Have a 2003 z06 with electrical issues.

Was driving got reduce power, low fuel, tcs, car then shuts off, Tried to restart the car a bunch of times and nothing. It turns over. I added gas to the car, checked all fuses. Still nothing, got home find the following codes.

C1276H
U1016H
U1000HC
10 PCM No Comm


Windows work and locks work. With the key on the Air automatically turns on.

Checked and cleaned grounds 101, 102, 103, 104, 105, 106

Had the battery charged and its fine.

I cleared all the codes and now I get this


58 SDM
U1000HC
U1016HC

40 BCM
1255HC

RFA 1000HC

I then disconnected the star connectors still nothing, also checked the door connections and those are fine.

Need a electrical pro or someone I can go to in the area. I'm fed up with this car and really want to enjoy it.

Thanks
Robert

Is it intermittent? or has it been acting up for a while before going completely dead on you?
I had kind of the same issues but intermittent, random codes, car turns over but does not engage etc, finally it got so bad when you turned the key to on the dash lights would just flicker and the solenoid in the fuse box in front of the battery would just click rapidly but thats when I was able to find the problem by tugging on wires under the dash.
Turned out to be my ignition switch because the clicking stopped as soon as I tugged on the harnesses that attach to it.
Take a look under the dash (you'll need to remove the center glove box, center bezel and knee pad) before you take it to a shop because I've read of people spending hundreds and getting nowhere.

Bill Curlee deserves a medal for making that post.

It just went dead, I took it to JRG motorsports, they stated the BCM went bad, something with a window module. Still waiting on more info.

Hmmm, you had 1 BCM code listed and a bunch of other codes.
An electrical gremlin will point just about anywhere and if JRG is just reading DIC codes they are going to waste a lot of time and money replacing parts that are not broken.
Have them look at the ignition switch if you can.
