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

[silven]

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.

[silven]

I looked now to the schematic, you can read it in the k-line with the cable k4 virtually pin 6-70 positive wires red and blue pin 1 gray negative... and pin 91 k-line green,but make sure you have as I have already? said to have the power by checking with a multimeter to the heads of the wires in grey and red and blue (I don't want that I had a problem with the wiring) once you have verified this, and you can't even Id do the ecu the problem ? in your kess.

[fabiovts88]

thanks silven Monday I try and see , I do not understand but the cable k4 has three crocodiles, one of them red and two black, the red and the black attack them, say, to the battery and the other I do not understand where to attach it? ? them my doubt.. can you make me a diagram or explain to me where to connect

[silven]

the "crocodile" black which you find to be alone (from the part of the wiring harness to the ecu..) you can put a mass on the frame unit ..but you need to check as I have already? said that it is fed to the control unit on pins 1 and mass 6 and 70 +12V.

[fabiovts88]

ok then, I had made the right.. to check this, just that I take a tester and when all the cables are attached I can see if they are 12v right? or just that I give it power from the battery to check if it comes to the current?

[silven]

You are giving power check if the red and blue cables get the +12V and gray should get the mass-

you don't have to worry if the wiring has more wires, you have to follow the pattern and the directions of the scheme that gives you the interface, you posted then you've got it, so if you had 50 wire them wanted to attack all?

[fabiovts88]

no my question was only for the black crocodile not to the other wires , if you have read all the discussion I wanted to understand if the problem to reading was the black crocodile or he was in my kess v2 , not if I had to attach all the wires having already the schema , I'll try to see if you have the cables come in from 12v to see if I messed up something or the clone is not to be

[fabiovts88]

I then checked you wire the red and blue come the 12v while the wire k line ? right that does not come with the 12v?

[silven]

I then checked you wire the red and blue come the 12v while the wire k line ? right that does not come with the 12v?

Is the wire kline and communication, now check that with the photos that I attach to put in the boot right.... and the resistors are 100 ohm ,once you have verified this and it does not work, you have problems with your kess.9134

[fabiovts88]

Schema ? just then recapping wires red blue must get 12v gray mass and the green k line no 12v right?

[silven]

On Saturday to try it I made one just with the kess, usually in the boot to do with the cock kess me feel better via the serial..***** s, I used the module in Bootloader and cable 14P600KT02 in the diagram and power the module, everything is ok, read and written without problems, check the resistors as I have already? said, long time ago with a other ecu I couldn't put it in the boot and had a resistance that was 120ohm and not communicated,and then if you haven't done it we would have to make the change of the diode to the kess for him to "digest" almost all

[fabiovts88]

Nothing I tried again today on another ecu bosch always me 7.9.10 but nothing tells me to wait for a couple of minutes and then nn is nothing

[silven]

And then I know that ? your interface has some problem... as a last resort if you haven't, try doing the edit of the "diode" to kess.

[robo]

The tricore modules of the Kess china does not all go as they should, while the Kess euro tested and it goes like gold.

[fabiovts88]

you say that the diode will act?? now I'm purchasing the ktag maybe with that I can see ? or not ?
