What is a Toyota Aygo AB10 airbag control unit?
The Toyota Aygo AB10 airbag control unit is the central safety unit in the vehicle, crucial for occupant protection. It continuously monitors sensors, processes data, and deploys the airbags and seatbelt pretensioners in the event of an accident to ensure maximum safety, while storing important crash data for diagnosis and repair.
This safety-relevant electronic component is responsible for the reliable function of the entire airbag system in the Toyota Aygo AB10, mainly the first generation from model year 2005 onwards.
It integrates all safety-relevant functions and communicates via the OBD interface for diagnostic and error queries.
Why is the Toyota Aygo AB10 airbag control unit defective?
The Toyota Aygo AB10 airbag control unit often fails after an accident because it irreversibly stores accident-relevant crash data and then permanently activates a fault indicator in the cockpit. However, a failure can also be caused by internal electronic errors or communication problems, causing the entire airbag system to fail.
After an accident, the control unit stores the crash data in its internal memory. This blocks the system and requires repair or replacement.
Other causes of failure can be overvoltages or age-related material fatigue, which lead to internal circuit errors.
A defective control unit prevents the airbags and belt tensioners from functioning properly, which significantly impairs the safety of the occupants.
Common error codes for Toyota Aygo AB10 airbag control unit repair
When diagnosing a faulty Toyota Aygo AB10 airbag control unit, the primary error code that points directly to the control unit itself is code B1000. This indicates an internal fault or communication error within the control unit, which activates the airbag warning light and renders the system inoperable.
- **B1000** → Control unit general error/communication → Airbag ECU defective or malfunctioning
Other error codes that affect sensors, belt tensioners or other peripheral components are explicitly excluded from the diagnosis of the control unit itself.
Fixing error code B1000 usually requires a special repair or replacement of the control unit to restore full functionality.
What part numbers are available for the Toyota Aygo AB10 airbag control unit repair?
