Write Data by Identifier<br />
The purpose of this service ($3B) is to provide the ability to change (write/program) the content of predefined<br />
ECU data referenced by a Data Identifier (DID), which contains static information like ECU<br />
identification data, or other information, which does not require "real-time" updates.<br />
This service has to be send out with exactly one DID and the data that shall replace the previously<br />
stored information for this DID. Therefore the Setup button in the Main Diagnostic Setup window could<br />
activate the dialog box shown below.<br />
DID<br />
Only one Data Identifier, which is supported by the ECU, shall be included in the request message.<br />
Corporate defined DIDs could be selected from the provided list or the hexadecimal value of a user<br />
defined DID might be entered.<br />
Data<br />
Input the data that shall be assigned to the DID as hexadecimal values in byte format, divided by<br />
commas as shown above. The number of data bytes is dependant upon the size of the data referenced by<br />
the Data Identifier parameter.<br />
Acknowledge the setup by OK.<br />
Note: This service should be requested using physical addressing. See the Main Diagnostic Setup<br />
window for details about addressing.<br />
