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.

I HAVE A TOYOTA CAMRY HYBRID 2011 MODEL, PLS DOES ANYONE KNOW THE MEANING OF THESE CODES AND WHAT I CAN POSSIBLY DO TO SOLVE THEM, U0100 AND U0001


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

or
any other codes that you need help on
