in the control unit; a diagnosis at a specialist workshop establishes the cause.

What airbag equipment does the Nissan NV400 have?

According to available vehicle tests, a driver airbag is standard equipment on the Nissan NV400. Whether a passenger airbag and further airbags, such as side, head or knee airbags, are fitted depends on the model year and specification.

No clear information is available on side, head or knee airbags for the Nissan NV400. The actual equipment of your vehicle follows from the vehicle documents or can be confirmed by a specialist workshop.

The route to repair: have the fault memory read out, disconnect the battery and have the control unit removed by a specialist workshop. Then create a repair order online and send in the control unit. Processing usually takes 3–4 working days (checking, repairing, testing).

The repaired control unit returns with all vehicle data and is ready for use immediately after reinstallation — no coding or programming is necessary.
