Read Data by Identifier
The purpose of this service ($1A) is to provide the ability to read the content of pre-defined ECU data
referenced by a Data Identifier (DID) which contains static information such as ECU identification data
or other information which does not require "real-time" updates (e.g.: the VIN Vehicle Identification
Number).
Note: "Real-time" data is intended to be retrieved via the Read Data By Packet Identifier ($AA)
service.
This service has to be send out with exactly one DID, that's information is requested. Depending on the
required information the service has to be configured. The Setup button in the Main Diagnostic Setup
window could activate the dialog box shown below.
The corporate defined DIDs could be selected from the provided list or the hexadecimal value of a user
defined DID might be entered. Acknowledge the setup by OK.
