Remigijus Posted June 26 Share Posted June 26 (edited) Hello. I have 2007 Toyota alphard hybrid witch one have no starting problem. When you trying to start engine works for few seconds and cut off and not starting again. When I disconnecting all batteries and he stay for a while till he reset and it same again( Engine works for few seconds and cut off). A lot off lites on dashboard. I done diagnostic and I get code P3125. I know it's inverter malfunction. When I dig deeper I get sub code 496. Maybe someone know what's meen? Maybe someone have same problem? I done a lot off research and looks like everyone have different problems with same code. Maybe someone know exactly where problem can be? Water pump making noise and I think it working fine. Someone said it could be thermostat ,but how thermostat can be problem if engine is not even worming up. Edited June 26 by Remigijus Quote Link to comment Share on other sites More sharing options...

Picasso Posted June 26 Share Posted June 26 Check inverter cooling pump Quote Link to comment Share on other sites More sharing options...
Remigijus Posted June 26 Author Share Posted June 26 Inverter colling pump is working. I saw in some video it could be currents sensors or modules inside inverter,but still can't find what exactly this sub code means. Quote Link to comment Share on other sites More sharing options...
smurf Posted June 26 Share Posted June 26 I don't have P3125-496 on the list of diagnostic codes I have. I have found THIS, which points to the problem being more complex than the coolant pump sadly. You'll need to use chrome to translate it from Russian. Quote Link to comment Share on other sites More sharing options...
Remigijus Posted June 27 Author Share Posted June 27 I'm already watched Russian videos, they saying what most common problem is green module and this module is responsible for starter generator motor and they showing how to test them. I tested all modules and they are good. If is bad current sensor maybe someone know how to test them? Quote Link to comment Share on other sites More sharing options...
Jeza Posted June 27 Share Posted June 27 P3125-496 is a starter generator fault, "Load short circuit due starter motor inverter abnormality" not much help really. If DTC P3125-448 is also shown then goto related diagnosis, however I can't find what this code is. Quote Link to comment Share on other sites More sharing options...
