I have been trying to get my 2016 df250 into iac fixed mode but it does not seem to work. I never get the buzzer and the SDS is showing the iac is not fixed at 30%. Not sure what I am missing on the procedure. I start the engine, let it warm up, shift into gear then Back to neutral. I turn the key to start 5 times in 10 seconds but nothing happens. Any idea what I am I missing? I also see the manual says to fully close throttle, is there something I need to do for the throttle to be fully closed? What should the TPS be showing for this procedure to work?
any ideas would be very much appreciated.
