When a vehicle comes into a dealership, the first thing to access in WEBDCS should be the Warranty Vehicle Information Screen. This page provides VIN-specific information which is necessary to determine what emission coverage a vehicle has. Depending on which state the vehicle was certified for and sold in, coverage on emission parts can vary from car to car.
For example: If a VIN is typed into the Warranty Vehicle Information screen and PZEV appears as the Emission Type, that vehicle qualifies for the 15 year/150,000 mile warranty on a corresponding PZEV part. To determine if a part is covered under PZEV, you would refer to the Warranty/HPP Coverage Inquiry, also located in WEBDCS. If the results show that the part is covered under the 15 year/150,000 mile PZEV emissions warranty and the PZEV certified vehicle is registered in a PZEV state, then the 15 year/150,000 mile emissions warranty applies.
