This is a real mish-mash of codes. The U1000 and U1001 codes are most likely causing all the others. The codes all indicate that the ECM cannot read the data from some sensor, such as the throttle position sensor, the valve timing unit (IVT), the MAF and others
U1000 CAN COMMUNICATION LINE
ECM cannot communicate to other control units.
U1001 CAN COMMUNICATION LINE
ECM cannot communicate for more than the specified time.
Whether the ECM is bad or not is hard to say. It may be a wiring problem. Cars that sit for extended amounts of time sometimes get invaded by mice or squirrels that nest in the wires and chew on them.
