Kenworth t800, no bump idle

[joed2323]

I only tried swapping out the cecu under the cupholders. They had diff numbers on them but I think that doesnt matter??

I do know I tried watching the switches on insite ang their is no difference at all for cruise when I activate it or deactivate it, insite shows no change like its not responding.

But when I try the Jake settings, 1,2,3 the status does not change at all on insite like its noy responding but the jakes do in fact work and always did, just not the bump idle.
