V1 Clutch relearn?

[Lndshrk Steve]

I've got a no crank, no fuel pump problem. I'm getting communication and codes P0230, P0807 and P0808. I can't believe the little clutch switch needs to learn anything, but I've seen dumber things on cars. I've been following ALOT of "no start" "no crank" posts and tried many of the fixes with no luck. I have done a key relearn and fixed a communication problem so I now have 60 ohms between OBDII pins 6 & 14.
My wife keeps saying "This was suppose to be fun . . ." Yes, dear, it WAS suppose to be fun.
I can only beat my head against a wall for about two hours a day, so if you have any suggestions, I may not get back to you right away. But as always, thank you all for any and all help.

You do need to do a clutch relearn if you replaced the switch, but I am not certain it would result in codes if you don't do it.

It's been a while now since I've built my car, and I've forgotten more than I remember at this point, but I'll offer words of encouragement, as someone that had electrical demons for a while: it's frustrating right now, yes, but it is OH SO worth it once the car is on the road and you're enjoying it. I'd build another one if I had to, to keep on enjoying it.

I should be able to post the correct diagnostic steps for those codes for the later model donor this evening when I get home.

Coincidentally I just performed a clutch relearn this weekend trying to overcome my issues. I'd point you to this thread below for some details but one hurdle you no longer have to overcome is the 32x bit version and you don't need VMWare, the COM port is irrelevant. You can run 64x Windows 10 (I used Pro) and run the autoinstaller (see youtube vid).

When/if you do the autoinstall, make sure your Windows Security > Virus & Threat detection is off and when you go to GDS2 you'll need the internet to update your drivers / licenses. Yes, you're probably giving your current laptop spyware so use a hard drive specific for this install. After you connect via Tech2Win, I'd turn your security back on and disconnect from the internet and think of that HDD as the Tech2 only hdd.

I noticed there wasn't a straight up how-to on the VXDIAG Tech2 tool, so I wanted to make a write up so no one else got confused on the installation. I hope this helps. Those of you who have potentiometers for pedal sensors will need to do a clutch-relearn should you replace that sensor...

Thanks for the encouragement. I probably needed that more than anything.

Use a hard drive specifically for this install!!! That doesn't sound good or even doable.

In the abundance of caution in an unideal scenario to save money from actually having to buy a Tech2, it's a small price to pay. If you no longer use the Tech2 hdd you can reformat it and use it for something else - the hdd doesn't have to be big. You could also use a large usb > boot windows from that > do the Tech2 thing. Many ways to skin the cat

If I decide to do this, I'll ask you to put that in english

Buy a cheap separate laptop to do only the Tech2 clone. Maybe even a used one. I updated recently and will keep my old one just for Tech2.

I still can't get over buying a computer to fix a clutch switch!?!?! How about I just bypass the switch . . . maybe bypass the whole wiring system?
I've got a battery, a starter and a fuel pump. Just add some wires, maybe even use the factory relays, and I'm there. No?

Let's back up a second. How can I test the switch. I can't seem to get continuity thru it on any position.

Go through the circuit testing and component testing that I posted above. I would do it in that order but you can jump to the component testing.

Ok, thanks. That will get me started. I'll see if my scan tool can get that info. If not, I'll try with my multi-meter . . . tomorrow.

 

[Lndshrk Steve]

Ok. I think I have a plan of attack. I tested a few things today. Some were good, some were not.
I'm working of wiring information someone posted. "Vehicle>Power and Ground Distribution>Fuse Block>Diagrams>Connector Views" from a 2006 2.0 SC. It's a little different than my 2008 2.2LS.
Does anyone have this info for the 2008? My plan is to check and fix as much as I can and then call a GM tech in. The mechanic where I broke down my donor is pretty good with this stuff. I just want to check and correct as much as I can before I bring him in.
As usual, thank you to everyone who has offered help and support!

I can get it from the 2010 manual which "should" be the same for the 2008-2010 this evening. If you want to speed up the process you might consider an alldata subscription.

Thanks, I'll look into that.

Fuse block connectors

Thank you. A quick look shows the one ground at A6. That's the one I was missing (and I added), but it didn't fix my problem. I'll check the rest to make sure everything is correct. Thanks again!
