C 1254 Abnormal shutdown detected
C 1275 PCM requested ETS to be disabled

PCM Code

IS your battery fully charged? Has it been disconnected? Either case will set the c1254, the other two are probably due to this code. You need to have the codes cleared with a scanner, If they comback, then it is probaly a wiring problem or a problem the the ebcm

Battery was fully charged. It happened while I was driving it. I recently had the brakes and rotors replaced. I am not sure if that would cause the issue or not.

Have the codes cleared, if it comes back, some further testing with the ebcm will be needed.

The codes have not gone away. We did not try clearing them and running it again though. As hard as it is changing gears I am afraid it may ust the joints or break the motor mounts.

Not sure what to tell you other than what I just said, that you didn't do.

We could talk hockey :)
