Nissan NV300 airbag control unit repair⁽¹⁾

What should I pay attention to with Nissan NV300 airbag control units?

The airbag control unit in the Nissan NV300 evaluates the crash sensors, triggers the airbags and seat belt pretensioners, and monitors the entire system. If it detects a fault, the airbag warning light comes on. After an accident, the control unit stores crash data and locks itself.

Airbag24 repairs the control unit you send in by post. During the repair, the crash data is erased and the unit is then tested. A defective airbag control unit affects the function of the entire airbag system, so the cause should be clarified promptly.

If the airbag warning light stays on, the system may work in a limited way or fail completely in an emergency. Do not leave the fault unattended; have it checked by a specialist workshop. Airbag systems are safety-relevant, so work on them should be left to professionals.

Which Nissan NV300 generations are there?

The Nissan NV300 was built in the X82 series from 2016 to 2021. The series determines which airbag control units come into consideration, so model year and part number should always be checked together.

The NV300 is a mid-sized van. In Europe it was available from November 2016 as a panel van, crew van and passenger combi.

The list shows the series to which the information on this page refers:

• X82 (2016–2021): series of the Nissan NV300 as panel van, crew van and combi

How do I identify my Nissan NV300 airbag control unit?

The part number on the label of the control unit determines the exact version. Together with the year of manufacture, the vehicle identification number (VIN) and the equipment of your vehicle, the matching unit can be clearly assigned.

Known part number for the Nissan NV300 in series X82, without claim to completeness:

• 985106142R

Examples of fault codes that can occur with the airbag control unit are 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). However, a fault code alone does not prove a defect. Only reading out and testing the unit shows whether it is affected.

What airbag equipment does the Nissan NV300 have?

According to Nissan's manufacturer information at market launch, the NV300 has front airbags for driver and front passenger as well as lateral curtain airbags. Vehicles with an individual front passenger seat also receive a thorax airbag.

The airbags are controlled by the airbag control unit, and the front seat belt pretensioners are linked to the front airbags. Which equipment is actually fitted to your vehicle depends on the version and can be clarified using the vehicle identification number and the part number.

This is how the repair works: have the fault memory read out at a workshop. The workshop then disconnects the battery and removes the control unit. You then create a repair order online and send the removed control unit well packed to Airbag24. Processing usually takes 3–4 working days and includes checking, repairing and testing.

The repaired control unit returns with all vehicle data and is ready for use immediately after reinstallation — coding or programming is not necessary.
