Yaw-rate sensor
Measures how quickly the car rotates around its vertical axis.
In a defined body location or integrated sensor unit.
Its measurement is compared with steering and wheel information for stability functions.
A balance observer checking whether the car is turning as expected.
DSC warnings can involve calibration, signals or supply rather than a mechanical brake fault.
Inspect and service using model-specific guidance, especially after a collision; warning lights require diagnosis.
Calibration, matched modules and post-collision work may dominate cost. An illuminated warning does not identify a replaceable part.
BMW DSC compares actual motion with driver intent; wheel speed alone cannot describe the car’s rotation.
