Additional instructions if programming is aborted
Information
If individual programming steps or rework could not be carried out correctly, see Workshop Manual for
the basic procedure for control unit programming using the PIWIS Tester Workshop Manual '9X00IN
Basic instructions and procedure for control unit programming using the PIWIS Tester - section on “Fault
finding”'
In the event of a fault, logging must always be created during programming using •Ctrl“ and •L“ using
the PIWIS Tester.
As a general rule, if programming is aborted during programming, programming must be continued.
The entire sequence can be started again at any time using the campaign code. The control unit that has
already been programmed is skipped, or programming is started via the integration test. Starting to use
the integration test is faster.
