Values relating to the different commands are stored in the control module's internal memory. These values are updated continuously, some of them as soon as the ignition switch is turned to the ON position although most of them require the engine to be started. When the engine is switched off the control module stores the most recent value recorded.

This value is displayed next time the ignition switch is turned to the ON position but it is not relevant for commands requiring the engine to be started. The Intellegant Saab Tester (ISAT) scan tool will then display an incorrect value.

The Intellegant Saab Tester (ISAT) scan tool displays below are presented in the same order as the commands listed under READ FUNCTIONS in the ISAT scan tool menu structure.
