Hazard Sign with “ Check Hybrid System “ error

[pwuser151724732228]

Hello everyone,

I have a 2010 1.8 Prius just got it washed and used Diesel mixed with petrol to clean the engine bay after an hour or some it got the yellow hazard sign with the error Check Hybrid system.
What it could mean?

It could mean that you've got diesel mixed with petrol in places where such things should not be present. Perhaps dousing an area with sensitive electronics with such substances is not recommended by the manufacturer (or anyone, for that matter) for a reason.

Check for error codes using an OBD scanner to begin finding the problem.

Turned out it was some residue of humidity on hybrid inverter’s connectors. Parked my car in direct sunlight for 3-4 hours and it dried itself and warning gone.
