Seat Ibiza iv - No power steering, no communication with the TRW pump

Hello, I recently bought a Seat Ibiza 6j, it had bullets and no support. After the ignition, the assistance lamp lights and the assistance does not work at all. Before the exchange of Airbags, Launch did not want to connect with support at all, I thought it might crash the date. But after repair, there is still no communication with assistance. Two plugs connect one to the pump, and there is voltage over 12V. So it's okay, in the second plug is plus after ignition, there is also voltage 12v (after turning the ignition), on the line Can is 2.2va on the second 2.6v under firing. I checked the cables and they are fine. There is one more plug on the pump but it is blind. My pump is TRW 6R0423156B. Is there a driver in this pump? Is it somewhere else? The only thing that comes to mind is that the pump just ...

Of course there is a driver. You wrote yourself that the CAN bus is coming.
It is worth checking the power supply with a light bulb to simulate the load.
But from what you write, it looks like you have a pump.

I checked the power supply of the H7 bulb, and everything is okay. So that's not it. And this difference in voltage on the CAN bus should it be? And one more question, the pump usually comes with a third plug from the turning sensor, in my pump it is simply blinded. So where is the turning sensor going?

Because the CAN bus should be checked with an oscilloscope, then you would know where the discrepancy is coming from
I can think, but the torque sensor is at the mangle and the steering angle sensor is on the column closer to the steering wheel.

The power supply looks ok. The steer sensor is in the mangle at the top of the distributor.
Try to connect the tester with the pump, but previously unplug the main power plug from this two-pin pump. For sure, check the fuses.
In these pumps, most types of mosfets burn from excessive overload, the more the car is after the bell

I can not connect with the controller from the pump at all, we have tried several times and nothing. Launch shows that there is some mistake (or just shows that he could not connect) on support but it can not be connected to it. The control lamp lights up under the ignition, on the ignition it normally goes out, unless I disconnect the plug, what is the power supply after ignition and can, then the error starts to glow even on the ignition. The fuses have already been checked several times, and the one at the battery and the one in the cabin and are okay. Besides, I checked the power supply at the pump. And from what I have read, even if the steering sensor was released, the pump should switch on ... So, what is the most likely pump?

The steering wheel info pump gets cut off from esp.

You checked the presence of voltage and not the power supply.

What are the errors in other drivers? is the lack of communication?
It would be good to hook up with something dedicated, eg VCDS.
Check the power supply under load because the voltage measurement is not reliable.

The errors are only in the assistance system and in the brake system. Of which those in the braking system could be erased, but it is impossible to "enter" them. But soon the error in the braking system returned. I also checked the power supply under the load of this bulb and it was okay.

okay

Specifically what errors? If the driver is dead, you should have in the other drivers errors in the lack of communication with the support, for example in the gateway.
It would be good to hook up with vcds, for I remember that I could not do something with a universal touch after the crash but I do not remember if it was airbag or support.

I do not know the specific mistakes because, oddly enough, the launch could not be combined with the braking system. I mean, if I took it to clear all the errors, then the nachwile error from the braking system disappeared, and with assistance he showed that there was still an error. Is it possible that the pump is throttled (ie the driver which is next to it), there is no communication with the assistance and this problem with communication in the brake system? No indicator lights off the clocks when there is a clock. the brake.

If the support interfered with the communication on the board, you would have on the board and in the gateway errors of all controllers on the given line from the assistance and the abs pump starting. Podplnij something else, considering a thousand possibilities when you do not know whether there is a fault to disable assistance in the event of an accident or the lack of communication with the pump does not lead to anything. The board indicator suggests that the pump communicates with the car and the problem is in your interface.

On Monday I will have the same second support pump for the drink, so we'll see what will happen.

I have one more question: if I have a second test pump, I can only change the electric cubes, and pour the liquid over the pump and gently touch the wires of the maglownik? I'm just asking if the pump will start, because I do not want to make a job ...

I see some inconsistencies in your statements.

on the Can line is 2.2va on the second 2.6v under firing.

And how and where did you check? On the plug fastened to the pump or unplugged? Can the pump come out of the pump? On the unplugged plug Can is (from the side of the car)? I have the impression that the CAN is operational while the pump or its power supply has been lost. The H7 bulb is too small a load to check the pump's power supply. A minimum of two H4 bulbs with all filaments connected.

I checked after firing the car on the unplugged plug from the power steering pump. And with this lack of communication and error it is that the launch show that there is some error on support (or simply can not connect with it), and when you want to enter the support system, I show that it can not connect with it. And in my opinion this error is caused by a lack of communication. I will check it today with two light bulbs, as you say. And what about checking the second pump that got to the test, is the ability to check it without full hooking, as I wrote a post above?
Added after 4 [hours] 41 [minutes]:
I checked with two H4 bulbs and it seems okay. When I turn on the bulb, the voltage on the plug is good over 12v, on the off engine. On fire even more.

Problem solved - the pump was to blame. Thank you all for your help!

Hello. I got to repair Ibiza 1.4 2010 for support. The situation is the same as in the case of a colleague above. I got the car from a mechanic who inserted a new pump (not a stimulant) because the old man apparently stopped working. He put in a new one and unfortunately the steering wheel lights on the board. Support is but harder. The pump is heard underneath. I connected KTS, CDIF, VAGA and ABS / ESP without mma errors, and the light is on. And I have a question, is it normal that I can not enter the AID system (44) with any tester? Maybe the assistance system is handled here by ABS / ESP? Check if the steering angle sensor is adopted, it is possible in the ABS / ESP in channel 060 and there it shows me that it is OK. I read on one of the pages that channel 44 does not always have to be active depends on the type of support system. I plugged the plug into the old broken pump and I can not get in the support (44), and there is only one error in the ABS / ESP "G85 steering angle sensor". I do not know what to do next? Is it possible that the CAN for the pump plug is released?

Nobody will help?

Oh mechanics !!!!!!!
Cables on needlap or at the bottom, colleague and cubes check corrode from water
100% and go to that and give money to the pump for a man because he is good

The answer for Maniautka's seer 27.
First of all, this fault occurs in cars of a similar class of different brands and this does not mean that if you have solved your problem in your car in such a way, it will be identical for me. Of course, every hint is worth its weight in gold, but sneering "Oh mechanics ..." testifies to small wiseral ... Unfortunately, in my case the problem was something else, no bones or cables on the shaft, etc. Maybe for you it will be another reason for wisralingu as you read my solution to the problem, but for other colleagues from the electrode probably will be useful information. I found a similar case in one of the posts here on the electrode and it was not about Seat, but Skoda Fabia. There, my friends did not stay silent like here. They gave hints, which, despite attempts, did not help. When I dealt with the problem, I described what helped and thanked everyone.
Here for you I will paste the answer from that post especially for you, maybe someone will need it. And I greet you warmly Mańku 27.?

Problem solved. VCDS connected but original. Previously, I tried Chinese and sneezed. The old 6R0 423 156 B pump has been connected and I have read the coding 11211. The new pump had the same numbers with the letter C and the coding the other. Maybe the difference in the letters says where the steering angle sensor is. In my case, the transmission did not have any sensors. In the power steering pump one cube is factory blinded. In the new pump I entered the coding as it was in the old one and it went. Everything is flashing the steering wheel on the meter went out. Thank you for help
PS in the old pump did not go to erase the error of the steering angle sensor .... so there is no question of donating the customer ...
