What is an Infiniti JX35 L50 airbag control unit?
The Infiniti JX35 L50 airbag control unit is the central safety unit that instantly activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors, stores relevant crash data, and ensures the proper functioning of all components of the vehicle's Supplemental Restraint System (SRS).
This module plays a critical role in safety by processing data from acceleration sensors and seat belt pretensioner sensors.
It is integrated directly into the vehicle's on-board systems via the CAN bus to ensure seamless communication and precise control.
Why is the Infiniti JX35 L50 airbag control unit defective?
An Infiniti JX35 L50 airbag control unit can fail because it stores crash data after an accident and then becomes locked, or due to internal hardware or software errors such as an EEPROM problem. Incorrect vehicle voltage or communication errors can also lead to failure, requiring professional Infiniti JX35 L50 airbag control unit repair.
After an impact, the control unit stores indelible crash data that blocks further functioning.
Internal component defects or a problem with the memory (EEPROM) can seriously disrupt the normal operation of the module and lead to failure.
Fluctuations in the vehicle electrical system voltage, whether too high or too low, can also cause damage to the control unit.
Communication problems via the vehicle's CAN bus are another common cause of airbag control unit malfunctions.
In many cases, the module is not actually "broken" after an accident, but simply needs to be reset and reconfigured to restore full functionality.
Common error codes for Infiniti JX35 L50 airbag control unit repair
When diagnosing a faulty Infiniti JX35 L50 airbag control unit, specific error codes will appear that indicate internal problems or communication errors. These codes are crucial for identifying the exact cause of the failure and performing a targeted Infiniti JX35 L50 airbag control unit repair, ensuring vehicle safety.
- B1220 → Internal Control Module Error → A specific control module error for Infiniti JX35 L50 modules.
- B1239 → Internal Control Module Error → Another Infiniti-specific control module error.
- B1000 → Control unit communication error → Problems with data transmission between the control unit and other vehicle systems.
- B0091 → SRS control unit configuration error → The module is incorrectly configured or the configuration is corrupted.
- B0092 → SRS control unit EEPROM error → An internal memory error in the control unit, often after a crash.
- B0094 → SRS control unit crash data memory full → The memory for accident data is full and prevents further function.
- B0095 → SRS control unit crash data history error → Inconsistencies or errors in the crash data history.
- B0096 → SRS control unit acceleration sensor error → The integrated acceleration sensor in the module is faulty.
- B0097 → SRS Control Unit Fuse Sensor Error → A fault in the control unit's internal fuse sensor.
- B0098 → SRS control unit incorrect installation position → The module was installed in an incorrect position.
- B0099 → SRS control unit vehicle communication bus error → A malfunction in the communication bus from the vehicle to the control unit.
- B1100 → SRS warning lamp circuit malfunction → A malfunction in the airbag warning lamp circuit in the instrument cluster.
- B1101 → SRS control unit battery voltage too high/too low → Problems with the supply voltage of the control unit.
- B1102 → SRS communication line open/shorted → A short circuit or an open circuit in the communication line.
- B1425 → Rear collision detected (module reset required) → The system has registered a rear collision, which requires a module reset.
- B1427-55 → Module must be configured after control unit replacement → The airbag module must be reconfigured after replacement.
A professional diagnosis is essential to accurately read these error codes and resolve the cause of the airbag control unit failure.
What part numbers are available for the Infiniti JX35 L50 airbag control unit repair?
The exact OEM part numbers for the Infiniti JX35 L50 airbag control unit are difficult to find in independent sources, as they can vary depending on the vehicle and model. For a reliable Infiniti JX35 L50 airbag control unit repair, it is advisable to request the part number directly from an official Infiniti dealer, providing the vehicle identification number (VIN), or to use professional databases such as TecDoc.
Generic sources or online stores often do not list specific OEM part numbers for the Infiniti JX35 L50 control unit or only offer components such as sensors.
100% verification of compatibility can only be done through official Infiniti parts catalogs or directly from the control unit manufacturers (e.g. Bosch, Continental).
During an "Infiniti JX35 L50 airbag control unit repair," the existing control unit is often reset and a new one is not necessarily required, making the search for an exact part number less critical as long as the original module is functional.
It is important to note that different models of the JX35 L50 or QX60 L50 may have different hardware and software versions of the control unit, even if they are from the same series.
