What is an Infiniti QX50 P15 airbag control unit?
The Infiniti QX50 P15 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 module, often referred to as the SRS control unit, is critical for the safety of vehicle occupants. It processes signals from various crash sensors in the vehicle.
Based on this information, the airbag control unit decides on the precise deployment of the airbags and seatbelt pretensioners. It is typically located centrally in the vehicle, often under the center tunnel or in the dashboard area.
Why is the Infiniti QX50 P15 airbag control unit defective?
The Infiniti QX50 P15 airbag control module can malfunction if it stores crash data after an impact and then becomes blocked. A malfunction can also occur if the module is incorrectly programmed or incorrectly coded to the vehicle's VIN. Internal communication errors or voltage problems can also lead to failure.
After an airbag deployment, the control unit stores indelible crash data. This data prevents the module from continuing to function normally, necessitating a reset or replacement of the Infiniti QX50 P15 airbag control unit repair.
Another common reason for failure is missing or incorrect programming of the module after installation. The airbag control unit must be coded to the vehicle identification number (VIN).
Communication errors in the vehicle bus (CAN bus) or power supply issues can also cause the airbag control unit to appear defective. Such problems require a detailed diagnosis to resolve the failure.
Common error codes for Infiniti QX50 P15 airbag control unit repair
When diagnosing a faulty Infiniti QX50 P15 airbag control module, specific error codes are often read, indicating collision data, communication issues, or missing programming. These codes are critical for correctly repairing or resetting the module to restore full functionality of the airbag system.
The following error codes are typical for problems that are directly related to the airbag control unit itself and may require an Infiniti QX50 P15 airbag control unit repair:
- B1000 → Control unit communication error → Problems with the internal communication of the module.
- B1425 → Rear collision detected → The module contains crash data that cannot be deleted after an accident.
- B1427-55 → Airbag control unit replaced, not programmed → The module is not coded to the vehicle.
- B142A → Ignition voltage problem → Insufficient or fluctuating power supply to the control module.
- B142X → Collision detected, crash data available → General collision detection with stored crash data.
- U1010 → CAN communication error with airbag control unit → Problems with data transmission in the vehicle CAN bus.
These codes are important indicators of the nature of the defect and initiate the necessary steps for repairing the Infiniti QX50 P15 airbag control unit. A professional diagnosis is essential.
What part numbers are available for the Infiniti QX50 P15 airbag control unit repair?
For the repair or replacement of the Infiniti QX50 P15 airbag control unit, the OEM part number 98820-5UB0A is primarily relevant. A common alternative is part number 631265000B from supplier Autoliv, which is exactly compatible with this vehicle series. Other numbers usually refer to airbag cushions or sensors.
Part number 98820-5UB0A is the original part number used by Infiniti for the SRS Airbag Control Module in the QX50 P15. This number is listed and verified in official spare parts databases.
The Autoliv part number 631265000B is an alternative OEM number, as Autoliv is a major supplier for Infiniti airbag systems. Both numbers identify the correct airbag control unit for the P15 series.
It is crucial that after an Infiniti QX50 P15 airbag control unit repair, the module is programmed to the vehicle identification number (VIN). Without this coding, the system will not function correctly and will display error codes.
Other Infiniti part numbers, such as 98515-3JB6A or 98510-5NA8A, belong to airbag cushions or other sensors, not the central control unit. Carefully verifying the part number is essential for a successful repair.
