Measures after changing the control module: Add
WARNING: This page is about a different car, the 2009 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
When the control module is fitted and in some cases SPS programmed, Tech 2 must be used to "marry" the control module to the car. Access the menu "All" and select control module under "Add/Remove". Then select "Add" and follow the instructions. The ignition key must be in the ON position. TIS 2000 may need to be used.
This happens with regard to data:
Characteristics files are downloaded, security codes are loaded, bus lists are updated, data in other control modules is updated and trouble codes are deleted from all control modules.
