4.8What is a Polestar 5 1st generation airbag control unit?
In the Polestar 5 1st generation, the airbag control unit is the central control unit of the restraint system (SRS). It evaluates the data from the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners fire. After an accident it stores crash data and locks itself.
The control unit is installed in the Polestar 5 1st generation (since 2026) and stays active throughout operation. When the ignition is switched on, it checks itself as well as the connected sensors and airbag modules. If it finds a deviation, it switches on the airbag warning light and stores the finding in the fault memory.
Because all sensors and firing units come together at this unit, a defect affects the whole restraint system and not just a single airbag. That is why the warning light is usually the first sign that a check is due.
Why is the Polestar 5 1st generation airbag control unit defective?
Most often the cause is crash data stored in the Polestar 5 1st generation airbag control unit after an accident, even if no airbag deployed. An ordinary diagnostic tool cannot delete it. Ageing electronic components, cold solder joints, moisture and corrosion on connectors, and voltage spikes are other possible triggers.
An accident leaves its mark in the unit even when hardly anything is visible from the outside. The fault entry returns after being cleared because the control unit retains the crash data.
Other causes build up gradually. Over the years, components on the circuit board age, solder joints become brittle, and moisture that gets in makes contacts in the connectors corrode. Voltage spikes, for example from a weak battery or after a jump start, can put additional strain on the electronics.
An airbag symbol that stays lit in the instrument cluster, a fault memory that cannot be cleared, or a diagnostic tool with no connection to the control unit point to a defect. If your Polestar 5 1st generation shows one of these symptoms, you should have the unit checked.
Common error codes for Polestar 5 1st generation airbag control unit repair
The known error codes for the Polestar 5 1st generation concern, on the one hand, the loss of communication with the restraint system and, on the other, an interruption in the firing chain of the restraint system. The code in question shows where the system noticed the fault.
Below are the codes that occur in connection with the airbag control unit of this vehicle. The list is not complete.
- U0151 → Communication with the restraint system lost
- B15381B → Interruption in the firing chain of the restraint system
Error codes are read from the fault memory with a diagnostic tool. A single entry does not allow a reliable conclusion as to whether the control unit is actually defective, since connectors, wiring or an airbag module may equally be the cause. Only a check of the unit provides clarity.
What part numbers are available for the Polestar 5 1st generation airbag control unit repair?
On the label of the control unit you will find the part number, which defines its exact version, because the numbers within a model series differ depending on equipment and year of manufacture. We do not yet know of any numbers for the Polestar 5 1st generation, so please copy the number into the repair order yourself after removal.
Note the number from the label as soon as the unit has been removed, and enter it when you create the repair order. This establishes which version it is. However, whether the unit is defective is only clarified by reading out the fault memory or by the check.
The route to repair consists of a few steps. First have the fault memory read out, then disconnect the battery and remove the control unit. Next you create a repair order online and send in the unit. Airbag24 usually needs 3–4 working days for checking, repairing and testing; your own unit is returned to you.
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.
