Engine/Transmission (1998.5 - 2002) Cruise Control Tip

[Archive]

I know this post is not entertaining like the B. O. M. B. threads but... ...
I just got my service manual and looked up speed control to see if it covered the problem I've been having with my cruise control while pulling my trailer. What it says is:
"The Speed Control has an adaptive strategy that compensates for vehicle-to-vehicle variations in speed control cable lengths. When the speed control is set with the operators foot off the excelerator pedal, the speed control thinks there is excessive cable slack and adapts. If the lift foot sets are continually used the overshoot/undershoot condition will develop. " To "unlearn" this condition you need to turn the cruise off wait ten seconds, turn it back on. This must be done 10 to 15 times while going at a steady speed (no acceleration or dedeceleration) to completely "unlearn" the overshoot/undershoot condition.

How bout that? I think I got mine real screwed up. As my frustration grows I set it a jillion different ways trying to control the damn thing as I am ramming down a hill with the hammer down and listening to my wife ***** about the magic cruise control.
I thought I would pass this along with the advise to spend the bucks and get one of these service manuals.

Boy, I must be more brain dead tonight then usual Ron. I read sectin 8H (Speed Control System) of my Service Manual and found nothing about the adaptive cable process. Am I looking in the right section?

rwv,
Brain dead?... .....
I don't think so. My manual is '99. I see you have a '00... ... . Maybe it doesn't apply or who knows? The bit is titled "Overshoot/Undershoot Following Speed Control Set" 8H-4
I would imagine nothing has changed but?
Good Luck,
Ron

It's there in the 99 book. I found it while trying to figure out how to modify the cruise control vacuum solinoid for a fast idle application... .

The dealer REPLACED the speed control in my friends truck, only for the problem to come back again, before we figured out what was REALLY wrong. Way to play idiot replace! Eventually there was a TSB issued to address the problem.

willyslover,
My BOMBing days are coming soon... ... . Got to sell my old van before I can join you guys ! I am lucky that DD is only 20 miles from my house. Seems like lots of stuff is happening and I guess I will hold out for a short while until I make up my mind which way to go. Just past 36k and Dodge warranty. In the mean time I will try to learn more about the truck and pass on anything I think interesting.
You guys keep the info coming... ... .
Can't help it but everytime I see your handle I think "Monica"..... haha
