After controlling the same as the battery.

Thank you very much. That's what it was about. Buddy fructon you may know what should be the voltage at the pump's terminals?

ok, and how do you think, can I briefly give a hint on this pump to light up, or maybe I can burn something?

And you checked the relay? I would not try because it might be short circuit somewhere.

What short circuit? Have you looked at the diagram? Only the pump can make a mess.

The relays have been replaced, the effect is missing. On the 0V pump lines.

Hello, and the car ignited, but ... There is no relay number J49 in this pass. in the bracket under the board. The car started off after I gave the pump 2 power rigidly by removing the relay 2. The relay bracket does not receive any wires in place of relay 4 J49. The question is whether the above scheme is certainly correct. Where can the next J17 relay be located which controls the above J49. There is voltage on pin 6. On pins 10 and 8 also. Can I ask for a further diagram 98 showing power on pin 8? I can ask for diagrams

ie the relay receives a signal from ECU (J623). so if the connection to the ECU is correct, is it possible that the driver is damaged? Is it possible to emulate the signal from the controller in some simple way?

Mate, my friend fructon, can you direct me a little, Is it possible to emulate a signal from the controller in some simple way?

Repair the driver or use a different signal - from the controller

and which signal would be correct ?. Will attaching another signal leave an error? How much does it cost to repair the driver?

Hello,
patient Passat 2.0 CBAB year 2008.
error
009778 - Relay for Fuel Pump 2 (J49)
P2632 - 000 - Open Circuit - MIL ON
Freeze Frame:
Fault Status: 11100000
Fault Priority: 2
Fault Frequency: 1
Reset counter: 255

The car does not light.

I am looking for an electrical fuel system diagram, the fuel pump in the tank is working properly.
My suspicion falls on the pump below.
Does anyone know what kind of currents should be on power cords?
Is there a relay from this pump?

Start at least by trying to repair the driver. I do not personally support any ointment

Problem solved.
Lack of continuity between the T10 block and J623 pin.

Topic summary

The discussion revolves around a 2008 VW Passat B6 2.0 CBAB experiencing issues with the fuel pump control, specifically related to error codes 009778 and P2632 indicating an open circuit. The user seeks an electrical fuel system diagram and inquires about the expected voltage at the pump's terminals. Responses suggest checking the relay and power supply, with some users confirming that the pump operates at battery voltage. The user later discovers that the car can be started by directly powering the pump, indicating a potential issue with relay J49 or its connections. Ultimately, the problem is resolved by identifying a lack of continuity between the T10 block and J623 pin.
