Red Triangle no code

Hai folks. Recently, the red triangle of death showed up while driving, it did nothing and sometimes it disappear and other times reappear. Many said it is the inverter pump but i noticed it works just fine and oil is not low. I had obd2 and managed to get these codes but I don't think any of them has something to do with that. Some mechanic told me that there might me some water that went inside of the vehicle compartment that caused this issue, and that is why the triangle is disappearing and reappearing. Anyone got any ideas?. And I don't have a catalytic invert and my abs is almost dead.

Here are the codes
