GMC JIMMY TOOL PROBLEM

2005 GMC Jimmy • 10,000 miles

I am getting code 1301 on BCM module. And no start after it has been driven for a couple or hours but starts up in the mornings of after it sits for a couple of hours. No security light on or steady. It will start after 10m min relearn. Is it the wireing or the BCM module that is more likely the cause.

This is low voltage going between circuits and module are not communicating with each other. You really need a pro type scan tool to see what is going on it could be a wiring problem or it cold be something else like shorting out.
