I installed a PCM, and I did these steps to get car running (require steps 1-3 minimum to run):
1. do full flash to PCM;
2. write VIN to PCM using scantool;
3. VATS relink PCM to BCM using tunetool;
4. make sure engine starts and runs properly;
5. do CASE relearn;
6. write oil remaining life to PCM using scantool;
Are there any other things that need to be done...?
What about BCC...?
Further question: does VATS relink write the BCM's serial number (or something) into the PCM (how does it work)...?
