I need help on a cat motor c15 Acert I have tried everything we just put this motor in and before the fan would not run all the time now the fan is running constantly and will not shut off I think something needs to be turned on or off in my configuration and parameters on cat et we had to get the ecm re programmed and I think something needs to be set or reset and my Jake’s and cruise control also aren’t working and I think the same thing needs to be done there
C15 acert new install, fan running constantly.
