ecu manual repair

[kentrinite]

hello all I'm looking for a repair manual for eproom ecu and I do not know if someone can advise me a manual and the site where I can have a court;)

[szkeptmen]

It would be nice :)
Search forums...

[alejuz]

I also am interested in learning to repair ECU

[delio78]

for ecu repair, you need test system
schematic for ecu
and knowledge of electronics, fuel and ignition system

best regards

[papano12]

Hi, I have a lot of knowledge from the ECU connector to the outside!

Now, I know the interior,
Recommended to read memoirs, immobilizer, BSI, I want the line PSA

thanks!

Ok,
Besides the electronics and fuel,ignition system knowledge....

Are there professional tools that can manage this job? Is there a tool that can test the ecu inputs and outputs, signals and wiring?

[ominimicu]

you need an osciloscope to detect faulty semiconductors and see how the current behaves through the ECU.

Second build an engine emulator and you might test functionality of some of the basic Ecu functions.

THe rest is just knwoledge of tipical ecu faults, nd search for damaged components or conections

[i_shot_the_sheriff]

I'm seriously thinking of starting with these stuff!
I will buy some tools and i will make DK my next home!! ;))

I can check with autodata.

schematic for ecu where to download all euc thanks

[thiburco]

need this too! schematic and ECU repair manual

Thanks!!!

Hi
To be ecu specialist you must first break it and then repair it .
Need to have knowledge of how the components works inside it and also need to have a known good wiring diagram of input and output signals.
Ossiloscope will help a lot while you test some signals and you need immo off solutions on this to test some components..

Yes and he need DATASHEET for most component's which is so hard to find especial if they industrial - not standard type ;-)

So it is like magic and ask a lot of time and special tool ... etc

I've heard there are some test benches (ECU and ABS ECU Rebuilding - ACtronics - Electronic Automotive Components (http://www.actronics.eu/en/content/43/ECU-ABS-ECU.html)) check out here!
Its a tool that can check the input and output signals of the ecus!

nobody have ecu repair manual...just doit yourshelf step by step ,if you know a bit of electronics ...this mean time and hours of work,and when you done something good its better then somebody tell you how to doit...if you fail doit again...Regards...mipmf

thank you for the information but could you tell us more about building an engine emulator?

I agree with you my friend ... since nobody wants to help the other .... is good to help our knowledge and know .. some point everybody will need help and then you need someone to help us:party:

[PierreTheron]

I think we would need something like this as well..


Automobile Sensor Signal Simulation Tool MST-9000 (http://www.greebid.com/wholesale/automobile-sensor-signal-simulation-tool-mst.html)

This will help a lot if it does what it says.

[placido]

for beginers like me where would we start, i think our bes way to start is understanding how components work then be able to identify, eproms, immo, etc then move on

[kaToo]

Placido is right
And for beginners like me that don't know anything about electric parts , it will be very good if somebody have a list of Resistors , eeproms , etc... and a tutorial how we can test them if they are in good condition if they are working or not , this would be very good help ...

THANKS

[antwnhszr]

who have a program that shows in some way what to do when you got your hands on an ecu that shows what is the immo what is the chip that needs programming ..... and everything else must be done ... Thanks and hope to respond by all

Hi mate . Have Lost this.
Traced and trusted.Sirius 32
Ecu
Spend some valueable time on any ecu and you might fix it ?????>

If you can do it on the vehicle it might just be easier to find the fault . (It helps with the immo decoding issue))

Hi mate

you must know how all components look on ecu and what they do ,, Then only you will start to recognise them by sight only .

For the ~~~~ing moment .that is all i learned so far .
I google and Dk when i do not know what they do till i get a understanding of what they are supposed to do ..



I get plenty misses on ecu repairs . but then still i hit it spot on sometimes...

My opinion is that do you want to do a heavy job with less knowledge base. All you describing you can find in Internet. You can't describe thousends differend of parts in a few words.

[i_shot_the_sheriff]

It's true that you cant learn all that stuff at once!

The weird thing is that sometimes there are common faults in some ecus!
For example, in some Huyndai ecus you will notice that a common fault is a "burnt" capacitor!

Or on the opel hybrid ecus.... if you check inside a faulty ecu you will notice that there are some tiny "feet" (dunno how they are called :P ) that are cut! You can solder them with silver soldering and the ecu is FINE!!! ;)

Hi there

You can start by this

Megasquirt EFI Simulator Kit Photo 4 (http://www.carcraft.com/techarticles/megasquirt_efi/photo_04.html)

If you want to learn start by building your own ecu like mega squirt. After that you will have some basics to understand how they work more or less and you can pass to some with more protocols. You have to have a can analyser and some way of reproducing can packages . More recent ecu's use alot of info with can and you can't test some features without them. Design between them can be very diferent and sometimes you will be confused with what engeneers was making there. You MUST know basics about electronics, you must know how a fet works, how a logic port works, how an amp op works , how a transistor works, how a voltage regulator works, how a zenner works and so on. If you are expecting of a miracle it do not exist. Is cheaper to buy an ecu on scrap and change processor and memory than to pass hours checking components. I fixed some just for fun but i think right now is not profitable to invest on many sistems just to fix some. Of course i dream with a sistem like vector to test them but simply i will never get my money back even thinking on a market of 4 or 5 milion cars. If an ecu on scrap cost 100 euros is cheaper to put it working on car. Only time by time apear some business that would be profitable if you had made the milionare investment to cover all ecu's. Hope it helps

Best Regards

sorry my friend but not completely disagree with your opinion .... it can not buy everything, that exists from device, by software manufacturers who build that helps repair the ECU ...... but will try to help each other through every forum .... so we are all here every day, every moment ...:giveup:

[faiscamix]

Hi there

You can disagree but you will understand that for supporting your customer right on a wide range of ecu's without especialised test bench will be hard. I know it because i made it and i run away from that kind of work. Work intensive with exception of some known problems that you already have solutions. Not much information and when you are going to recieve probably customer will say that he would get a cheaper solution buying an ecu with immo off (what will be truth). I make it for fun because profit :S i almost never see it.

Best regards

my friend by Portugal ... I believe that we should strive for that we believe can bring us profit .. I'm not the best in the business but I believe I can do this work to have a d.oi jobs longer in our countries not doing well .... whenever and as you know without being specialists, you will do the impossible to manage

[antwnhszr]

Hello my friends ... I open a new issue ... when thou shalt be to plan a microchip NO IMMO .... I repeat, NOT IMMO. other microprocessor, how you doing the program; with ecusafe? with ECM? who knows our help ..

It seems nice product for starting a nice test bench for ecu's. I'm planning to start to build one test bech for dash and ecu's. Making budget now :stupid:
