You need the Volvo software and a control module or laptop computer which is compatible with the motor's electronic engine controls. Note that modifying the settings on a commercial/heavy goods vehicle carries many potential consequences. Some countries mandate the speed such vehicles must be set at, and altering those settings might be a criminal act.
You go to a shop which has the software appropriate to the engine your truck has and have them adjust it. If it's not your truck to do this with, the ECM will be password protected, and you won't be able to.
You find a shop with the appropriate software for the engine ECM in your truck, and have them adjust it. If it isn't your truck to do this with, the ECM will be password protected, and you won't be able to.
If it's your truck do this with, and you're in a country where it's legal to do so, then you go to a service center with the software which corresponds to your engine (in N. America, Volvo trucks are currently available with Cummins or Volvo engines... Caterpillar and Detroit Diesel were also available in the past), and have them adjust the settings. If it's not your truck to do it with, you don't.
You need the Volvo software to do this. It's programmed into the engine ECM.
That's programmed into the ECM. You'd need to hook a computer with the appropriate software for the engine to the ECM, and adjust the settings there. If it's not your truck to do this with, then the ECM will most likely be password protected, and you won't be able to do this.
One can purchase Volvo truck parts at: Auto trader, Parts Seek, Market Book, Truck Paper, Trucker to Trucker, HGV Direct, Heavy Truck Parts, Top Speed.
Change speed? It has to be done at a shop. They plug computer to truck and change speed with the computer.
You can't. The idle speed is controlled by the Engine Control Module or ECM.
You take it to a Volvo Dealer and they plug in a laptop and reprogram some parameters on the ECU in the truck.
The speed controls are programmed into the engine ECM. If it's not your truck to do this with, the ECM is probably password protected.
Depends on what you're trying to find out. You can find out some information direct from Volvo.
