What is a Daewoo Sens T150 airbag control unit?
The Daewoo Sens T150 airbag control unit is the central safety unit used in Daewoo vehicles to control the occupant restraint systems. It continuously monitors sensors, stores relevant crash data after an impact, and ensures the reliable deployment of all airbag modules. This component is critical to vehicle safety.
It's a specialized electronic control unit (ECU). The control unit ensures the precise, millisecond-fast activation of the airbags and seatbelt pretensioners in the event of an accident.
Why is the Daewoo Sens T150 airbag control unit defective?
The Daewoo Sens T150 airbag control unit often malfunctions because it stores crash data after an impact, blocking the system and necessitating repair. Internal electronic errors such as defective memory chips, processor problems, or power supply failures can also lead to failure. This is often indicated by an illuminated airbag warning light.
Internal memory errors such as EEPROM problems (error code B1001) are a common cause of a defect. They prevent proper booting or saving of important operating parameters.
An internal processor error (error code B1004) can cause the control unit to stop responding. Communication errors with other vehicle systems are also typical signs of a device defect.
Common error codes for Daewoo Sens T150 airbag control unit repair
When repairing the Daewoo Sens T150 airbag control unit, only control unit-specific B error codes are relevant, indicating internal problems with the unit. These error codes enable precise diagnosis by identifying communication errors, memory problems, or power supply failures directly at the control unit. They are crucial for targeted repairs.
- B1000 → Control unit communication error → Communication between the airbag ECU and other systems is disrupted.
- B1001 → Internal memory or EEPROM error → There is a defect in the internal memory or the programming blocks of the control unit.
- B1002 → Control module self-test failed → The airbag control module failed its own diagnostic test.
- B1003 → Power supply error in the control unit → The power supply to the airbag ECU is faulty or interrupted.
- B1004 → Internal processor error → There is a malfunction in the main processor in the control unit.
- B1005 → ROM checksum error → The internal software or firmware of the control unit has an error.
- B1010 → Watchdog error (control unit not responding) → The control unit is no longer responsive or does not respond to system requests.
- B1011 → UDS communication error with other control units → Malfunction in the standardized diagnostic communication with connected ECUs.
- B1020 → Airbag control unit diagnostic error (generic) → A general internal diagnostic error has occurred in the airbag control unit.

For which Daewoo Sens T150 models is this airbag control unit compatible?
The Daewoo Sens T150 airbag control unit is primarily designed for the Daewoo Sens model from approximately 1998–2002, where it was installed as standard. It may also be partially compatible with the Daewoo Nubira from 1997–2003, depending on the trim level. A thorough check using the vehicle identification number (VIN) is essential before any repair.
The airbag control unit was primarily developed for the Daewoo Sens and was installed as a standard component in models from approximately 1998 to 2002. It controls all essential airbag functions in these vehicles.
Compatibility with the Daewoo Nubira, especially models from 1997 to 2003, may vary depending on the specific trim level and the installed airbag generation. It is advisable to check this carefully before attempting a repair or replacement.
The correct functioning of the airbag system is safety-critical. Therefore, a thorough model and year check, as well as a comparison with the vehicle identification number (VIN), is strongly recommended before installation.
Process and safety during the Daewoo Sens T150 airbag control unit repair
The Daewoo Sens T150 airbag control unit repair includes detailed fault diagnosis, the replacement of defective electronic components, and a complete system reset after an accident or malfunction. This specialized repair is essential to restore the full functionality and safety of the airbag system, as it is a safety-critical component that requires the utmost precision.
After the airbag system is deployed, the control unit stores crash data that blocks it. This data must be professionally erased and the unit reset to make it operational again and to extinguish the airbag warning light.
The repair involves checking and, if necessary, replacing internal circuits and microprocessors. A professional repair ensures that the airbag system is fully functional and safe again.
The airbag control unit meets high safety standards and is protected against electromagnetic interference and vibrations. The firmware is specifically tailored to the respective vehicle model and may only be modified by trained personnel.
Due to its safety-critical function, the Daewoo Sens T150 airbag control unit repair should only be performed by qualified technicians. Manufacturer-specific diagnostic equipment and tools compatible with OEM part numbers should be used.
