pp1517
1516
the b's = battery voltage out of range
the U's = lost communication with XXX
the p's= trottle control module actuator position performance
the c's = tcs enabled by pcm and wheel speed sensor circuit
and b2723h = pass - key detection circuit....
1515
1120
1220
1221
1626
c1278

Something similar happened to me. Check both ends of the battery cable for proper connectivity. I had an intermittant connection to the starter from the battery and it went code crazy (of course). Felt like I was riding a bull...bucked like mad!

I hope this helps. Also I believe that PCM is not communcating with any of the BCM. It is required to have comm every 5 sec. Have some one with a Tach II check you PCM connection and you should try to clean connectors and clear codes and try again. But remember it will get worse before it get better. Also remember that if it is your PCM and you have less than 88K its covered by warranty read your owner manual.

C2105 I would reset all the codes and see if this comes back. I would pull the plugs on your PCM and also BCM. Your BCM may have failed and this would make your dash light up like a Christmas tree. The dealer will ream the crap out of you to replace it. If you take it in to the dealer maybe just have them diagnose it and then say thanks and buy the parts from Carshop.
I would do what JR said scrape all the connectors and check the battery cable. Hope you get it figured out

b2283 is "battery #1 circuit". That said, you either have a door module problem, or a wireing problem. on the passenger side. I have no other discription on this to tell you. If your not haveing problems,...just clear it and see if it comes back
b2285 is Battery #2 ...which looks like the same senerio
b2282 left door module
u1064 is nothing to worry about.
etc etc etc.
I don't think you have any major problems,..as I have seen alot of C5's with alot of codes, ....and still run trouble free.

IMO you can disregard all of the codes except the P1516 and P1517, the PCM is having a problem seeing the throttle so it's putting you in safe mode, not seeing the car I can't really go any deeper but you either have a problem with the TAC module, throttle position sensor or the wiring between the 2.

That's good advice from FFR-Z06... The car can carry a lot of codes and still run fine, but anything associated with the fly by wire throttle is a huge liability for GM and they made sure the car would not run unless this system was perfect... Hence the dreaded "reduced engine power" mode. Fix the throttle problem (don't forget to check the throttle peddle switch too) and you will be back in business...

could i just not go and buy a new throttle control motor or switch, or a new pedal switch and just be done with it???
and ive always wondered why the hell GM put a fly by wire trottle on the car and is there any way to have a cable put on instead? this just seems to me like GM planned to have multiple f'ups on the car while.
thanx for all the help!!

Can't help you with the blue and red twisted wire, but someone sent me to this thread:

I was having the same problems as you with all the codes. I just messed with one of these connectors to make it more snug. I only got one code after an hour of hard driving.
I am going to try get the local GM Vette mechanic to clean-up all the connectors for me.
Good luck.

1 of your faults is for a malfunctioning tac module[throttle control unit]the other is for the throttle motor activation.the pedal sensors tell the tac unit how far to open the throttle and then the controller opens the blade accordingly.did you suffer from "leaking battery syndrome"? if so,remove the nright front inner fender well close out.after you do,you will see the tac unit and behind that the pcm.look at the harness to make sure it isn't eaten away.if it's ok,unplug the tac unit and see if the connectors or terminals are corroded.BTW,you have already checked the fuse[s] for the tac module,correct?
either you have a blown fuse,bad connection or a tac module that took a dump.
