Citroen C5 - Running Suspension Pump on Table: Connection Diagram Inquiry

Hello
Gentlemen, can you run the suspension pump on the table or do you need can? Does anyone have a connection diagram for this pump?

greetings.

You are dealing with the "Hydroactive 3+" hydraulic system

Yes, I would like to start the pump motor itself ..

I will also join the topic of how to start the pump in order not to burn the pump at my own request and to check if it is running for a short time. Where to connect what?

The pump motor has no direct power supply - it is controlled by electronics:

Maybe you can tell me otherwise, this is a picture taken from YouTube of the user "I'll be doing" under the title "Citroen suspension pump why does it burn the fuse?" check as soon as possible without undressing or working? The methodology by short-term commissioning without fear of burning.
Well, I think I've exhausted the question. Mine is unresponsive and I wanted to plug in a direct plug and check it. I don't know if the YouTube link goes here so I preferred to write it.

I wanted to add, today I checked the fuses, they are operational, the largest ones are also under the hood, they are even lower and also functional. So there was a rear and front sensor and the pump. The front sensor is 51 kOhm 1-2 pin and the 1-3 pin is 400 kOhm as if what.

Have you managed to get the pump working briefly?

>>16701917 You can turn on pump motor by powering big connector and apply (for turn on) + on small pin (small connector 2V NR). For testing also hydraulic pressure is a little bit complicated because you have to do some connection on BHI connector for actuate suspension electrovalves.

I didn't try it briefly because I gave a lot of money for the pump and I didn't want to burn it at the outset. And it's secured - it's waiting because I'm in the process of changing flats.
As soon as I move, I won't be dependent on the operation of the car. I will then present everything to you here, along with the explosion .

I short-circuited the motor itself with wires directly from the battery and did not burn it out. In the beginning the pump also blew the 40A fuse once in a while. In the course of time it also started to run noisily, until after a while it died. I replaced it with a used one and checked the broken motor out of curiosity to see what was in it. As I noticed, the biggest problem is with the brushes in these motors. Under the influence of the heat generated, the brush guides bend and go outside the commutator, it looks like the brushes wear half on the commutator and the other part is outside the commutator. The worst thing is that you can't buy such ready-made replacement kits anywhere. With my own method I corrected the condition of the guides, aligned the brushes and cleaned the commutator. After these steps, I powered it directly from the battery with electricity and started this motor. I made a few attempts and it ran without problems each time, so it will be up for a swap. I haven't dismantled the pump itself yet.

Hi everyone,
I’ve got a problem with the suspension – the pump. It was physically dead, so I bought another one from a ‘scammer’ on Allegro, then another one which was also faulty. Finally, the third pump I bought is working. After fitting it to the car, the ‘Suspension faulty’ message is still there all the time and it isn’t visible at all on the diagnostic box; it shows ‘no connection to sensor or pump’. It started like this.
I was using the car as normal when, one day, I got in and, after starting it, raised the front suspension by one level; nothing happened, and after a while it jerked upwards. I went for a drive and found that the front had dropped, making it difficult to drive onto my property. I started cleaning the front sensor, adjusted it, but nothing changed. Overnight, the car returned to its normal position. I drove into town; on the way back, the light came on at 90 km/h and the front end dropped. I thought the sensor was faulty and ordered a replacement. It’s been dead ever since. My pump’s rotor’s burnt out and it’s completely silent. I fitted a working pump and it’s still silent. There’s voltage at the relay and the connector; 5 V is reaching the front sensor. I’ve got 12 V at the pump housing. There’s now a problem with the central locking system – it forgets the keys after a few minutes, and the auto-lock feature after setting off isn’t working. After turning the ignition to ‘off’ and removing the key, everything still works.
I switched off Economy mode, and the central locking started working. I can’t adjust the suspension stiffness; it’s as if the function isn’t in the control unit. It used to work despite the pump being dead. I’m at my wits’ end.

The whole unit, or just the motor?

Did it connect before? Many Chinese counterfeits have problems communicating with the suspension due to missing components.

Economy mode switches off automatically after starting the engine and allowing it to run for a sufficient length of time.

The motor burnt out. I’ve now got the pump up and running; I had four in total and managed to put one back together in very good condition, and another one that’s working. Both are on the same controllers. There was no voltage at the excitation connector; it turned out there was no contact there due to a loose connector, so I ran a separate cable and it started working. It inflated the rear and gently raised the front. When I connect the height sensor to the cable, it immediately detects an error and stops working. I have quite a few of them, so I connected another one directly to the terminal block and the pump started straight away. I’ve found my first sensor and will be fitting it shortly. It was a two-day battle, from morning until late evening, and I think I had to take the pump apart about four times. I’m putting everything back together using the original parts after checking them.

Not quite… I thought I was going to lose my mind, and then it finally dawned on me that I’d been checking the fuses.
One had been fitted by the garage, not the customer; after moving the jumper, the key started working and everything electrical returned to normal. Nobody had mentioned anything about that jumper at all; they were just looking for made-up problems. I’d even been told to replace the BMI, but I didn’t give up and kept looking for a solution. You only get miracles like that at Cytryna:)

That jumper isn’t for switching off economy mode. It changes the way a whole host of components operate. And it’s not ‘service’ but PARK.
