dgk1 Posted August 9, 2014 Share Posted August 9, 2014 I have a 2004 cx 613. It started running rough yesterday like a fuel problem. When I checked it, had 8-3,8-4,8-5, and 8-6 codes. I cut it off and started it back up and had 1-3 and 2-7 code. Checked connections on computer and wire harness. Started back up idled rough and had 9-2 and 6-4 code. It cut off on its own and won't start back now. Shows a 6-4 code when you turn the key on.

wheeler73 Posted August 9, 2014 Share Posted August 9, 2014 Check the connections to the fuse panel under the hood and all power and ground connections.

Eastcoastdiesel Posted August 13, 2014 Share Posted August 13, 2014 Having this same problem as we speak. 9-2 and 6-4. Shut off, no start just turns over like a turd. I'm really getting sick of these trucks breaking down! Keep me updated will you? I am at wits end!Sent from my iPhone using Tapatalk Quote Link to comment https://www.bigmacktrucks.com/topic/36630-6-4-code-on-2004-cx-613/#findComment-255894 Share on other sites More sharing options...
wheeler73 Posted August 17, 2014 Share Posted August 17, 2014 Could be a bad module. Unplug the abs module first and see if the code goes away. It helps if you know someone with good eecu and vecu that you can try. Have see those go bad quite often. Also could be a bad J1939 wire or connection at the engine harness to trans harness connector.

dgk1 Posted August 23, 2014 Author Share Posted August 23, 2014 Ended up being the plug on one of the wire harnesses. Quote Link to comment https://www.bigmacktrucks.com/topic/36630-6-4-code-on-2004-cx-613/#findComment-257022 Share on other sites More sharing options...
