The dealer didn’t find what’s wrong with my prius

Yes! The relays seems to be working perfectly.

 

I think our responses kinda look lime a waste of time here.

Several PC members and I have e asked you to get someone competent to fix that car, or take it to another dealership. You just not helping matters dude.

My responses might be harsh, but I think that's what it is.

 

There are people who specialize in troubleshooting automotive electrical problems. A lot of independent garage owners use their services because even they don't have the expertise to find what is wrong. They pay these mobile technicians and then once they know what is wrong then they can fix the car. Some dealerships just don't have people who are good at troubleshooting. You might try locating someone in your area.

Thanks, @Tideland Prius. At least they are all in one place, even if there's no way to get them in chronological order.

It's becoming increasingly obvious that the OP doesn't have the background knowledge to even understand the answers to his questions and will never resolve the issue without taking it to a qualified shop.

 

Jerry, I see that a lot here where people don't have the knowledge or money to make expensive repairs and they really need their cars the next day to go to work and I really feel for them.

A lot of good mechanics aren't electricians either, that is the problem when you go to your local dealer and become parts changers.

 

There's been no progression from the OPs end even after a lot of helpful info and support, I can see this thread closed.

 

frustrating

 

“Loss of communication” is a generic term. It means two or more of the car’s computer modules (electronic control units, ECUs) that were designed to communicate over a CAN or LIN bus were not able to do so. This could be caused by a problem with one or both of the ECUs involved or with a wire or connector.

If there is a problem with the steering angle sensor or its wiring, then ECUs like the skid control ECU could report diagnostic trouble code U0126, Lost Communication with Steering Angle Sensor Module.

There are, of course, many other loss of communication problems that don’t involve the steering angle sensor at all. For example, if the engine control module (ECM) were unable to communicate with the hybrid vehicle ECU, then the ECM could report DTC U0293, Lost Communication with HV ECU.

 

Just crash it into a guardrail and have it totaled!

 

check the inverter pump.
