Durability demonstration vehicle (DDV) testing

Q: Why is pre-DDV testing recommended?

Ascential T&M recommends performing a pre-DDV test to ensure all systems are working as intended prior to the official DDV test. This helps identify and resolve any issues before the certification procedure.

Q: What does DDV testing demonstrate?

DDV testing demonstrates that certain vehicle monitors are able to detect a failure before tailpipe emissions exceed a predefined threshold, as required by the CARB certification procedure.

Visión general

Como parte del procedimiento de certificación CARB, los fabricantes están obligados a demostrar que ciertos monitores son capaces de detectar un fallo antes de que las emisiones del tubo de escape superen un umbral predefinido. WinterPark Engineering recomienda a nuestros clientes realizar una prueba DDV previa para garantizar que todos los sistemas funcionan según lo previsto antes de la prueba DDV "oficial". Podemos llevar a cabo tanto la prueba DDV pre y oficial, así como solucionar cualquier problema encontrado durante la prueba pre-DDV.
