I have a 1336 code on my 99 vette LS1 with 02 camaro pcm code. (Crankshaft timing variation not learned) I hooked up the Tech2 and tried to do the crankshaft learn procedure. Either I'm doing it wrong or it's not working for some reason. I believe the brake input is good but not sure seeing that this motor is in a Jeep. Brake input is active high so should be ok. any ideas?
