What is a Mercedes-Benz AMG GT C190 airbag control unit?
The Mercedes-Benz AMG GT C190 airbag control unit is the central safety unit that continuously monitors sensor data and precisely deploys airbags and seatbelt pretensioners in the event of an impact. It stores crash data and signals system errors. This is crucial for vehicle safety and essential for diagnosis in the event of a necessary Mercedes-Benz AMG GT C190 airbag control unit repair.
It is a core component of the Supplemental Restraint System (SRS), specially developed for the Mercedes-AMG GT series C190. The device processes signals from various sensors that detect sudden deceleration or impact events.
It is connected to the vehicle via the CAN bus and controls the deployment of driver, passenger, and side airbags, as well as seat belt pretensioners. Power is supplied via the 12V vehicle electrical system, with capacitors ensuring deployment even in the event of a primary power failure.
The control unit is robustly constructed and mounted in the vehicle's underbody, typically near the driver's footwell or center console. This position protects it in the event of a crash.
It is compatible with all variants of the AMG GT C190, including the AMG GT, AMG GT S, AMG GT C and AMG GT R, as well as the corresponding Roadster models from 2015 to approximately 2023.
Why is the Mercedes-Benz AMG GT C190 airbag control unit defective?
A Mercedes-Benz AMG GT C190 airbag control unit is often considered defective after a crash because it stores accident-relevant data and then locks up. Internal electronic errors, water damage, or overvoltage can also cause failure. A Mercedes-Benz AMG GT C190 airbag control unit repair or replacement is crucial in such cases to restore the vehicle's safety functions.
After an impact, the control unit stores the crash data and is locked for safety reasons. This prevents accidental activation and requires a reset or replacement.
Internal component defects, such as age-related wear and tear on capacitors or faulty solder joints, can also lead to malfunctions. Software errors or corruption of internal data can also render the device unusable.
A power failure or surge in the vehicle's electrical system can damage the sensitive electronics. Water ingress into the vehicle interior, especially near the installation location, can lead to corrosion and short circuits, which can damage the device.
The airbag warning light in the cockpit signals a system defect. A professional diagnosis is essential to determine the exact cause of the failure and initiate a targeted Mercedes-Benz AMG GT C190 airbag control unit repair.
Common error codes for Mercedes-Benz AMG GT C190 airbag control unit repair
Specific error codes tailored to the Mercedes-Benz AMG GT C190 airbag control unit are not publicly available and have not been verified. However, typical problems often manifest themselves as general B-codes, which indicate communication errors or internal defects in the control unit. For a precise diagnosis, the vehicle identification number (VIN) and professional Mercedes-Benz diagnostic software are essential.
The exact error message is crucial for a successful Mercedes-Benz AMG GT C190 airbag control unit repair. The following generic error codes can occur in Mercedes-Benz airbag systems:
- B1000 → Control unit communication error → This code indicates problems with the data transmission between the airbag control unit and other systems on the CAN bus.
- B1050 → Sensor interface error → This may be due to defective or faulty signals from connected acceleration or pressure sensors that the control unit cannot process correctly.
- B1100 → Airbag control unit internal error → This code indicates an internal hardware or software problem in the airbag control unit itself, which often requires replacement or specialized repair.
- B1200 → Airbag ECU power supply faulty → This signals an insufficient or unstable power supply to the airbag control unit, which impairs or prevents its function.
It's important to note that these codes are general examples and have not been specifically validated for the AMG GT C190. A reliable diagnosis always requires the use of vehicle-specific diagnostic tools such as Mercedes-Benz XENTRY.
What part numbers are available for the Mercedes-Benz AMG GT C190 airbag control unit repair?
For the Mercedes-Benz AMG GT C190 airbag control unit, there are no 100% verified, unique OEM part numbers from publicly available sources that are specific to the control unit itself. Frequently cited numbers refer to airbag modules or sensors. Precise identification requires access to official Mercedes-Benz parts catalogs using the vehicle identification number (VIN).
It's important to distinguish between the airbag control unit and the actual airbag modules (such as the driver or knee airbag). The control unit is the control unit, while the modules are the components that are deployed in an accident.
Example part numbers that often appear in connection with the Mercedes-Benz AMG GT C190 are usually for airbag modules, not for the control unit:
- 000-860-19-04-9116 → Mercedes-Benz → Driver airbag (ignition module/inflator)
- A1728600602 → Mercedes-Benz → knee airbag
These numbers are for identification purposes only. To find the correct part number for a Mercedes-Benz AMG GT C190 airbag control unit repair or replacement, we strongly recommend checking the chassis number (VIN) in an authorized Mercedes-Benz parts catalog or at a specialist workshop.
