In regardds to the high idle mode it can serve two purposes. The factory one where the truck will sense that the temperature of the coolant is less than 32*F When high idle is selected the truck will go into high idle after the oil has been circulated for X time. Once this happens the truck will then go into high idle mode. Where the truck automatically holds the engine RPMS around 1200. This is normal and both safe fore the motor. The truck will continue to stay in this mode until the coolant reaches normal operating temperatures. The seconded option to this is if you have a PTO option on your Allison transmission. Which most Allison's have the ability to have PTO. This is used for things like water pumps, or hydrolic pumps for tow trucks. Which then you would have a separate switch to operate this and cold is not a factor.
