"Activate" Command Menu






NOTE: When a system tunction is activated with the Scan Tool, the Motronic control module is made to do something that it would not otherwise do in the course of its normal operation. This may cause diagnostic trouble codes to be generated in other systems which are dependent on the Motronic system.


Activation should only be carried out with the ignition switch in the ON position.

The Intellegant Saab Tester (ISAT) scan tool display texts below are presented in the same order as the commands shown under ACTIVATE in the ISAT scan tool menu structure.
