Normally this means the probe is not in thevehicle’s exhaust pipe or there is a hole in the exhaust pipe.The level of dilution checked for by the software can be altered in the Minimum Dilutionfield of General Setup (Main menu > Maintenance > Setup > General Setup).Idle TestDilution value is measured by calculating CO + CO 2 . If CO + CO 2 is less than thesetting in the Minimum Dilution field, then FGA signals the error.The Idle Test follows almost the same sequence as the TSI Test but it tests theengine at idle speed. Whereas the TSI Test requires the engine to be run at twospeed ranges, the Idle Test allows the engine to idle naturally.To run the Idle Test on the pocket PC,1. Tap the Automatic Tests button on the main screen.— The Automatic Tests menu opens.2. Choose Idle.— The Idle Test begins.✓ For more information about the TSI Test Sequence see TSI Test,page 2D-1.2D-6
