Codes

Well, just replaced alternator, charged batteries, and truck is throwing 2 codes:

P0266-cylinder #2 contribution/balance
P0603-internal control module keep alive memory (kem) error.

Any ideas/suggestions? Just lear them or do I now have a serious problem. The truck wasn't throwing any codes prior to the batteries/alternator going dead, and it sat for 4 1/2 days.

Oh, and the ABS light stays on for several seconds after the truck starts now too. :shrug: :wtf:

clear them and they should go away.

Phew...Thanks man. Maybe I'm being a little paranoid...IDK. But it is SOOO nice to have my truck back!!!

i had those two once after loading a new tune and cleared them and they never came back. that was after reading threads about them thinking something was wrong

You rock man. What would I do without you? :grouphug: :blitzed:

Cleared the codes and drove around a while. No problems or codes as of yet. And the truck seems to have ALOT more power than before. I had no idea that low/dying batteries/alt would cause such a lack of power. It's like I just got it tuned for the first time.

you probably had low FICM Voltage which caused some power loss

I was worried about killing the FICM so I just let it sit until I could get it fixed. But, being as I'm still learning about diesels, I had no idea it would be that bad on them. At first, I was going at it like I would have on an old gasser. Thank God for PSA!!
