Abstract
A verification procedure is performed when a tracking device is newly installed in a vehicle. The procedure involves transmitting a command to the tracking device to either disable or enable the vehicle starter. The installer is then prompted to engage the starter to start the vehicle. The tracking device then monitors the voltages on the vehicle's ignition wire and starter disable and starter enable wires going to a starter relay. The tracking device also monitors the state of a starter relay control wire. Measurement of the proper voltages on these wires provides verification that the tracking device has been connected properly. Continuing to monitor these voltages after installation provides an indication when a driver engages the starter in an attempt to start the vehicle.
