1. An apparatus for determining emissions testing readiness of a motor vehicle, comprising:

  • a processor that can be operably coupled to a vehicle diagnostic connector to determine a status of at least one readiness monitor;

    at least one vehicle communication protocol interface operatively coupled to the processor and allows the processor to communicate with the vehicle;

    a multiplexer operably coupled to the processor;

    a computing device interface operably coupled to the multiplexer;

    a housing surrounding the processor, the at least one vehicle communication protocol interface, the multiplexer, and the computing device interface, wherein the housing has a port configured to couple to a computing device;

    an indicator disposed on the housing for indicating the readiness of the vehicle for emission testing; and

    a voltage detection device configured to manage power to the apparatus, and having a power threshold for comparing with the power of a power source, wherein when the power of the power source exceeds the threshold, the voltage detection device allows the apparatus to be powered, and when the power of the power source is below the threshold, the voltage detection device restricts power to the apparatus.
