Problems with CKP relearn on 2001 12200411 PCM

[S10Wildside]

Has the code P1345 ran and passed? If the correlation is incorrect between the cam sensor and the crank sensor the learn procedure won't run. The specification is + or - 2 degrees.

For some reason P1345 was not set when I reflashed the PCM and started the engine. I had a generator code and a MIL circuit (service engine light) code P0650.

Any progress on the relearn process? Any more problems pop up?
Thanks,

I haven't touched it since I last posted. The control panel is now attached to a VW Bug engine running with a GM TBI unit. I probably won't be able to look at the engine again until Spring.

How's the bug running with a TBI? That's kool!
I built VW engines for 18 years, and I have a 59 Karhman Ghia I've been thinking about building. The dual webers might have to be replaced with a TBI.
Need more info.
Thanks,

It was a kit purchased about 8 years ago from Turbo City. It runs on a 1227747 ECM.

That's cool. I'd like to come across one of those that no one has used for a while.

I am having the exact same relearn problem on the same 12200411 PCM. What I am wondering is in post 15 Joecars' 3rd document shows that the low/rev clutch is engaged in park but not in neutral, so maybe this PCM wants to be in neutral? Just a thought. I am going to try again today in neutral. I have been over the wiring diagrams about 40 times and I don't see any mistakes on my part.

It'd be nice to resolve all these problems before I fire my truck in a couple weeks.
Good luck Lextech.

Finally got the crank relearn figured out. I did the relearn today. My 12200411 is programed as an 01 Express van 5.7-4l80e. This programming wants to see 4 inputs from the Park/Neutral switch. I grounded pin 32 and 34 of C1 Blue 80pin connector DURING the relearn, so the PCM thinks it's in park. I will properly wire it later, but my harness is all finished and tidy and I don't want to open it up any time soon. My emission test is this month. I am going to go on Monday and give it a try.

Lextech, what did you use to do the re-learn with?
Thanks,
