Thumbs down canbus piles up like lemmings walking off a cliff...news at 11.

U2100 canbuss off
U0100 lost comm w/ecm pcm a
U0140 lost comm w/bcm
u0101 lost comm w/tcm
u0121 lost comm w/abs

last week was a coolant sensor glitch that is currently unresolved.
even tho the DIC coolant temp showed "___",
dic showed ac off due to high eng temp. (bogus, as cluster gauge showed no temp, but oil temp gauge showed normal. after dropping it off, MIL came on showing coolant sensor code.

and just before parking it last year, it had throttle position codes (pedal and throttle body).
and car went into limp mode several times.
glad i bought extended warranty to keep up on cars electrical.

can it be a sensor as simple as coolant temp not responding to pcm pings?
all these codes are usually within a block or 2 driving from startup.
ive looked over my grounds and checked battery terminals.
checked for harness rubbings but couldnt find any.
2010 with a whopping 12,500 kms.

Usually, with multiple CAN problems, you find out what is talking, and that is the culprit. If the glitch doesn't last long enough to interogate all of the modules, you are going to be in for a long road. Good luck.
