Hey all,

Need some help, I got a mail order tuned PCM from PCMforless, and it ran great for about 3 weeks, then one day I got in the car and it wouldn't start- no crank, nothing but a SECURITY light. I thought it was a VATS problem. I pulled they key out, waited about a minute, then it started right up - no problem. The car runs fine with no issues. Then the SES light came on. I used my ELM scantool to read the code, it displayed p1336. The research i've done says I need to do a crank re-learn using EFI live, HP Tuners, or a GM dealer. The problem is that I am currently stationed in Italy and all the GM dealers here use the european OBDII and thier scanners won't read my PCM. Is there some procedure I can do, or do i have to send the PCM back to PCM for less in the mail and wait 4-5 weeks? so the cliff notes version:

- p1336 code thrown after VATS issue
- car runs fine with SES light
- No GM dealer
- Fix by mail order tune company will take 4-5 weeks.

I would really appreciate any help you can give me. Thanks!

Okay, I found out the VATS problem is in the key cylinder which I am bypassing. What can I do to fix the code though? How do I do a CASE relearn without programming tools and without a dealer?

 

You need to find a scanner that has CASE relearn capability.

Can't even send it away, because CASE identifies crank position for the PCM. Must be done in the car.
