technical stuff about the cruise control lever, for all those 3 spoke steering wheel swappers. Options

[njccmd2002]

Well i just swapped my steering. I have the dilemma of the cruise control. I have read its a possibility of just joining some wires and give it a try, however bad cruise control can mean acceleration or inability to turn it off. so i decided to see about it.

My new matrix steering did not come with one, buying one is not a problem. However the 7th gen is a 2 wire module and the 6th gen has 3 wires.

as far as comands options on 6gc, i took it apart, very simple switch, consists of 3 resistors wired in a way to provide multiple resistance values for each option. Thats how it does it. By resistance, and the computer reads this.




The question is how to effectively use the 7th gen making sure you get all the functions.

I set my multimeter at 2k setting and here are readings...

1. Cruise On / Off (this is actually a zero resistance switch. ) this is the white and white/black together

The following are the red and white/black together

2. Cancel ( the resistance value on this is 0.419 )
3. Set/Coast ( the resistance value on this is 0.198 )
4. Res/Acc ( the resistance value on this is 0.068 )

here is the basic set up



However the 7th gen has 2 wires, and i need to get ahold of one to take it apart and study it and modifiy it..



Yes the Cruise on the wheel is better.

Until i get my hands on a 7th gen, it is unk what functions can be done or replicated safely. As both computer modules can be different. Ill keep posting...

got my hands on a triple spoke cruise and different values and just two wires.

The following are the red and white together

2. Cancel ( the resistance value on this is 1.542 )
3. Set/Coast ( the resistance value on this is 0.631)
4. Res/Acc ( the resistance value on this is 0.240 )


so this is different information, this was off a rav 4. now i dont think these same resistances will trigger the cruise computer. And if the resistances are the same in a 7th gen celica cruise.

pretty much both have resistors in series,

2. Cancel 3 resistors
3. Set/Coast 2 resistors
4. Res/Acc 1 resistor

my goal will be to swap resistors, tough job due to size, i have to make holes larger.


here are the pics of different layout.




another view



removed resistors, and had my old cruise resistors.



shaved the pockets



and soldered the resistors needed.



no i will make the wire splicing.
