A method of resetting an active emissions system error indictor associated with a vehicle. The method comprises performing a first requesting step and a second requesting step until the active emissions system error indicator resets in response to the first or second requesting steps. In one embodiment, the first requesting step comprises requesting a first type of information (e.g., information from a first vehicle oxygen sensor) from a vehicle computer associated with the vehicle, and the second requesting step comprises requesting a second type of information (e.g., information from a second vehicle oxygen sensor) from the vehicle computer. In a particular embodiment of the invention, an electronic tool, such as a bi-directional scan tool, is used to perform the first and second requesting steps.
A method of resetting an active emissions system error indictor associated with a vehicle, said method comprising performing a first requesting step and a second requesting step until said active emissions system error indicator resets in response to at least one of said first or second requesting steps, and wherein:
A method of resetting one or more active emission system error indicators associated with a vehicle, said method comprising the steps of:
