magneti marelli iaw 4ev.ar some help needed pleas

[patrickmk3]

hello,

i try to delete some dtc's from this ecu magneti marelli 4ev.ar
i have fgtech kess and ktag and im608 and programmers like orange, xprog upa and stuff like that.
but i try to read this ecu with fgtech bootmode st10f280
i made connections as follow
pin 1 and 2 ground
pin 4 and 15 plus
and pin 29 k-line

is there any resistor i need to place on the board or something i need to remove before trying to read ?
because with those connections i made it is not working at all.

hope some one can help me in the right way

greetings patrick

is this for 1.4 BKR engine
if so your ecu connection is wrong
+ve pin 27 , 15 , 4 ( pin 27 is the output of ecu current supply relay )
-ve pin 2 , 28
k-line pin 29

Put a picture with ecu board. And tell us what eep is inside. 95320?

hi yes my friend 1.4 bkr engine

i will post a picture soon as possible at the moment i dont have the car here.
i ask already for the car to come so will be today soon

[patrickmk3]

here are the pictures of the board

[patrickmk3]

anybody still awake ? that can help me out pleas

This is iaw4hv pinout
Obviously, you didn't think that pin #1 needs to have power line 30...

[patrickmk3]

but the thing is i connected im608 as follow
pin 1 and 2 ground
pin 4 and 15 plus
pin 29 k-line

and than i can communicate with ecu read dtc and stuff like that.
but im608 can not make full read of this ecu.

See if 2 and 28 are together at ground... find it measuring between them and a condenser minus from pcb
Pin 1 see if has a reverse diode on pcb adn if yes, that is the Plus missing... that is why you have no power for reading the file. Ktag will read it as IAW4HV if you follow the boot procedure as in my picture. Good luck

again you missing pin 27 main power for ecu and pin 28 ground , pin 1 is for o2 heater circuit according to vw elsa

but iaw4hv is the same as iaw4ev than ?

i tried it like that like you said but it didnt work my friend
+ve pin 27 , 15 , 4 ( pin 27 is the output of ecu current supply relay )
-ve pin 2 , 28
k-line pin 29

but i try to remove some dtc my friend.
the are not on the eeprom right
to read a 95320 is not a problem.
or do you need the dump for something else ?
