What is a Toyota Yaris XP150 airbag control unit?
The Toyota Yaris XP150 airbag control unit is the central safety unit in the vehicle that controls and monitors the Supplemental Restraint System (SRS). It processes sensor signals during a collision to precisely deploy airbags and seatbelt pretensioners and stores important crash data for diagnostics.
This electronic module is crucial for occupant safety, as it activates life-saving restraint systems in an emergency. It collects data from various sensors, such as impact and acceleration sensors, throughout the vehicle.
After an accident, specific crash data is permanently stored in the control unit. This data must be professionally erased before the vehicle can be safely used on the road again to ensure proper functioning.
Why is the Toyota Yaris XP150 airbag control unit defective?
The Toyota Yaris XP150 airbag control unit often becomes defective because it stores crash data after an accident that needs to be erased, or due to internal electronic malfunctions such as power supply problems, memory corruption, or communication errors that make repair unavoidable.
Common causes of failure are internal defects in the module itself, which can manifest themselves as specific error codes such as B1100 (memory error) or B0108 (power supply problems).
Another trigger for a necessary repair of the Toyota Yaris XP150 airbag control unit is the error code B1141, which indicates that crash data is stored in the system after an accident and requires a reset.
A permanently illuminated airbag warning light usually indicates a defect. Such a problem will result in the vehicle failing its MOT and compromise safety.
