What is a SsangYong Korando e-Motion C300EV airbag control unit?
The SsangYong Korando e-Motion C300EV airbag control unit is the central safety unit that precisely controls occupant restraint systems such as airbags and seatbelt pretensioners in the event of an accident or system failure. It continuously monitors sensors, stores relevant crash data, and ensures the correct functioning of all components for maximum safety.
This critical electronic unit monitors and controls the deployment of airbags and other restraint systems in the vehicle. Repairing this control unit offers a cost-effective alternative to replacement, especially in cases of malfunctions caused by electronic defects or faulty sensor communication.
It operates on the DC 12V vehicle electrical system and uses a microcontroller-based real-time unit with a safety-relevant embedded software stack. Communication with other vehicle systems takes place via CAN bus and LIN bus interfaces.
The device processes inputs from front, side, and curtain airbag sensors, as well as seatbelt pretensioner and crash sensors. Its output signals control the airbag inflators, seatbelt pretensioners, and warning lights in the instrument cluster.
Why is the SsangYong Korando e-Motion C300EV airbag control unit defective?
The SsangYong Korando e-Motion C300EV airbag control unit frequently fails due to internal electronic damage caused by aging, overvoltage, or moisture, or because it stores irretrievable crash data after an accident. These so-called hard codes require a specialized repair service because they cannot be erased using standard diagnostic tools, which activates the airbag warning light.
Internal electronic errors, such as those indicated by error code B1015, can occur even without an accident. Such malfunctions directly trigger the airbag warning light, indicating a problem with the SRS system.
After a vehicle collision, the airbag control unit registers specific crash data that prevents the system from functioning properly until a professional reset is performed. This requires a repair to clear these hard codes and restore the unit's operational readiness.
Other causes of **failure** include communication errors (e.g. B1000) or general SRS system errors (e.g. B1139) that affect the device's ability to monitor or correctly activate safety elements.
Common error codes for SsangYong Korando e-Motion C300EV airbag control unit repair
When **repairing** the SsangYong Korando e-Motion C300EV airbag control unit, specific trouble codes are diagnosed that indicate internal problems with the unit, rather than with sensors or seatbelt pretensioners. These codes signal a **failure** of the control unit's function and are crucial for accurate **diagnosis** and repair by a qualified workshop.
- B1000 → Control unit communication error → The airbag control unit cannot communicate correctly with other vehicle systems.
- B1015 → Airbag control module error → An internal defect or malfunction has occurred in the control module hardware or software module.
- B107E → Airbag module related error → A general error within the airbag module that affects functionality.
- B1139 → Error within the SRS system → The control unit detects a system error that impairs the overall capability of the restraint system.
- B207F → SRS control unit error → A critical error in the SRS control unit that prevents the entire airbag system from operating.
