Abstract
A diagnostic system for a hybrid vehicle comprises a processor module and a motor control module. The processor module outputs a seed value. The motor control module controls torque output by an electric motor of the hybrid vehicle, receives the seed value, generates a final key value based on the seed value, and outputs the final key value to the processor module.
