Leapmotor B03X airbag control unit repair⁽¹⁾

What should be considered for Leapmotor B03X airbag control units?

The airbag control unit in the Leapmotor B03X evaluates the crash sensors, triggers the airbags and belt tensioners, monitors the system and reports faults via the airbag warning light. After an accident, it stores crash data and locks itself.

A defective control unit impairs the function of the entire airbag system. For this reason, all work on the airbag system belongs in the hands of a specialist workshop; you should not work on it yourself.

Airbag24 repairs the customer's own control unit that is sent in. This includes erasing the crash data after an accident and checking for faults. Whether a unit that has been sent in can be repaired is shown by the check in our workshop.

Which Leapmotor B03X generations are there?

Our overview lists the Leapmotor B03X as a single model series. It has been built since 2026 and is also available in Europe.

The B03X is an electric SUV from the Leapmotor brand. The model series is listed here with its production period:

• B03X (since 2026) – current model series, available in Europe since 2026

Within the model series there are different equipment lines. You can tell whether your vehicle belongs to this series from the vehicle identification number (VIN) and the year of manufacture.

How do I identify my Leapmotor B03X airbag control unit?

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

The label on the control unit shows the part number. It is the most important reference point when it comes to repairing the Leapmotor B03X airbag control unit.

A fault code alone does not prove a defect. Code U0151, for example, means that communication with the airbag control unit (restraint system module) has been lost. The cause must be checked before it is established whether the control unit is defective.

What airbag equipment does the Leapmotor B03X have?

According to the manufacturer, the Leapmotor B03X has seven airbags. The manufacturer information does not clearly state which airbag types are fitted in detail; the equipment list of your vehicle provides this information.

For the Life and Design equipment lines, the manufacturer gives the same number of airbags. Front, side or head airbags are not broken down further in the manufacturer information.

Assistance systems such as blind-spot assist and lane centring assist complement protection before an accident. In a crash, the airbag control unit controls the triggering of the airbags.

If the airbag warning light is on, have the system checked promptly at a specialist workshop. There, have the fault memory read, the battery disconnected and the control unit removed.

You then create a repair order online and send in the control unit. Processing usually takes 3–4 working days and comprises checking, repairing and testing. After a collision, we erase the crash data during the repair.

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