Hello -
I was staring at my Saturn's cruise control the other day when I noticed that the actual cruise control module under my dashboard has a six-wire connector leading into it. I went to my Haynes Repair manual and looked at the electrical diagram :
Attachment 702
It seems to me that if I can figure out how the
MOVE and
WOT/IDLE signal wires behave, I could suppress the cruise control's desire to open the throttle when going uphill.
The main benefit is that I think I can get the cruise control cutoff for the
BRAKE and the
CLUTCH for free, because I would leave those wires connected.
Detail : Notice that the "brake wire" input to the Cruise Control goes directory to the CC Module and not through the ECU/PCM. That implies to me that Cruise Control Module will ignore the ECU/PCM signal when it gets a signal from the brakes. However, the electrical diagram could be misleading me by leaving information out. That is to say, the ECU/PCM must also be getting the brake signal, so it could also be changing the
MOVE and
WOT/IDLE signals when the brake is applied.
The bad part is that I could (as usual in these things) make the ECU/PCM go crazy and throw a code.
