Leapmotor B10 airbag control unit repair⁽¹⁾

What should I pay attention to with Leapmotor B10 airbag control units?

The airbag control unit in the Leapmotor B10 evaluates the signals from the crash sensors, triggers the airbags and seat belt pretensioners, and reports faults in the system via the airbag warning light. After an accident, it stores crash data and locks itself. Airbag24 repairs your own control unit once it has been sent in.

A defective control unit can impair the function of the entire restraint system. The airbag warning light then indicates that something is wrong in the system and should not be ignored.

The airbag system is safety-relevant. Work on it belongs in the hands of a specialist workshop and is not a do-it-yourself job.

Which Leapmotor B10 generations are there?

The Leapmotor B10 has been built since 2025, and production is still ongoing. It is listed as the B10 series.

• B10 (since 2025) – current series, still in production.

Within the series, equipment and control unit variants can differ by year of manufacture. That is why the year of manufacture is part of every enquiry, so that the right unit can be identified.

How do I identify my Leapmotor B10 airbag control unit?

The part number on the label of the control unit determines the exact version. The model year and equipment of the vehicle should also be known, as they confirm the assignment.

The control unit carries a label with the part number. Comparing this number with the model year and the vehicle identification number (VIN) allows the unit to be assigned clearly. Without this comparison, it is not possible to say with certainty which version is fitted.

The fault memory may show fault codes. One example is U0151, which means that communication with the airbag control unit (restraint system module) has been lost. A single fault code, however, does not prove a defect in the control unit; the cause is determined by a test in the workshop.

What airbag equipment does the Leapmotor B10 have?

The Leapmotor B10 comes with front, side and head airbags as standard, plus a centre airbag on the driver's side. According to the 2025 NCAP safety assessment, no knee airbags are fitted.

The front airbags for driver and front passenger are standard. Side airbags for chest and pelvis are fitted on both front seats, and head airbags at the front and rear. These details refer to the assessed variant; equipment may differ depending on the trim level.

The control unit coordinates the triggering of all modules, so a defect affects the entire restraint system rather than a single airbag.

The route to repair: have the fault memory read out by a specialist workshop. The battery is disconnected before removal, and removal of the control unit should also be carried out by a specialist workshop. You then create a repair order online and send in the control unit. Processing usually takes 3–4 working days (checking, repair, testing).

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