4 months ago I bought a 2009 Prius with 148,000 miles, everything was going great, it never failed me until a week ago when I stopped at a red light the gear shift position indicator lights started flashing and the engine wouldn't start, the scanner gave me an error code U0293, it has already been checked by 3 mechanics supposedly specialists in hybrids, but they could not detect the fault, they have checked the hybrid battery and it is fine, they changed the computers, checked the fuses and cannot find the fault, I do not know what to do, someone who has had the same problem; below is the image of the dashboard
Read up on here on how to check and clear the blink codes... Unless the mechanics already did that. Next thing would be damaged wiring somewhere that has yet to be located.
Thank you very much for your answers, something I forgot to mention is that the transmission was in neutral because just pushing the car and it moves.
If it is really a comm failure, a good hybrid mechanic would have detected one or more computers offline unless it was so bad the obd2 diagnostic connection did not work. It would be useful to get details on what they saw and what they did with specifics like codes and which computers and parts were changed. One of the first things even a casual diy'er would have done is check the 12v battery with a voltmeter (hopefully 11.8v or better with the lights on) and second, tested the capacity with a battery load tester. You want those basic 12v battery results one way or the other. They can be obtained free by taking the 12v battery to an auto supply. Fuses and relays can be the cause. The 20A HEV and 15A AM2 fuses or the IGCT and IG2 relays are suspect. Again, did they check them? The fact that they changed computers indicates one or more of them were offline. "Firing the parts cannon" (blindly changing parts hoping one solves the problem) usually means they were not the best hybrid diagnosticians, which is common. A downside of the parts cannon is good original parts could have been replaced with a bad junkyard part. This can result in two problems when you started with one issue. Hopefully they gave you the original parts or reinstalled them after the swap failed to change things. If it's really a wiring problem, there are very few techs who can trace it down and repair it. Often those ace techs use advanced tools and techniques, sometimes repairing a wiring issue with "no parts required". Normally dealers will want to change the whole wiring harness impacting the area of failure. Check the 12v battery or get assurances voltage and load testing passed. Obtain previous diagnostic results and activities so the next guy knows which parts were changed. If Hybridpit was not one of the previous shops consider towing it to them or ask them for a referral to a top diagnostician.
I've been reading a lot of reviews about hybrid pits, and they have a very good reputation. I think I'll take him there.
Your spanish translation may have a serious error and a few others that are not quite right. Do not connect the 12v battery to a power outlet! Use a battery load tester! The original was referencing dealers (eg Toyota Dealers), not distributors.
I don't see the "ready" sign on the display. The hybrid system hasn't turned on, so you need to start searching from there. A failed hybrid part test is accompanied by error codes. If you do not see them, then you need another scanner that reads hybrid part errors. https://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/repair%20manual/04pruisr/05/2054m/ciu0293.pdf
