Can we do this? (aka The DIY Cruise Control Thread)

First it is my belief that the 07 meters are not even programmed for cruise because there is not even a connector for the LED and no trace for it either. you do not have a tach am i correct Nick? therefore the icon should be under the speedo needle to the right of it and from the pics i see none. So Scott i don't think that checking the shift registers will do anything if the controller doesn't have the program that will allow it to send the signal to the icon.

Second some of you may remember this i was trying to figure out a way to switch from metric to mph and vice versa, well thanks to your pics Nick i came to the conclusion that this also is not possible to "hack", I read the Repair manual Meter section and the only way to switch this is through the Intelligent tester.

here is the list of things that can be Customized through the intelligent tester:

Display (Item) Default Contents Setting
KEY REMIND SOUND SLOW Changes key reminder buzzer
intervals FAST / NORMAL / SLOW
LIGHT REMIND ON Turns light reminder buzzer ON
and OFF ON / OFF
SEAT BELT WARN D/P ON Turns seat belt warning buzzer
ON and OFF D/P ON / D ON / P ON / D/P OFF

UNITS BY REGION Different for every region Changes drive monitor display
units
KM/L JP / KM/L / ML/G US / ML/
G UK / KM/G

I realize that the LED is not there and that there is a good chance that the microcontroller is not programmed to support the cruise LED, but two days ago I would have said the same for the ECM, when he found that the wire didn't exist in pin 40, and the cruise clutch switch wiring didn't exist.

I say check the shift register output for the heck of it, as I don't believe that all 16 outputs are in use.

Just as a side note, I think it would be worthwhile if a mod re-named this thread to something like "DIY Cruise Control how-to, 2007-2009".

The current thread title won't be helpful in future searches :D

Is there a DIY for mounting/wiring the clutch switch? I haven't gotten it yet so I'm not even sure what it looks like/where to put it.

Take a look at this DIY on installing cruise on a Matrix. It shows the Clutch Switch installation:

Looks like the plug for this switch should already be hanging somewhere under the dash, if I'm reading this correctly. Seems pretty straight forward.

Correct. Plug is hanging there. Remove bolt, screw in switch, plug in connector.

Alright you guys, I'm home and I used my Cruise Control to and from work...it was GREAT! Definatly worth the trouble. But of course right now it's kind of a pain to always be wondering "Did I turn it on yet? Is it on or off right now? I sure wished this LED worked." :)

I just got done reading all these replies. I will definatly take the meter apart again and check all those pins "just for the heck of it," cause it will be nice if that works out. But if not we'll have to figure something else out.

PK198105, no I don't have the tach in the combination meter, but I did install one aftermarket...I think that doesn't effect this process. And I do also see many empty solder points on the PCB...LED's, IC's and some other stuff.

Also, I didn't see the clutch switch wire hanging down under the dash, but I will search again just to make sure.

Anyway, I probably won't have any time to do this until saturday, so hang in there guys and I will keep checking in here everyday to see what's shakin'. I will post more pics on saturday with my results from the voltage tests. Thanks guys!

Sounds good. I have a circuit design in my back pocket for making the LED work, without changing to a dual pole switch, in case we need it...

Nice.

Any ideas on where I can find a steering column cover that already has the opening for the cruise stalk? My car's basically brand new and I don't wanna mess up the OEM cover if I can help it.

Anybody know the part #?

[mikenacarato]

i thought the cruise came through the steering wheel, not the column cover?

[CTScott]

Cover, Steering Wheel Boss, Lower: 45184-52130-B0

This is for one that has factory cruise control, (and it is the plastic back of the wheel, not the column cover).

[MGargano]

Ohh so it's actually the back of the steering wheel, not the column cover? Doh! This fits & color matches the US 09?

Yes.

[MGargano]

Thanks, just ordered from TRDSparks. Should be getting the fogs, OEM combo stalk, shrouds, clutch switch, and boss this weekend to go with the cruise stalk. I figure I'll pull the steering wheel once and be done with it.

CTScott, I checked every pin (just to be sure) on those two IC's (IC500,IC501) and the pins for the blank spot where the third IC should go (IC502). Nothing :( they were all the same after I hit the Cruise switch. I grounded my meter to the frame and checked the pins with the red lead of the meter while it was on DC Voltage "20V" setting. That's how I do it right (I don't think I'm that dumb, but just to make sure) I guess it's not gunna happen the easy way as usual :)
