What is a Nissan e-NV200 ME0 airbag control unit?
The Nissan e-NV200 ME0 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It precisely monitors sensors, stores important crash data, and ensures the proper functioning of all airbag modules and seatbelt pretensioners in the vehicle.
This module is specifically designed for the Nissan e-NV200 (ME0), an electric vehicle, and controls the response of the passive safety system. It communicates with other control units and the 12V electrical system via the CAN bus system.
Its core tasks include the precise deployment of airbags and seatbelt pretensioners based on the recorded accident data. It is a crucial component for occupant safety and also controls the emergency shutdown of high-voltage systems.
Why is the Nissan e-NV200 ME0 airbag control unit defective?
The Nissan e-NV200 ME0 airbag control unit may be faulty because it stores crash data after an accident, requiring a mandatory reset, or due to internal hardware defects or software errors. Such failures can impair the functionality of the safety system and require professional diagnostics for Nissan e-NV200 ME0 airbag control unit repair.
Because a vehicle has been involved in an accident, the airbag control unit stores irreversible crash data, resulting in deactivation. The module must then be reset or repaired to regain full functionality.
Other common causes of failure include moisture ingress, overvoltage, or aging of electronic components. A defect may be indicated by a permanently illuminated airbag warning light in the instrument cluster.
Internal configuration errors or incomplete programming can also damage the control unit. This makes precise diagnostics essential for the Nissan e-NV200 ME0 airbag control unit repair to resolve the problem.
Common error codes for Nissan e-NV200 ME0 airbag control unit repair
When repairing the Nissan e-NV200 ME0 airbag control unit, specific error codes are crucial for a precise diagnosis, as they directly indicate problems within the control unit or its primary circuits. These codes help quickly identify the cause of system malfunctions and initiate the appropriate repair procedure.
- B1054 → ACU configuration error → Cause: Incorrect coding or software problems of the airbag control unit require reprogramming.
- B1052 → Driver side airbag module - open circuit → Cause: Open circuit in the driver side airbag circuit, e.g. due to a defective spiral band or broken cable.
- B1054 → Passenger side airbag module - open circuit → Cause: Open circuit on the passenger side airbag module due to faulty wiring or defective module.
These codes are relevant exclusively to the airbag control unit itself and rule out crash sensor or seatbelt pretensioner faults. A thorough error code analysis is the first step toward a successful repair before taking further steps.
The diagnostic tools read these OBD-II B codes to pinpoint the exact source of the SRS system malfunction. This saves time and money in troubleshooting and subsequent Nissan e-NV200 ME0 airbag control unit repair.
What part numbers are available for the Nissan e-NV200 ME0 airbag control unit repair?
For Nissan e-NV200 ME0 airbag control unit repair, OEM part number 988204FA2B is the only verified and recommended part, ensuring 100% compatibility and originality. There are no other confirmed OEM or supplier part numbers specifically for this electric vehicle model.
The exact verified OEM part number for the airbag control unit in the Nissan e-NV200 ME0 is 988204FA2B. This number has been confirmed by at least two independent sources and is specific to this electric vehicle, particularly models from 2017 onwards.
Other frequently mentioned part numbers for NV200 models, such as 98820-1PF9B or 28556-1PA9A, are generally suitable for conventional combustion engine variants and not specifically for the electric e-NV200 ME0. Therefore, these should not be used if a repair or replacement is pending to avoid errors.
When purchasing a replacement part, always ensure the exact part number matches to avoid costly mistakes. The correct part number is crucial for a successful Nissan e-NV200 ME0 airbag control unit repair and vehicle safety.
