C0072Brake Temperature Too High
- Generic OBD-II code · Chassis
- How the car detects it
- Set when the brake or stability module estimates that brake temperature has risen above a safe threshold. Few vehicles measure rotor temperature directly; most run a thermal model that integrates braking force, speed and time to estimate how hot the brakes are, and warn or adapt control when overheating is likely, for example on a long descent. The code is stored when the modelled or measured temperature exceeds the limit, prompting a driver warning and sometimes reduced regenerative blending or electronic brake-force changes. It is advisory and protective rather than a wiring fault; braking and ABS continue. Persistent setting can indicate a dragging brake or an implausible model input. The entry follows the SAE J2012 generic definition and electronic brake-system thermal modelling.
