Hyundai Genesis BH Airbag Control Unit Repair

What is a Hyundai Genesis BH airbag control unit?

The Hyundai Genesis BH 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, also called the SRS Control Module, is designed for the precise deployment of the front, side, and curtain airbags, as well as the seat belt pretensioners. It processes signals from various crash sensors in real time.

The control unit also contains a non-volatile memory (EEPROM) that records critical crash data and error codes after an accident. This data can then be read out and the module professionally reset.

Why is the Hyundai Genesis BH airbag control unit defective?

A Hyundai Genesis BH airbag control unit can fail due to accident damage, internal electronic malfunctions, or age-related wear and tear. After an impact, it stores irreversible crash data, requiring a Hyundai Genesis BH airbag control unit repair or replacement to restore the safety systems.

The control unit often reports an error after a crash because crash data is permanently stored in memory, and the airbag warning light remains activated. Even without an accident, a Hyundai Genesis BH airbag control unit can fail, for example, due to an overvoltage or an internal component defect.

Errors in communication with sensors or other vehicle systems can also signal a failure. Early diagnosis is crucial to restoring the vehicle's safety functions.

Common error codes for Hyundai Genesis BH airbag control unit repair

When repairing the Hyundai Genesis BH airbag control unit, specific error codes are crucial for identifying defects directly within the control unit. These codes indicate communication problems with sensors or internal errors within the module that require professional diagnosis and indicate airbag system failure.

• B1000 → Control unit communication error → The airbag control unit has detected a fault in its internal communication or cannot communicate with other systems.
• B1329 → Front Impact Sensor - Communication Error → The control unit reports that communication with a front impact sensor is faulty.
• B1334 → Front Impact Sensor Active - Communication Error → The control module detects a communication error with a front impact sensor that is reported as "active".
• B1670 → Airbag control unit stores crash sensor errors → The control unit has stored crash data after an accident and reports this as an error condition.
• B1742 → Side impact sensor communication error, driver side → The airbag control module does not have correct communication with the side impact sensor on the driver side.
• B1748 → Side impact sensor communication error, passenger side → The control unit reports a fault in the data exchange with the side impact sensor on the passenger side.

These error codes are direct indicators of problems that require a Hyundai Genesis BH airbag control unit repair. A specialist workshop can read these error codes and determine the exact cause of the failure.

What part numbers are available for the Hyundai Genesis BH airbag control unit repair?

For Hyundai Genesis BH airbag control unit repair, the exact Hyundai OEM part number 95910-B1800 is the primary reference point. A related replacement or supplier number is XC2361A-72F, which is often associated with this original part and is crucial for compatibility.

Part number 95910-B1800 is verified as a genuine part for the airbag control unit of the Hyundai Genesis BH (model years 2008-2016). It applies exclusively to the control unit itself, not to sensors or other airbag components.

The number XC2361A-72F is listed as a compatible or alternative part number for the same module. When repairing the Hyundai Genesis BH airbag control unit, it is crucial to match these numbers to ensure the correct replacement part.

Other specific manufacturer numbers from suppliers like Bosch or Continental are limited in common databases for this specific Hyundai Genesis BH airbag control unit. Therefore, always pay attention to the OEM number for successful replacement part procurement or professional repair.
