ECU TESTING ! ! !

[MONTA BM]

Hi mates of this great forum i am new with you here i have question about ECU repair
1st i wanna say i learn my self about ecu programming and repair that's mean i search tutorials ; books , videos , pictures etc and then bulding informations and i aspire to become a professional in this field so without lengthening can anyone tell me how to recognize the failed systems parts
for example i have problem in ignition system or injector or throttle body....
what the testing procedures to find the failed ic or transistor


I WISH ANY ONE HAVE KNOWLEDGE HELP ME

hey members where are you ? no one working on ecu repair to help me !OR no one want to share his experience !!

you must test and test and test even when you are dreaming my friend, electronic is deep, you should know what is for every single component and learn yourself, i don,t think there is someone or someguide who can help you to learn, problems are allways different from each other, so keep looking video tutorials online

all I can say from my side is that most IC fail because of failed transistors and diodes , mmmmm but what caused the parts to fail ? there start the other questions , sometimes u can see damage but now I have a edc16 ecu with me no visible damage but no communication on can or k lines and no chips heat up , so yes it go deep , if u are lucky to find somewhere in the forum a repair guide it will help long time ago I got Bosch ecu manuals but also very basic but give u an idea what part of the ecu do what work

thank you for your respond friend
yes im learning about electronic and i know what ecu have componants , diods, transistors, capacitor , resistors, micro-processor, crystal oscillator , power supply , A/D converter , input modules , output modules , storage modules (RAM ROM FLASH) interface module (bus)...
i don't wait from people to show me the way
i will staying lear and lear and learn on myself
and sure one day will become professional and In cha2 Allah will help people like i am right now

your righ in your words
i think the ecu manuals is good idea you can give me
just question we will not talking about failed part , i want to say when i disassamble ecu cover and PCB is front how can i identify ignition ic or throttle ic ...

I got manuals from another site , but I will try and find link , but to answer u , different ecu have different ic , so best is google the ic number u suspect and see what u get , but sometimes injector driver is ic and sometimes it is transistors , so difficult to give u a straight answer , I will get stir crazy mad if u try to understand all the ecu's but google and compare working ecu with non working one , this is a specialised job and I think a lot of members here will tel u that they have been fixing ecu' s for years and still it is a chalsnge sometimes

ok i understand but don't forget to send me manuals when you find link
