Title: Mystery Transmission component
Post by: DonD on May 27, 2012, 09:49 PM
My new to me  '87 Southwind CL A has this on the steering column support. I see what it is but I'd like to know what it does.

The far adjustment hole says: system sensitivity adjustment and the arrows point to "increase". It is plugged into a multipin flat plug, very hard to trace the wires in the very busy under dash area.

I am going to take a guess and it has to do with the cruise control.  What do I win????

That does look a lot like my cruise control module, but it doesn't have a sticker or anything.

It is in fact a cruise control module.  Here is a link to a forum that has additional pictures and discusses it:

The CC does work, a bit balky but it works. Maybe I can "debalk".....better leave alone!

Found this:

Here is the method I used to adjust the cruise control in my 1984 Eagle:

1) Find a lightly traveled road where a 50 mile per hour speed is not unusual and continues for several miles.

2) Place all adjustments to their mid-point.

3) Adjust the low-speed cut in so the cruise control will not engage below 28 mph.

4) Adjust centering so the cruise control controlled speed is 1/2 (0.5) MPH above set speed. This pulls the pedal away from your foot ever so slightly when you engage the cruise control.

5) Adjust sensitivity so the cruise control operates smoothly, and does not allow the speed to vary wildly up or down before compensating.

When adjusted properly, the cruise control works quite well. Speed will vary a bit going up and down hill, but on level roads will hold speed rock-steady. If your unit isn't quite perfect on the level, do the best you can and then use the unit. The unit seems to work better the more it is used.

Note: Steps 3 and 4 seem to affect each other. They may need to be repeated once or twice to get the adjustment just right.
