U0100 code came up and car is barely moving. Please help

The code means than your car can't send messages between the ECM (engine control module) and the PCM (powertrain control module).
Possible causes:
- Low battery
- CAN C bus wiring fault
- Wiring harness short
- TIPM/BCM short
- PCM power or ground
The U0100 code indicates a communication issue with the electronic control module (ECM) and the transmission control module (TCM) in your 2011 Aveo LT. This can cause the car to go into limp mode, which would explain why the car is barely moving. In limp mode, the transmission will stay in a fixed gear and the engine power may be reduced.
Here are some possible causes of the U0100 code:
Wiring issues
Failed TCM or ECM
Failed sensors
Failed battery or alternator
