Hello,
Ok so you have a bunch of bus communication codes mostly involving CIM and ESP. If you go to the page in the TECH 2 were you can read codes there is a BUS option that leads to a place were you can ping the various control modules on the Bus. I usually start there to see if a certain control module will not return any signal. If you look in WIS you can find the order/path through the control modules for the different buses. You will find that CIM is the gateway between the I-Bus and P-Bus. If your problem is a no start and you get it to act up you may be able to bypass the control module and see if it will start. I often do this with the ESP module because the car will start without the control module connected if you jump the wires at the harness connector. I will also note that I have had the UEC fail a few times by taking down the bus. Good Luck, Bernie
