Electronic control units contain datamemorieswhichcantemporarily or permanentlystore
technical information aboutthevehicle's operat‐ingstate, component loads, maintenancerequirements andtechnicalevents or malfunc‐tions.
Ingeneral,this information documentsthestateof a component part, a module, a system orthesurroundings such as:
Roperatingstatus of system components (e.g.fill levels, batterystatus, tire pressure)
Rstatus messages concerningthevehicle orits individual components (e.g. number ofwheelrevolutions/speed, longitudinal accel‐eration, lateral acceleration, display offas‐tened seat belts)
Rmalfunctions orfaults in important systemcomponents (e.g. lights, brakes)
Rinformation onevents leadingtovehicledamage
Rsystemreactions in special driving situations(e.g. airbag deployment, intervention ofsta‐bility control systems)
Rambient conditions (e.g.temperature,rainsensor)
