Peugeot 407 SW 2.0 HDI 2005 - Steering Wheel Lock, Red Indicator & Stop Light, Diagbox Test

Hello, I recently have a problem with my 407 at a standstill and when the steering wheel locks up, I will add that the oil level is above the max and there is no problem with foaming oil. While driving, when the steering wheel locks, the red steering wheel indicator and STOP lights up, after which the pump stops working and there is no power assistance completely after pressing the brake pedal and releasing everything goes out and the power steering comes back. When I do 30 seconds in diagbox, the blocking pump test is gone, but when I want to see the operating parameters of the pump on a lit engine only when it starts blocking, the connection is broken. What affects the operation of the pump where to look for a fault the pump or installation itself

I recently had 307 and there was a problem with power after firing. I suggest checking the plug at the pump. Only good tug on the cables, because in my case the cover and the cable broken in the middle.

Tomorrow I will check from plug to pit and let you know how and how

in my opinion it is rather a steering gear regeneration or a new one

As this gear is what disconnects the pump

disconnects the pump so that it does not get damaged and the computer catches an error and automatically disconnects

When I start the pump test in a diagbox with the engine off, the support runs and nothing happens and so I can start 2-3 times and nothing but start the engine and start turning the steering wheel and blocking begins and sometimes it happens like a 4-5 car will pass km and nothing happens and other times just after firing

Does anyone have the wiring diagram of the control etc. of the power steering pump? or will write what is involved in the control it seems to me that the combined switches under the steering wheel can they affect the operation of the pump ??
