Does anyone know the parameters for the "full" exhaust brake to work on the 2017 CTD? It is different from the 2011 I owned and it doesn't seem to be working. It worked the day I bought it, but the last 2 days going to work I tried to use it and nothing. My speed was 30-40 mph, down hill, no accelerator. Thanks in advance.
