IIDTool Common Tasks

Monitoring Battery Voltage
Starting with IIDTool v2.18, you don't need to do ANYTHING to monitor battery voltage. Plug your IIDTool in the diagnostics port and wait. There is no need to enter any menus. After the tool boots up you will see "IIDTool Ready" on the LCD, which will soon change into the battery voltage live value.
