To expand a little on the day everything went to hell. I was called because the car had went from running fine to saying Engine Power Reduced and began running like crap. Then it stalled out 5 minutes later. He restarted it drove normal for a bit then the same things happened again. Which is when he called me. I got there and checked the codes and there was one for a cam shaft sensor short and google told me that could cause the engine power reduced error. So I changed that in a nearby parking lot. Cleared the codes, started it took off. The same thing happened yet again. Checked the codes again and the cam shaft sensor plus something else was bad. I cleared the codes again thinking maybe i had forgot to clear the codes. It drove for nearly and hour till we were about 20 minutes from home. It was running normally then, Engine power reduced, lot of codes for multiple things including some for sensors, transmission, timing (i think), and one with no description that i looked up to be "dealer specific code" which I believe i tracked down to something relating to the hybid ECU. This was several months ago so I am trying to recall. I probably have pictures of all the error codes somewhere.
The car would no longer run. It started, ran rough for maybe 5 seconds the shut off again. We towed it to a local tech shop that I usually use for electrical issues. They spent about 30 minutes and said it was most likely the hybrid computer or a short somewhere. The engine bay is clean and virtually oil free and the wiring in general looks great. But they were not certified to work on hybrids so we took it to the local dealership. They charged him for 5 hours of diagnostics to say the same thing and quoted 6k for a new module plus install? I think. I felt like we were getting screwed but had no way to check anything they were saying. They agreed to install a used one and program it but with no warranty because it wasn't there part. Having no other realistic option that is was he did. Then the dealership said the new module wouldn't take programing but was vague about the exact errors and then said it was shorted internally and there was nothing they could do. Returned the module and did more research which is about the time I originally landed here.
Once I found I could use Tech2, gds2 and SPS2 to do everything myself we decided to bring the car home from the dealership. Which is when we discovered the parts missing and all that nonsense. In order to lear the programs and procedures a little better I decided to put the car back together and try to reprogram it myself to see where it failed and how the software worked. Well, everything programmed without error. It did the full sequential reprogram of the hybrid module no problem.
I don't know what to do. Everyone did agree it was the module but it seams to be acting fine. The dealership said it was shot and they couldnt get a response from anything it was connected to but that simply isnt true apparently. Only the low voltage errors might be keeping it from starting. As far as I can tell none of the other errors should, they are mostly for sensors and support systems. Right now I am just trying to figure out why it wont start without just throwing money at it. More and more I am thinking about the battery but I just don't know enough about them yet
