When I bought my 2008 VNM, I had no idea of the 5 min shutdown or that it was a parameter that couldn't be disabled in the diag computer yourself. You would figure when you bought a vehicle, put the key in and it starts and that's it. I'm old school and bought a newer (to me) 2008 VNM, it shutdown on me when I was inspecting the engine and couldn't find the problem. I started it again and sat there looking at the dash, then it did it again but this time I seen the warning on the screen. Went through the computer with a fine tooth, couldn't find a shutoff for the shutdown so I called service dept and they told me I'd have to pay to get them to turn off what shouldn't be there in the 1st place. I then tried the OBD2 route, but they want $3-800 for the dongles to communicate with another $2k worth of software. I remember having full control of my truck but now I got pay service to disable idle shutdown. I'm not O&O, I'm a private old guy hauling a 5th wheel trailer. Does anyone have any other hidden things that should be modified for a retired guy not to have any more surprizes? I have to pay the full hour! OR has anyone figured out a less expensive way to navigate that system?
THANX fo listening.
