Once the system has displayed all the modules, it will go into the "Manual" mode. This allows you to select each module individually using different combinations of DIC buttons. Manual mode can also be entered during the Automatic sequence by pressing any button except "E/M." (Pressing E/M will cause you to exit the diagnostic mode.) When the display shows "Manual Diagnostics," select a module by pressing the "Options" button to scroll forward, or the "Trip" button to scroll back. Once a module is selected, the DTC(s) from that module will be displayed. If more than one code is present, press "Gauges" to scroll forward or "Fuel" to go scroll back. To exit the diagnostic mode at any time, press "E/M."
