    Hi all, my 2004 Prius is having some intermittent issues. What happens is I will be driving along and I will get the /!\ CEL, ABS and TRC light and the ICE will start runing, I have had this issues intermittently since Oct. before simply restarting the car would resolve the issue. Now it works only when it wants to, I have had some luck moving the wires that go into the fuse box as a tempoary fix and the issues seems to be caused by bumps in the road so my money is on something is lose are being shorted. The DTC codes are always either u0100 or u0293 or both. I have a mini VCI on the way. I have already replaced the 12v and have tested it.
