and procedure for control unit programming
using the PIWIS Tester'.
Repeat control unit programming by entering

extended logging must be started using the key
combination •Ctrl“ + •L“.
Extended logging records diagnostic software
data, particularly vehicle communication data,
which is required for analysing the issues that
caused programming to be aborted.
