1. A method for validating a vehicle component, the method comprising:

  • detecting an electronic connection between a vehicle electronic control unit (ECU) and a vehicle power unit over a communications bus;

    comparing a vehicle power unit start-up program passcode stored in a memory of the vehicle ECU to at least one predetermined ECU passcode;

    authenticating the vehicle power unit to start-up with the vehicle ECU when the vehicle power unit start-up program passcode matches the ECU passcode;

    transmitting a power up signal from the vehicle ECU to the vehicle power unit when the vehicle power unit is authenticated;

    monitoring the communications bus for when the vehicle power unit is disconnected from the communications bus;

    erasing the vehicle power unit start-up program passcode from the memory of the vehicle ECU when the vehicle power unit is disconnected from the bus;

    erasing the predetermined ECU passcode corresponding to the vehicle power unit start-up program passcode when the vehicle power unit is disconnected from the communications bus;

    storing a new vehicle power unit start-up program passcode in the memory; and

    re-authenticating the vehicle power unit with the vehicle ECU when the new vehicle power unit start-up program passcode matches another of the predetermined ECU passcodes.
