Swapping and Redesignation Policy

The following information is provided only as a guide to the status of a "Swapping and Re-designation Policy Agreement" for each verified company. Please read the Formal Agreement for specific details. Not all diesel emission control strategy (DECS) manufacturers allow component swapping and/or re-designation.  A DECS manufacturer that allows these practices may have grounds to deny a warranty claim if component swapping or DECS re-designation is performed and either the policies approved by the DECS manufacturer are not followed, or the DECS manufacturer’s policies are not approved in writing by the Air Resources Board (ARB).

1. SWAPPING is defined as the movement of designated parts between different vehicles/applications within the same common ownership fleet which utilize same DECS.

2. RE-DESIGNATION is defined as the movement of a used verified DECS from an appropriate engine/application and installation to another engine/application meeting the terms and conditions of the DECS Executive Order within the same common ownership fleet.
