    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

    Yeah, sounds like whoever reprogramed it never restored your configuration back into the ECM. If they have any clue what they're doing programing they should have it saved, so maybe get with them and see if they saved it and can load the configuration settings back in.
    If not send me a PM and I can help you set it up so it all works again.
