What is a Nissan Cima F50 airbag control unit?
The Nissan Cima F50 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle. This system is critical to the safety of the vehicle's occupants.
It acts as the brain of the passive safety system, processing signals from acceleration and impact sensors. Based on this data, it makes lightning-fast decisions about whether to deploy airbags and seatbelt pretensioners.
Why is the Nissan Cima F50 airbag control unit defective?
A Nissan Cima F50 airbag control unit can fail due to internal components failing due to aging or electrical surges. An accident or improper repair attempts often lead to failure, requiring a comprehensive diagnosis and, if necessary, professional repair. This damage significantly compromises vehicle safety.
Common causes include internal short circuits, software errors, or a stored crash record that wasn't deleted after an accident. If the airbag control unit is defective, the SRS warning light usually stays on.
A failure can also be caused by external factors such as moisture or vibration. This malfunction requires a specialized workshop to diagnose and repair the problem.
Common error codes for Nissan Cima F50 airbag control unit repair
During Nissan Cima F50 airbag control unit repairs, specific error codes often occur that directly indicate problems with the airbag control unit. A precise diagnosis of these codes is crucial to identifying the exact cause of the failure and restoring vehicle safety. These error codes often require a specific approach.
- B1000 → Control unit communication error → Error in the internal communication of the control unit or to the CAN bus.
- B0091 → Airbag control unit problems → General malfunction of the airbag ECU electronics.
- B1427-55 → Airbag ECU must be configured after replacement → Reconfiguration is necessary after replacing the control unit.

What part numbers are available for the Nissan Cima F50 airbag control unit repair?
For Nissan Cima F50 airbag control unit repairs, exact OEM part numbers are crucial, but not always readily available. Nissan typically uses formats like 98820-***** or 28556-***** for these systems, which must be verified for a successful repair or replacement. These numbers are vehicle-specific and depend on the year of manufacture and the equipment.
Since there are no universal part numbers, these must be determined using official Nissan parts catalogs or TecDoc databases. The exact part number is necessary to ensure part compatibility and avoid further errors.
A professional repair shop will determine the exact part number using the vehicle identification number (VIN) or specialized Nissan diagnostic software. This is the only way to ensure the correct airbag control unit is used for your Nissan Cima F50 model.
