What is a SsangYong Rexton Sports airbag control unit?
The SsangYong Rexton Sports airbag control unit is your vehicle's central safety unit, activating all occupant restraint systems in the event of an accident. It continuously monitors sensors, stores relevant crash data, and ensures the proper functioning of all airbag modules for maximum protection.
This electronic module is the brain of the passive safety system and is crucial for the deployment of airbags and seatbelt pretensioners. It processes signals from acceleration and impact sensors in real time to react precisely in an emergency.
The control unit is typically installed centrally in the vehicle to ensure optimal protection and reliable communication with all components of the airbag system.
Why is the SsangYong Rexton Sports airbag control unit defective?
A SsangYong Rexton Sports airbag control unit often fails due to internal components such as memory or software errors, crash data being stored, or voltage fluctuations damaging the electronics. This leads to malfunctions of the entire airbag system and requires a professional SsangYong Rexton Sports airbag control unit repair.
Internal memory errors (EEPROM errors) are a common cause of airbag control unit failure, as they corrupt important calibration or crash data. Internal hardware errors can also damage the control unit, impairing communication or deployment.
Faulty software or firmware within the module can also lead to failure, often manifesting as unexplained system messages or non-erasable error codes. Low battery voltage in the vehicle can trigger temporary communication errors, which the control unit may interpret as a defect.
Common error codes for SsangYong Rexton Sports airbag control unit repair
SsangYong Rexton Sports airbag control unit repairs often involve reading specific OBD-II B codes that indicate internal problems with the control unit itself. These codes indicate errors in the airbag control unit's communication, memory, or software, not external sensors or seatbelt pretensioners.
- B1000 → Control unit communication error → Interruption of data transmission within the airbag ECU.
- B1100 → Internal memory error → Damage or corruption of data in the internal memory of the control unit.
- B1200 → Voltage fluctuations in the control unit → Insufficient or unstable voltage supply to the module.
- B1300 → EEPROM error in the control unit → Error in the non-volatile memory, often due to incorrect data or defects.
- B1400 → Airbag control unit self-test error → The control unit fails its internal system test.
- B1500 → Software/firmware error in the control unit → Problems with the internal software or programming.
- B1600 → Internal hardware error in the control unit → Defect in physical components of the control unit board.
- B1700 → Communication error with airbag sensors (only detected on the control unit side) → The control unit cannot communicate with connected sensors.
These B-codes are typical of control unit-specific problems and require a precise diagnosis using a specialized OBD airbag scanner. It's important to note that these codes do not indicate problems with crash sensors, seat belt pretensioners, or seat occupancy mats.
What part numbers are available for the SsangYong Rexton Sports airbag control unit repair?
Specific part numbers for the SsangYong Rexton Sports airbag control unit are difficult to find due to model variations, but reference numbers from similar Rexton models can be helpful in SsangYong Rexton Sports airbag control unit repairs. A thorough check using manufacturer catalogs is essential for correct identification.
Although no specific part numbers are available directly for the Rexton Sports model, the following numbers can serve as a general reference for SsangYong Rexton airbag control units:
- 86250-08140 (SsangYong Original)
- 86250-08141 (SsangYong Original)
- 86250-09061 (SsangYong, e.g. for KYRON)
- 86250-21031 (SsangYong, e.g. for RODIUS)
These numbers usually refer to control units that were also installed in other Rexton variants or related SsangYong models such as the Rexton II (GAB_). Always consult official SsangYong parts catalogs or professional spare parts databases to determine the exact part number for your Rexton Sports model and ensure a successful SsangYong Rexton Sports airbag control unit repair.
Technical specifications for your SsangYong Rexton Sports airbag control unit
The SsangYong Rexton Sports airbag control unit, often manufactured by Siemens, is a robust 12-volt module with multiple interfaces and self-test functions, essential for precise airbag deployment in the event of an accident. Its technical features are designed for maximum reliability and diagnostic capability, essential for any SsangYong Rexton Sports airbag control unit repair.
The control unit controls airbag deployment by evaluating acceleration and impact signals. It is powered directly by the vehicle's electrical system with a fused 12-volt power supply to ensure full functionality even in the event of an accident.
It features multi-pin connectors that ensure a secure connection to sensors, the airbags themselves, and the vehicle network. Integrated protection mechanisms such as short-circuit monitoring and fault detection ensure system integrity.
Compatibility and installation position for the SsangYong Rexton Sports airbag control unit repair
The airbag control unit is primarily designed for the SsangYong Rexton Sports, although it is also compatible with certain variants of the Rexton and Actyon Sports I with similar engine configurations. It is typically securely located in the center console or under the dashboard and connected via yellow-coded connectors, which must be taken into account during a SsangYong Rexton Sports airbag control unit repair.
Compatibility extends primarily to models from the early 2000s to the 2010s, depending on the exact part number and equipment. It is often found in variants with a 2.7L diesel engine and is partially identical to models such as the SsangYong Actyon Sports I (QJ).
The installation position, protected from moisture and mechanical influences, is crucial for longevity. The connectors are color-coded (usually yellow) and often have gold-plated contacts to minimize corrosion and signal loss.
Important information about SsangYong Rexton Sports airbag control unit repair
Repairing the SsangYong Rexton Sports airbag control unit is often a cost-effective alternative to replacement, as specialized workshops can repair the module, for example, by erasing crash data or replacing defective components. Variants exist depending on the vehicle's equipment, so a thorough analysis is important.
Repairs can include resetting crash data, fixing internal memory errors, or replacing specific defective components. This is often cheaper than purchasing a new part and avoids unnecessary electronic waste.
Newer Rexton generations from 2017/2020 onwards feature advanced control units that offer additional safety features and deeper integration with assistance systems; the module described here primarily refers to older models. The control unit always operates according to strict ISO safety standards to ensure maximum reliability and rapid airbag deployment.
