What does the u0019 code on OBD mean?
The u0019 code is a communication failure code on the low speed bus line. You will want to have all modules scanned to see which one is not setting the same code. The module on the low speed bus that is not setting the code is the problem most likly. This particular code is indicating there is an open/short to ground or B+ on the bus line.
What does no start, multiple U1000 codes, Class 2 serial?

No check engine light. All instrument light on when first to key on the go out except battery & gauge warning light stay on.
What does it mean when your PCM says u0100?
Modules communicate back and forth on the CAN bus. Code U0100 indicates the PCM is not able to send or receive CAN communication signals. Code U0100 is typically caused by one of the following: Sometimes U0101 can pop up intermittently, or it can result from a dead battery. Clear the code and see if it returns.
