P0603 Internal Control Module KAM Error
 

I pulled this code with my scan gauge today. Can you tell me what it means?:-hair

Batteries were disconnected at some point. Or maybe when a chip was added to the PCM. Clear it your good to go.

That's what it was. had the batts out a couple of weeks ago. Thanks!

Working on buddies truck, got P0605 code, is that for batts disconnected too? Says ROM error instead of KAM error on the list, don't know what that means I guess.

Did some site searching, checking to see if there is a chip, and if its loose.

There was a banks chip in it, didn't seem loose, but removed it to see what happens. Dealing with a stalling issue.

Was this issue resolved?

PCM was messed up from the chip/programmer combo it had from banks. Sent it to dp tuner for a tow program to be burnt on it and all is good.
