Customer reply replied 2 years ago
you did not tell me what to look for in the conversion rate.
Technician: roybelding, Shop Foreman Freightliner trucks replied 2 years ago

Sorry, I was traveling this morning.

It needs to have at least 75% conversion rate for it to complete. The inlet and Outlet DPF temps need to be within 50 degrees of each other as well.
