ERROR U1064???
loss of communication with DCM, :confused:what's it mean?
also getting a P0157, something about Circut Low Voltage Bank 2 Sensor 2-B.
i've recently found that one of my FLP clamps is broken, could this be causing the error's.?

Re: ERROR U1064??? (my01zo6)
How about BCM. The modules in your Vette communicate with one another via a class 2 serial data circuit, and are monitored during operation. Each module sends a signal on the circuit every two-seconds. If a module drops out of the class 2 serial data circuit, the other module will set a DTC with an identifier. U1064 means the BCM dropped out of the circuit.
If the light goes out, and eventually the code goes away after 50 ignition cycles, then it was intermittent, and may never appear again. However, if the light stays on, or goes off and comes back with the same code, it could be a problem in the wiring or in the BCM.
P0157 means the PCM has detected the heated oxygen sensor has fallen below a predetermined voltage. I would not think a loose clamp could cause this, but I have seen stranger things in my life. Tighten the clamp and if it goes away, it fixed the problem. If not, it could be more serious.
