1. A method for regenerating an after-treatment system of a vehicle, the method comprising:
monitoring a first operational parameter of a first component of the after-treatment system;
monitoring a second operational parameter, different to the first operational parameter, of a second component of the after-treatment system;
determining if the first operational parameter of the first component is outside a first threshold range;
determining if the second operational parameter is approaching a second threshold range;
in response to the first operational parameter being outside the first threshold range and the second operational parameter being within the second threshold range, initiating a regeneration sequence of the after-treatment system configured to regenerate at least the first component of the after-treatment system;
determining if the first operational parameter of the first component is outside of a third threshold range, larger than the first threshold range; and
in response to the first operational parameter not being outside of the third threshold range, initiating a regeneration sequence configured to regenerate the first component and a second component.
