What is a Toyota Yaris XP210 airbag control unit?
The Toyota Yaris XP210 airbag control unit is the central safety unit in the vehicle, responsible for monitoring and activating all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of a collision. It receives signals from crash sensors, stores important accident data, and ensures the functionality of the entire SRS system.
It is an essential component of the Supplemental Restraint System (SRS), which detects accidents and maximizes occupant safety. The control unit is also responsible for fault diagnosis and storing relevant system information.
The proper functioning of the airbag control unit is crucial for the passive safety of the Toyota Yaris XP210. A defective control unit can activate the airbag warning light and prevent the system from deploying in an emergency.
Why is the Toyota Yaris XP210 airbag control unit defective?
A Toyota Yaris XP210 airbag control unit often fails due to irreversible crash data stored after an accident, triggering a malfunction, or due to internal electronic component failures. Such defects then lead to the permanent activation of the airbag warning light and require professional repair or replacement to restore safety.
After an impact, the crash data stored in the control unit often cannot be erased using conventional diagnostic tools. This prevents the system from being restarted and results in an error message.
Even without an accident, the control unit can suffer internal damage due to aging, overvoltage, or manufacturing defects. Such electronic failures also manifest as system errors and require comprehensive diagnosis and repair .
Early diagnosis of an illuminated airbag warning light is crucial to determine the cause of the failure and ensure the safety of your vehicle.

- B1000 → Control unit communication error → Internal error in the airbag control unit
- B0108 → Internal error or memory problem → Defective internal memory of the control unit
- B1100 → Memory error in the control unit → Permanent storage of crash data or hardware defect
- B0118 → Electrical fault in the control unit → Short circuit or open circuit in the control unit electronics
- B1141 → Crash data stored, error in the control unit → Triggered crash data blocks the system
These error codes indicate that the workshop must perform a comprehensive diagnosis to identify the exact cause and professionally repair the broken module.
