technicalinformation aboutthe vehicle's operat‐
ing state, component loads, maintenance require‐
ments and technicaleventsormalfunctions.
In general,this information documents thestate
of acomponent part, amodule, asystemorthe

In addition to providing theactual controlunit
function,this dataassists themanufacturer in
detecting and rectifying malfunctions and opti‐
mizing vehicle functions. The majority of this data
is temporaryand is onlyprocessed in thevehicle
itself. Onlyasmall portion of thedataisstoredin
theevent or malfunction memory.
When your vehicle is serviced, technicaldata
from thevehicle can be read out by service net‐
work employees (e.g. workshops, manufacturers)
or thirdparties (e.g. breakdown services). Serv‐
ices include repair services, maintenancepro‐
cesses, warrantyclaimsand quality assurance
measures, forexample. The read out is per‐
formed via thelegally prescribed portfor the
diagnostics connection in thevehicle. The
respectiveservice networklocations or thirdpar‐
ties collect, processand use this data. They
document technicalstatuses of thevehicle,
assistinfinding malfunctions andimproving qual‐
ity and aretransmitted to themanufacturer,if
necessary. Furthermore, themanufacturer is sub‐
ject to product liability.For this, themanufacturer
requires technicaldatafromvehicles.
Malfunction memories in thevehicle can be reset
by aserviceoutletaspartofrepair or mainte‐
nancework.
