kess v2 clone boot mode help!\

[fabiovts88]

hi all, the other day I tried to put in boot mode a bosch me 7.9.10 a 500 abarth without success
I followed the schematics me from kess v2 but nothing with both cable k4 and that with the adapter bootloader and cable
no error only when I try to read or l id ecu tells me to turn on and turn off the ignition so to 4 times without doing anything, something wrong? I soldered perfectly the resistance of 100 ohms and correctly performed all the connections , where am I wrong? she has problems with my clone? help you

[fabiovts88]

I enclose also the help

But if you've followed the schematics you should read it without problems, are you sure that your kess functions have already occurred with other cars? and if ? a clone do the change of the diode that usually solves all of the problems of reading..

[fabiovts88]

I just tried to read and write by obd port different drive to this ? the first, which I happen to do in boot mode for several reasons

[silven]

Please check that it is actually powered the unit... from the error that you seems to be a power problem...

[fabiovts88]

and but how do I find out whether or not ? fed? the two crocodiles, or terminals I have them attached to the battery and the other black clamp put to the casing of the ecu and then I ran the pinout as shown in the diagram . how could I check if the ecu is powered?

[silven]

Watch the black terminal (ground), the need to connect to pin1 of the unit... not on the carcass. I do so...
Pin 1 ground
Pin 6 and 70 12V power supply
Pin 88 Can-L
Pin 89Can-H
and, of course, the two resistors

[fabiovts88]

To pin 1 I gnd how do I connect them to the terminal? You have a screen of your link?

[fabiovts88]

silven can you help me? the crocodile black red and attack them to the battery instead of the other black where the attack? for what is not communicating with the ecu?

[silven]

I can't follow you... if you have the unit in hand... after I soldered the resistors.. you have to give the positive 12V (I use a power supply) to pin 6 and 70 of the control unit, to pin 1 of the ecu you have to give the negative of the battery or power supply all this of course with the included cables,the thing that you need to check ? if in the wires that interface with the control unit ( cables kess supplied to the pin1 you have to have the mass and the pin 6 and 70 get the 12V power supply of the battery or power supply it depends on what you use) then the pin 88 can-L and 89 can-H to the colors of the wiring of the kess you need to see the schema now can't remember them,then of course you need to follow the software when it tells you to feed the cent.
