    On my 04 379(c15) the engine fan light only lites when the fan override switch is turned on. If the temp gets to about 205 the fan will come on but the light stays off, I would like to see the light on with both. Is it possible to program the ecm to do this. thanks CME-309

    Another one of our turcks had the same issue, and yes, you have to have it programmed to turn the dummy light on when in auto mode.
