Abstract
An apparatus for communicating with an electronic control module on an engine of a machine from a remote location is disclosed. The apparatus includes an electronic controller associated with a power supply on the electronic control module. A sensor is connected to the electronic controller for sensing an engine parameter indicative of the operating state of the engine. A communications interface for transmitting and receiving a communication signal is associated with the electronic controller. An ignition switch is connected to the power supply, such that when the ignition switch is in the off position, the electronic controller is powered down. The electronic controller is subsequently powered up if a communication signal is received from the remote location. This in turn allows a sensed engine parameter to be communicated to the remote location, and further allows machine information to be downloaded from the remote location to the electronic control module while the ignition switch remains in the off position.
