Repair framework Scenic

[blueangel666]

Then, I write this post not to mess up the one embossed with the attachments.

C'? an update !!

I don't have an emulator CAN, so I have to use my car to test the framework.

What burned the fuses, now ? access without having done anything, for? he struggled a bit before you turn on. In the meantime, I noticed that the
light of the passenger compartment is lowered.
I had a little bit of fear, but then the display ? access BUT has begun to beeppare, reset and give me all the mistakes possible and imaginable ( anomaly sensors, tyres, drivers, lighting, service, etc...)

It is possible that both the integrated "2843B" ???
I have not yet changed, in order not to risk destroying the tracks "as I have already? done with the first framework", but if you tell me that ? very likely to be this, to me do I replace a radiotecnico

What do you think ?? What is that built in ??

[angelo]

I think that that integrated doesn't matter, it seems to me, is a regulator makes a voltage or a switching, however, what should you do instead ? swap the eeprom of the framework the original framework that lights up regularly.
The integrated ? signed 93c56 ? below the display is the biggest

[blueangel666]

Yes, it is a voltage regulator. For this reason I thought he was the culprit.

After turning on the ignition, even if with all the anomalies ? gi? a big milestone for me. Seen that before did not give their signs of life.
But not ? usable as well.

The eeprom memory is not ? important for the ignition, if I'm not mistaken, in fact I would like to change it to last. Unless ? essential. But I don't think, I have already? tried other
paintings without problems on my machine.

New update !!!

I redid the soldering of resistors from 1 ohm to both the paintings and now light up without problems BOTH !!
But as soon as I start the engine, start the anomalies.... electrical system, airbag, power steering, service etc......

We are sure that has nothing to do with the voltage regulator ??

Or do I have to change the eeprom ? It is uncomfortable to unsolder and resolder. For this I'll keep this job for the last.

By the boys, that we are almost there, thanks to you !!!

Guys I'm about to throw in the towel !!!, I'm surrendering, I'm not having more? a peaceful life in these days

Then, this morning I did :

Exchange Mosfet and fuse --> Lights, but with anomalies (system power, airbag, power steering, etc... )
Change the EEPROM 93c56 with the original one------> continued anomalies
Campio Integrated 2843B --> continued anomalies as above
Change the 12 resistors --> Lights up, blinks, fry something (PANIC) detach the connector grey
Redo the welds at 12 resistors --> Fry and SMOKE !!!! Pi? PANIC detach the connector
Heating for a few seconds with a hair dryer hot air --> Fry and SMOKE !!!! Pi? PANIC still detach the connector

Now I don't know pi? what else to do, please help me!!!

As you said, check the capacitors. Maybe someone ? in short.

Anyway, I understand very well. I am in your same situation with the Ecu of opel to 1.7. I have 5 on the bench, but none that I can make it work.

These paintings, they send us out of the head, and some with a review on the heaters should be good to others, you can change everything will always be problems... however, the welds be careful not to let her come on top of one another

[blueangel666]

Then, before replacing the resistors gave me only errors, but not sizzled to nothing. Maybe ? possible that I had done well a few of them, now fry, BUT THE SMOKE ???

Then, it is possible that 2 on 2 give me the same errors ?? All the capacitors are bad ?? I don't think ...

The other one is still not fry, but cursed at me when I touched the resistance !! Used both, I wanted even with the errors.

The DUBIOUS origin of the paintings, I can give these problems ?? But I changed the EEPROM !!

But someone in the area of Bologna I can? help ?? Please !!

[Antonio46]

You need to proceed to steps...before you are sent up in smoke that changes you have made... check the welds and components that you have changed and you begin to go on the right way

[blueangel666]

The welds are done well enough, I wonder indeed, as I've done. The mistake I made ? was not completely clean the block from the pond above. But pu? lead to these problems ??
And I repeat, all of the errors that give me both ?? I don't think my machine is set so? evil ..... (anomaly lighting, power steering, and airbags, major)

AH..... I noticed that even when you turn off and closing the camera, the picture remains on....

[Antonio46]

C'? a short...that interfere on the can line and you from the malfunction of all the components...your car is fine... no cleaning it does nothing, the important thing is the welds that are not cold

[blueangel666]

I had no doubt that my car was okay

Antonio hears, but we're talking about short-always on the framework right ?? I would not disassemble now the machine

I have seen that the resistors that I put in are slightly different than the original. In the latter c'? written 1R0 while in the ones that I bought 1R00 "CRCW1206 Resistor T/R 0.25 W,1%,1R"
I got them on a well-known site of Italian components that you will know definitely
