What is this code?
Have been chasing a slight vibration at idle for a while now. At first got no codes, but now I have a P0603 Internal control module KAM error. Does anybody know what this is? Just curious since I am taking it to the dealer for s few other warranty things and I am sure they will read this code. I just want to know what it is so I can see if it could cause the type of vibration I am feeling.

A lot of codes, including 603, will stay for a certain number of miles/key cycles even after the error goes away (ie, returned to stock). This is why its important to clear codes via a tuner, scanner or battery disconnect.
