Abstract
A device for notifying an operator of the readiness of a vehicle for emissions testing includes a control logic for evaluating the status of each of a plurality of the monitors of an on-board diagnostics (OBDII) system of the vehicle. Once the vehicle is determined to be ready for emissions testing based on the status of each evaluated monitor of the OBDII system, an indicator light is illuminated and/or an audio signal is emitted to notify the operator.

11. A method for determining when a vehicle is ready for emissions testing and notifying an operator of the same, comprising the steps of:
-
continuously evaluating monitors of an on-board diagnostics (OBDII) system of a vehicle through a device connected to the diagnostic link connector of the OBDII system; counting the number of monitors reporting as “
not ready”
; andnotifying the operator when the number of monitors reporting as “
not ready”
is less than or equal to a predetermined threshold, and indicating that the vehicle is ready for emission testing, based on a status of each evaluated monitor. - View Dependent Claims (12, 13, 14, 15)

16. A method for determining when a vehicle with an on-board diagnostics (OBDII) system is ready for electronic interrogation of the OBDII system as part of an emissions inspection, comprising the steps of:
-
connecting a notification device to the OBDII system, said notification device having a control logic capable of evaluating a status of one or more monitors of the OBDII system; evaluating the status of said one or monitors of the OBDII system; and notifying an operator when the control logic of the notification device determines that the vehicle is ready for the electronic interrogation of the OBDII system based upon its evaluation of the monitors of the OBDII system. - View Dependent Claims (17, 18, 19, 20, 21)
