    2001 KW t2000 n14 celect plus redtop.

    New to me truck and I'm still working out the kinks. The cruise and Jake do not work. When I turn the switches on they do light up. When I am running the truck I noticed the parking light (pb red circle) is still lit on the dash display.

    Im wondering if this is related to the Jake cruise issue. Anyone know where that switch is? Pulled the stereo and looked at the valves but didn't see an obvious culprit.

    Broken clutch return spring. There's a micro switch near the top of the pedal that is normally closed. If the pedal sags even like 1/4", it opens that switch.
    Hold pedal up with your foot and see if the cruise works.

    on our older trucks, IH's in fact, the plastic bushing on the brake pedal pivot broke, causing the brake pedal to sag. check that as well.

    I would say that park brake warning light is unrelated to your issue. Cruise control (for high idle) and jake should work with the park brake on. Likely a clutch switch issue.

    As for the PB light, more than likely you either have a short to power on that warning light circuit. Or the pressure switch for that light is stuck closed.

    Had the same issue with a KW t600 but without the parking brake light. I was able to bypass the clutch switch but wasn't it. bypass brake light switch wasn't it either. After hours of labor at the KW shop. They found a corroded wire in the main harness that powers the brake light switch. Main harness in front of the firewall close to the top of the eng. Was weird because my brakes where working. Anyway i wasn't able to find any wiring diagram resources online thats why i gave up and left up to the "experts" :)
