Clear them all and start over. Anything that pops up more than once, start looking at.

Well, do you have symptoms first of all?

Is this something your are currently driving or is it sitting somewhere broken down?

How about a little background info. It's like walking up to a random doctor you dont know and saying "my leg hurts and its hard to breath".

I would start with checking your wiring harness.When you have this many multiple codes,in most case means a wiring harness problem,or bad connection.I have seen and read about multiple codes and it would be odd to have all those circuit go at once.It also could be a bad PCM.

Some of those codes do not even pertain to the KJ,a gas KJ at least as the 3.7 does not have a EGR.

I'd scan the codes with a better scanner to get the real codes.


Always start with the lowest # code 1st,amy resolve all the other codes in the process.

His is a '03 so what ever computer program(not a scanner) he is using is not correctly setup to read a '03 KJ.Plus the fact it does not list OEM specific codes I wouldn't trust what ever it displays,heck my $30 code puller is CAN readable and has all the OEM specific codes in it.

I can tell you by his pic it's on a PC and it's a "Global OBDII" generic code reader program,just by the terms "Mode 3/7 and so on.
