Measurement and Calibration Using UDS (Unified Diagnostic Services)

The UDS protocol is a vendor-neutral protocol for communication between application tools and control devices.

The CAN bus (CAN) is used as a direct hardware interface to the ECU. It uses UDS to communicate with the ECU.

Some parameters that are displayed in the Hardware Configuration Editor are loaded from the A2L file in advance.

Data capture from several rasters is possible with UDS. Calibration and flash programming are also possible.

Note
Specifications for implementing UDS in ETAS calibration systems can be obtained directly from ETAS.
