I am receiving the following error when I start ECU-TEST / TRACE-CHECK.
ECU-TEST / TRACE-CHECK offers interfaces to work remotely controlled.
The default port for ECU-TEST is 8000 and for TRACE-CHECK 8001.
In this state, ECU-TEST / TRACE-CHECK is still running, but you cannot access the API from outside.
If said port is in use by another program, another port number can be configured by manually creating a registry value:
For this purpose, a DWORD Value xmlrpcPort stating the desired port number needs to be created at
If you want to get rid of the error message, please make sure that no other software is blocking these ports.
Close the respective software and restart your ECU-TEST / TRACE-CHECK.
