U101 Lost Communication with TCM

I was driving through some desert roads and my brake fault and sway bar lights started to randomly turn on. After that I: stopped, turn the vehicle off, did a quick inspection and found nothing wrong. I started it back up and the two lights randomly came back on and started doing it more frequently and my dashboard started to light up. I pulled over again, this time off I-8. I remembered reading about people having problems with the Smart-Bar causing some the same symptoms. So I tried to disconnect the bar and the plug wasn't coming off very easily so I decided to cut the wires since I was going to install this soon anyway. After that I tried to start the Jeep back up but it would not do so. I could turn the ignition to start and the engine would turn over but not actually start. I then plugged my OBDII reader in and this was the code it pulled out. I eventually got back home and looked up what my service manual had to say about this. One of the listed causes was an open or short in the CAN. Was I just that much of a dumb-ass and acted too quickly? Should I have waited until I got home to disconnect the Smart-Bar? If I disable the Smart-Bar with my calibration module would this problem disappear?Any experience or help with this problem is greatly appreciated.

Mechanically sound, electrically ground...

And it turns out the culprit was heavily damaged buswork in the TIPM. At least I have two thousand miles left on my warranty. Who else has dealt with a broken TIPM?
