hi. i need some ideas here. I have a 2002 with 216k miles. ran great on original battery till recently. engine started reving with little power, and codes P3006 and 3021. indicated bad battery. I noticed recently that battery did not hold much of a charge. I bought a parts car a couple of years ago, so replaced the traction battery. not too big a job. 2 1/2 hours only to remove both and switch. With the new battery, lights come on and hybrid light comes on but motor does not start and i get a P3030 code. Is there a startup procedure to initialize a replaced battery? has the donor battery been sitting too long? any ideas? much appreciated.
