TI Number No. 236-22 Important information on handling the integration test on the PIWIS Tester as part of a workshop campaign 1 WNT1 Workshop campaign - Reprogramming Connect control unit and the central computer (PCM) (Cluster 37) The integration test on the PIWIS Tester checks the conformity of the control unit system of vehicles on the basis of the approved customer service installation specification (Service Installation Instructions). This will detect an unapproved or no longer up-to-date control unit system. When new control unit software is provided, the Service Installation Instructions are also amended. This will take effect immediately with the related PIWIS Tester release. As a result, all relevant vehicles are tested against the currently approved software system after the PIWIS Tester release has been installed. Depending on the result of the check, all relevant control units must be updated when prompted to do so by the PIWIS Tester. Following this workshop campaign, all control units to be programmed as per the integration test in the PIWIS Tester will be displayed as "red" when the relevant PIWIS Tester release is published and must therefore be updated.
