Pcm-no Comm????
I went to flash a tune w/EFILive,It just about started then stopped and locked up.And these are the codes I have now.PCM-NO COMM.....TCS-C1276 C.......U1255 C........BCM-U1255........BO-RFA-U1000 C.I know what they are,I have the manuals,And it keeps pointing to the serial data connector,That there's a short.And it say's to check STAR CONNECTOR ONE,Where is that?And could my PCM be toast?.I checked the battery,Its fairly new,Then took the battery out and found out why my AC did not work,Broken small black air tube
.Any way what else can I do?.................Paul. Also...REDUCED ENGINE POWER......SERVICE TRACTION SYSTEM.............SERVICE ABS.............SERVICE VEHICLE SOON.............LOW FUEL,But tank is almost full.

Hey Driver 456,
I did a google search by typing in "star connector I" and "corvette", and one result came up: it was a link to a "manual" for the LPE programmer. In this manual, they point out where this connector is.
Hope this helps.

Just for reference, the two Star connectors are located just to the left of the BCM in the passengers foot well. They are two flat connectors with little plugs that plugs into the connector that simply connect all the wires together. This is the single point that the serial buss from all devices connect together.
