2001 W-900B Intermittent Cruise

Hello! I have a 2001 W-900B and the cruise control has been having this intermittent issue. It mostly happens after I have used it to adjust up the idle, then when I am on the road and try to set the cruise it won't take and if I hold the switch in the set position the check engine light will come on and flash 5 times. It doesn't do this all the time just on occasion. I installed a Bully Dog Big Rog tuner and it doesn't show that any DTC's are present. Anyone have any ideas or experienced this before?

Thank in advance.

 

I will take a look. Thank you.

 

I am back on this issue now. When you try to set the cruise it flashes a 6/2 code which Motor Power Kenworth says is a low coolant code and has nothing to do with it, but that is only time it does it. I finally had my wife ride along and count the flashes to I could get the code right. I am not sure what the button looks like that the pedal might be resting on. I didn't see anything out of the ordinary under the throttle pedal.

 

thank you I will take a look at that too....

 

...so i tapped on the clutch switch with a screwdriver (mostly because I could really get to it to remove it) and flipped the throttle pedal back and forth and smacked it down good a few times (engine off of course) and so far the cruise has been working. Not sure what I did to get it back.....
