I am needing some help programming the high idle for the PTO. 2008 international 7000 series. I have all the Navistar software. All the parameters shock that the idle is programmed to 1400 rpm. The question i have is the drive shaft speed sensor does not show value, like its thinking. Does this value need to be a zero to engage the high idle. Thank you all in advance for any help you can provide me!
