With this service it is possible to retrieve one or more values of a control unit. This can be information of all kinds and of different lengths such as Partnumber or the software version. Dynamic values such as the current state of the sensor can be queried. Each value is associated to a Data Identifier (DID) between 0 and 65535. Normal CAN signals are meant for information that some ECU uses in its functionality. DID data is sent on request only, and is for information that no ECU uses, but a service tool or a software tester can benefit from.
