Hi Kenny,

The DLC voltages were fine. The wiring diagrams were not that helpful since they did not include the high-speed circuit which all the modules the codes were indicating were on. I agree that it sounds like CAN Bus wiring or power to the individual modules. Do you also have that diagram? BTW, I am a student and was distracted from my vehicle repair by finals. Law school sucks. I've taken this vehicle to several shops and not one even looked at the CANBus wiring, even though I brought it to them specifically for that purpose. They never even downloaded the wiring diagrams-just threw it on the code reader and gave up. One side there was like 1,500 miles of wires to look at. I had pointed to the 2 CANbus wires and told him they were about 16 feet each. I really appreciate your help.

KaseKenny1 previously replied: "More then likely you have a short to ground on one of your CAN bus wires or battery feed to one of the modules." I agree. I live out in the sticks and had to had a back probe kit delivered. We then had a blizzard here, followed by my final exams, and I had to stop working on it. Now I'm back, the snow is gone, and it's time for me to get back on it.

Do you have CAN bus wiring diagrams? I'm getting codes indicating communication loss for ECM, TCM, and others, so I need the high-speed circuit showing the various modules. KaseKenny1 already sent the low speed circuit diagrams.

The DLC voltages were fine. The code is intermittent. ABS code comes on too. The previous owner installed a SnowDog plow and there are some wires under the dash not connected to anything. A wiring diagram would be greatly appreciated.
