What does the U0001 transmition code means? - 2010 Chevrolet Aveo

this link should help Service Manual2008 Aveo Diagnostic Trouble Code DTC U0001

that is the circuit that connects all of the mini computers together in the vehicle
normally it is the wiring with loose connections , corroded pins , bad grounds

code U0100 refers to a control area network(CAN bus) problem some where in the CAN bus network an electrical connector , wiring harness, , module has failed or a computer has crashed
The code appears when there is a serious situation where the signals between the electronic control module (ECM) or the power train module (PCM) or a particular module has been lost
It is not a common problem and is most likely a failure in the ECM or the PCM or the transmission control module (TCM)
bent or pushed out pins , loose ground ro the computer or jumping a dead battery or crossing the terminals while jumping will destroy a computer
code U0001is the high speed communication (CAN bus ) between modules . can be from bad connections , loose wires , disconnect battery , dead battery or wrong jumper application a good scan tool will detect any faulty control modules so use it to find and fix the faulty module or wiring

Can bus C is a serial data communication network that certain modules talk ,share information on ! There can be two or even three different bus networks - A , B , C . One being faster in speed of data transfer then the other ! There are two wire data bus's an single wire ones ! CAN- Controller Area Network is a two wire bus an the wires are twisted together to shield from noise interference . You code U0001 is a communication problem on the bus , a module isn't communicating ! How to Diagnose Controller Area Network CAN This is something best left to a trained technician !

Where are you getting these codes, they have to be fictitious or ghost codes.

U0001 is set when there is a communication problem on the high speed can bus network . The ABS module sets this code. There are computers in the car that talk over a network and get information from other modules. The ABS module at one time did not get the information it need or there is no communication all the time.
