WHY DD DIAGNOSE SOFTWARE SHOW engine #1 is not currently transmitting the data contant cruice control status,
OFF ROAD CRUISE IS WORKING. AND I APPLY PARKING BRAKE ITS COME ON IDLE,
Sounds like your park brake switch is bad. The park brake switch lets the engine ecm know if you are using cruise switches for cruise or fast idle. This is a very common switch to fail. The air manifold is located in lower section of the middle dash. I am attaching a diagram of the air manifold with all the switches. Check the park brake cutout switch. Unplug it and stick a paper clip between the 2 wires and try fast idle. Unplug paper clip vice versa.
Also, if your truck is equipped with optimized idle, the park brake circuit goes thru a couple more switches and could be one of them. Does your speedo and tach work? I have to run out for a while with family but I will reply back at my next login. Let me know the results.
I have probe , parking brake cut off switch show ground and 6.7v and when I will apply parking , 6.7v show ground (mean green light in probe)
