My truck has been running great. I love it for towing our horse trailer. However, last week when I tried starting it all the elctric came on but it didn't turn over. Hmmm. Did this a few time and then it showed a P2509 code. I'm not that good at electrical stuff but with this site and youtube I'm trying to figure it out before I spend a k on a new ecm. I've checked all the fuses and checked cleaned the grounds of the ecm and fan clutch. Cleaned the connections to the batteries. Seems to be working but is there a way to clear my check codes?
