1. A method of testing an electrical system of an electric vehicle, comprising:
- operating the electric vehicle;
coupling a test device to a databus of the electric vehicle;
monitoring data on the databus and retrieving information related to current flowing into a system of the electric vehicle with the test device during the step of operating;
monitoring data on the databus and retrieving information from a sensor of the vehicle related to a voltage of the electrical system with the test device during the step of operating;
providing instructions to an operator which instruct the operator to operate the electrical vehicle in a specific manner;
recognizing when certain conditions have been met with the test device during the step of operating the vehicle; and
diagnosing the electric vehicle with the test device based upon the monitored current and the monitored voltage.
