EDC17C46 -damaged ,help need

[szantis]

I have bricked ECU. One of the elements was broken. Can smb give me answer about this? Is this smd resistor ( blue color)? One of connectors leave and omometer take me 4,5 Mega OHM. Cars don't start ,and after few seconds fan starts only.
Pictures in attach.

Take a picture of the damaged board.

hi! this is no problem,
in your workshop lok for adere old electronic and take it out...

[szantis]

Yes its true. But I don'n have any ECU with Tricore 1767 ..now.

[exe123]

Your ECU is stuck in boot-mode. Try 1K or 4,7K resistor. This is a pull-up resistor.

[szantis]

I think not. Rather this corrupt element. I started the car after changing the soft. Then I wanted to improve .....and was damaged this element

[exe123]

This element (resistor) is connected to P0L0.6 which is needed for bootmode. replace broken one with any 1K or 4.7K resistor and try.
Fan is running means ECU software is not starting! Bad flash or ECU stuck in bootmode. As you damaged resistor I'm sure it is stuck in bootmode.

[szantis]

There was no programming between the start up of the car and the failure of the element. Maybe the tricky part is the physical electrical connection between Tricore and the rest of electronics through this element ???

[cristi_bv]

EXE123 is right! Measure the resistor under the missing one,it shoud be the same value!

[szantis]

You are right. I asked about the value and type of item because I do not have another ECU "at hand". If I had a similar ECU there would be no topic ...

[cristi_bv]

There is something else i can't understand, exe123 spent at least 10 minutes to study the datasheet for that processor so he can give you a good advice,why dont you spend 2 sec to push the thanks button?

[szantis]

On Monday I will start testing. After the tests I will know if the car has started.
Thank you for your interest.

There is another thing i can't understand, why people loose his time with a member registered in 2010, with only 32 posts, and his atritude after receive super good advice.

[szantis]

In my country there is a saying "talking is silver and silence is gold".To..... "morgano" you have not added anything to the thread, but you've added an extra post from which you are probably proud.
I do not know you, you do not know me, but you judge.

To all interested, this unit has not moved with a 1 K resistor and 4.7 k. I bought another ecu type edc17c46, de-soldered resistor, has a value of 2.67kohm ..

I greet those who wanted to help in this case.

Did the old ecu start with 2.67kohm?
