Intermittent debug

[Bob Burd]

Sorry for the longish post. I have intermittent warnings that pop up, including service electronic throttle control, service shifter, service axles, and disconnect swaybar unavailable. Possibly others. Been going on for years but getting worse. My best guess is there's an intermittent open or short. The swaybar one comes up most often so i tried disconnecting the connector at the swaybar to see if that helped. It didn't. After thinking more, this would find an open but not a short. A better way to isolate the problem might be to disconnect the various modules on the canbus blocks behind the glovebox. Is there a physical diagram of where modules are plugged into the two blocks? And is this a stupid way to debug? I'm an EE but I know nothing about proper canbus debug.
