Summary

As part of the CARB certification procedure, manufacturers are required to demonstrate that certain monitors are able to detect a failure prior to tailpipe emissions exceeding a predefined threshold. WinterPark Engineering recommends our clients perform a pre-DDV test to ensure all systems are working as intended prior to the “official” DDV test. We can perform both the pre and official DDV test as well as troubleshoot any issues found during the pre-DDV test.
