What is a Toyota Yaris XP130 airbag control unit?
The Toyota Yaris XP130 airbag control unit is the central electronic unit of the passive safety system (SRS), responsible for the reliable control and monitoring of all occupant restraint systems in the event of an accident. It receives signals from sensors, stores relevant crash data, and thus ensures the proper functioning of the vehicle's airbags and seatbelt pretensioners.
This essential component continuously monitors the status of the entire airbag system. It detects faults early and signals them via the airbag warning light in the cockpit.
In the event of a repair, a defective control unit can often be reset or repaired to restore full functionality.
Why is the Toyota Yaris XP130 airbag control unit defective?
The Toyota Yaris XP130 airbag control unit often fails because crash data is irretrievably stored after an accident or internal electronic errors such as short circuits occur. This can also be caused by overvoltage, aging components, or water damage, making it necessary to repair or replace the module to restore full safety.
A failure typically results in the airbag warning light remaining permanently illuminated. This signals that the safety system is no longer fully functional.
Diagnostics via OBD interface can read precise error codes that provide information about the exact cause of the defect.

When does a Toyota Yaris XP130 airbag control unit repair make sense?
A Toyota Yaris XP130 airbag control unit repair is advisable if the unit has stored crash data after an accident or has internal errors such as communication problems without physical damage. This is often a more cost-effective and environmentally friendly alternative to purchasing a new unit, especially if only a crash data reset or the correction of a software error is required.
The repair usually includes erasing the crash data and a comprehensive test of the internal electronics.
A repaired control unit is then ready for use again "plug and play" and in most cases does not require additional programming.
Specialist workshops offer specialized services for the repair of these safety-relevant components to ensure the optimal functioning of your system.
