New Code

I have posted in the past about my underperforming charging system. And a new code has surfaced P1638 Generator F terminal. I cleared it and it has come back in 35 miles or so. I'll pull the Alternative and have it tested this week. I hope the PCM doesn't need to be replaced as I have no way to flash my current program into new PCM. Jay
