I am still getting this DTC 1571. I went through the diagnostics and can't find anything wrong. Could LS1 edit have anything to do with this? Anyone run into this before?

Thanks

P1571 Traction Control System PWM Circuit No Frequency

I am not sure if that is the same code for GM, the site had it listed as a generic OBD-II code.

That is what my shop manual shows as well. I have 5volts on the line. I don't have a scope to check the frequency, but everything looks in tact unless the PCM has died! Any idea if any settings in LS1 edit can cause this?

I believe there were some discussions on how the TCS works a while back. Have you tried a search for any other topics on this subject? Even if the topics dont have the exact info you need you might be able to PM someone with a good working knowledge of the system. Just my .02 worth and sorry I can not be of any more help.
