Abstract
A vehicle 10 includes an accessory system 40 coupled to an engine control module 26. The accessory system 40 may, for example, be a snow plow. The accessory system 40 is coupled to a first pin 30 and a second pin 32 of the engine control module. When both of the pins are high, the idle speed of an engine 12 is raised so that the speed of the alternator 14 is raised so that a battery 16 may maintain a charging level on the battery.
