Lexus Rx 400h check hybrid system/VSC system

[Cpt.Pix]

Hi guys,driving today through Bulgaria the car encountered an error on the display that said "check hybrid system and VSC system" after that the car lost all power and didn't accelerate anymore.I parked in a gas station and disconnected the Battery for a reset.All went good after that for a bit but still I decided to buy a new 12v Battery.

After another 400 km those warnings appeared again but this time without the power loss.

2 months ago the same warnings appeared and I got a tester to read the codes

There was only one code which was p2601.

Also the Battery seems to be in perfect condition.

With almost full Battery the AC on full blast+headlights on goes for around 10 minutes

Is P2601 to do with the electric inverter coolant pump?

[Cpt.Pix]

It may be related to.Any thoughts?Could it may be a problem with the fuse or with the coolant pump?

[adrian-gregory]

I read that it is to do with the coolant pump. Perhaps Techstream can reveal more?

So yeah,i;ve replaced the auxiliary water pump and droved it for about 1200 km.Unfortunetately the error appeared again.And i paid like 150e for it from a hybrid service in Thessaloniki.The service was 400e in total.Maybe it's not the pump but something else,idk.
