Abstract:
An exhaust after-treatment system for a vehicle including a dosing agent that is selectively injected into an exhaust from a dosing agent supply includes a first module that determines a level of a dosing agent source. A second module selectively impedes vehicle operation by adjusting an engine operating mode if the level of said dosing agent source is below a threshold level.
