From the first phone call, the order processing, to the shipping everything was done very quickly and professionally. Now I still have to send the repaired unit to the Swedish workshop and then hopefully the Honda can finally pass the HU there again (failed because of the red light for the airbag). Today the message came from SWE, the car is running again, the red light is off and the HU was also passed. Once again many thanks for the help in need. Keep it up and maybe word will also spread in SWE that Airbag 24 does great work. Regards Gerd

This essential module, also known as the Restraint Control Module (RCM), is responsible for the continuous diagnosis of the entire airbag and restraint system (SRS).
It processes data from various sensors in the vehicle to precisely and quickly trigger airbags and seatbelt pretensioners in the event of an impact.

The Subaru Legacy BN airbag control unit may be defective because it stores crash data after an accident and then becomes disabled for safety reasons, requiring repair or replacement to restore airbag function.

- 11 → Airbag control unit faulty / airbag main line open → The cause is a defect in the airbag control unit itself or an interruption in the main power supply to the airbags.
- B1872 → Airbag control unit error (cushion airbag) → The cause is a problem in the airbag control unit that affects the function of the cushion airbag.
- B1877 → Error in the airbag control unit (seat airbag) → The cause is a problem in the airbag control unit that affects the function of the seat airbag.
