2015 hybrid switches to engine right after I start driving, and lights up warning to check hybrid system. Car was sitting dead with small battery damaged and shortened. Large battery show 70% charge and does drive but for just few feet befor it kicks in into engine. Where do I look for problems? Thanks
welcome! you have to get a prius specific code reader. dealer, good hybrid shoppe, or yourself from amazon.
regular will read some major codes, but not minor. you can try that first to see what it comes up with. if no luck, you need tech stream software, on something like the mini vci and a laptop.
To clarify: the 12 volt battery was dead and was replaced? And now, starting the car, with a cold engine, the engine turns on and runs within a few seconds of starting? Does it turn off for periods, later, when the car's warmed up? Say when you're stopped at traffic lights, or coasting? That would be normal behavior.
New battery. Engine starts few seconds after and nothing happens, I just drive with warning lights allover. Obd2 reader said pump for inverter is having issues. Car was hit in the front as well and area around pump is smooshed. I suspect pinched hose restricting the coolant causing system to turn off and go to motor instead.
already have made my assumptions. Pump cools inverter. If inverter fails to get the water flow, it turns off and kicks in the engine instead so it does not overheat. That explains why it only runs on the electric motor for a brief minute. Funny thing: I purchased hybrid specific bluetooth OBD2 reader "tachyon H1" It retrieved one code. It only worked on the phone but did not work on the PC windows 10. The funny part about that is, my old hand held OBD2 scanner that does not support carts past 2009, was able to get 7 code records. The only advantage of the tachyon H1 was it was giving me each battery cell voltage. So my question now is: 2 cells are 0V and 1 cell has 51V (or something like that) instead of 15V like the rest. Why is that ?
