Ak90 pin no touch ошибка - ErrorsMaster.ru - большая энциклопедия ошибок и их решений

Problem:

I picked up an AK90+ and began the usual task of scraping the board coating off the 2L86D chip. It can read the key but cannot read the EWS.

Have any of you guys ever had any trouble reading EWS 3 with the AK90? I cleaned the pins properly and also pry out the pins on the connect but still get “pin no touch” error. Will the K-Line adaptor make a difference?

Updated:

I’ve tried a few different packages, removed the software and the silicone drivers, rebooted my computers in between, plugged the unit in, then installed the software, tried turning the chip cable connection each direction and tried a minimum of 20 reads each direction with varying levels of pressure on the main chip, pulled the pins on the reader out a bit thinking they were pressed in too far (on the cable), just about everything. All I get is still “pin no touch”. Any idea?

Solution:

If you have the ‘Pin no touch’ error, that means that the program is communicating with the AK90 properly. You can verify that by seeing if the AK90 can read a key.

The problem is likely that pins haven’t been cleaned where the socket contacts them (or you have selected the wrong module version, or have the orientation wrong, or the cable isn’t plugged in).

Seems like some people get it to work easily and others have to fight it to the death.

Here obdii365.com engineer provides some possible solutions. If one doesn’t work, try another instead.

1).

Best to uninstall everything if the unit wasn’t plugged in before install the first time. There’s no down side and it only takes a minute.

Go to add remove programs in the control panel and browse there by installation date. That way you won’t miss anything.
Uninstall anything called Silicone. Then reinstall the software, but be sure to have the AK90 plugged in before you start installing the software. That is important. You must get the drivers all Uninstalled before you reinstall them properly with the unit plugged in. Also, you have to rotate the plug 90° counter clockwise. The arrow and the dot did not match up.

2).

Worked.

I had to remove all the software including the drivers with add/remove programs. Anything to do with it, anything named silicon I think it was. Then I plugged the AK 90 in to the one port that worked and then reloaded the software from the disk with the AK90 key programmer plugged in. Then followed the instructions to right click on the new desktop icon and load the drivers. Then I had to try the cable in all 4 directions and the dot and arrow did not line up, but on the 4th direction try it worked to read the ews.

3).

Worked.

When I had that issue, all I had to do was rotate the ak90 connector.

4).

I went through two AK90+, a K-Line adapter, and multiple laptops while continuously getting a pin no touch error. The only thing that worked for me was scrapping the chip on my spare EWS module like it owed me money (I literally had metal shavings on my desk afterword) and applying moderate pressure to the connector while it read and wrote the chip. Obviously I’m not brave enough to do this again to my stock module, but that was what it took for me.

From what I observed while messing with my EWS modules is that if the connector is incorrectly oriented or not fully seated it will fault with the Pin No Touch almost instantly, however if it’s on correctly but isn’t getting enough pressure it will take a few seconds to fault out. Once I got it not immediately faulting I just kept putting more and more pressure pushing down the connector until it worked. Again, not something I’m comfortable with repeating on my stock module, but that’s what it took to get the spare to work and reprogrammed.

5).

Make sure you have the plug clipped onto the chip the correct way.. this is indicated by lining up the dot on the plug and the dot on the chip.

Worked like a champ. I did have to use version 3.02. I also had to push the connector down on the chip while it read and write. Had to hold the transponder with my fingers. If it says pin no touch make sure the connections are clean (i used a sharp knife) and push down on the connector.

6).

Pull the white shrinking tube from the connector. Look for two PCB tracks that go to the outer pins. They are close to each other. This should be your right “top” and should match the dot of the Chip. Also push the connector all the time onto the chip.

7).

Press the adapter onto the chip and keep it pressed. Then read. Did that for about an hour eventually it worked and keep trying.

8).

I always have this problem. You have to push down chip really really hard, even with both hands.

9).

Put pressure on the clip when reading.

In Sum,

Press and hold connector (put pressure on the chip) seems to be the method with the highest success rate.

Не так давно сам пришил новые ключи с помощью программатора АК90, и по началу столкнулся с той же проблемой ( не видит чип). Дело было в отсутствии контакта между разьемом программатора и самим чипом, возможно контакты чем то покрыты. Я просто поджал рукой разьем программатора к чипу и держал пока идет программирование. Сейчас использую выкидной ключ.
Никакие провода не подпаивал. На разьеме должно быть указано расположение первой ножки чипа.
Вот к Вам и просьба прозвонить контакты на проводе — к каким ножкам на адаптере какой провод идет.
У меня либо провода перепутаны, либо один не подсоединен вообще. Т.к. всяко уже пробовал и поджимал и чистил.

Сразу не отписался, виноват. Проблему решил, немецкая недвижимость снова превратилась в движимость и продолжает меня радовать! ))
Вобщем, это китайское суперчудо (ак90) сожгло полностью мой ews, так, что ничем больше не возможно было извлечь данные из чипа. Купил аналогичный ews3 на разборе (с авто 2003гв), зашили в него мой vin, пробег, isn, отключили в нем эмуляцию ews2. Запрограммировали новые чипы для ключей, нарезали китайские болванки, привязали платы д.у. ц.з. Все собрали, синхронизировали евс-дме. Вот и все приключения )))

И так было преобретено 2 ключа и кодировщик Ak90. Кто сталкивался с проблемой pin no touch? Помогите. Контакты очистил очень хорошо. Усики на фишке подогнул и нифига он не читает ews. Только ключи новые читает и всё.

У меня как-то не наблюдалось проблем с записью ключей, но проблема может быть в самом АК90.

Хотел предположить правильно ли выбран тип блока в программе в списке справа…
Надпись но пин точно про контакты у меня было на ews 4.3. так

Какой версии вас ews блок?

AlekseyAAV

Какой версии вас ews блок?

А что?

У меня с такой надписью на ак90 с али — евс лег) Проверь свой работает ли еще.

Ок а если лег что делать потом

Новый (аналогичный рабочий бу евс) и програматор, в него ложатся ключи, вин, исн, пробег.
Знаю что мне просто не повезло с косячным ак90 с али, но все-же…

прижал сильно, держишь, пробуешь считать, не получается, поворачиваешь разъем на 45 градусов и все поновой, пока не считает.

У меня не сгорело, хотя тоже опасался))
Тоже помучался немного. Как считалось, сразу файл сохранил, чтобы если что в новый блок залить.

Ну ты даёшь))). Ладно буду пробовать)

Если не читает евс попробуй разъем чучуть подточить у меня тоже были проблемы подточить только после этого все получилось контакты не достают и в разъеме есть упоры их тоже убирал

Я где-то час мучался убирал пластик с контактов там где точил говорят еще лак с платы надо счищать но я не чистил

1. Положение разъема правильное опытным путем нужно определить.
2. Прижимать разъём сильно и держать при считывании и записи

Never add power using xprog K-line, only with AK90 and chip adapter and only when you can not read without power.

Hi,

my AK90 arrived today and I was able to program some transponder (7935) based on a file I read with my xprog.
The problem is, I cant read any EWS (Pin no Touch error) with the ak90 and the clip. The contacts are perfect clean and I even tried to put external 12v to the EWS.
I tried it on different modules and even rotate the clip.
With my xprog reading works perfect!

Would somebody be so kind to share the pinout of the adapter, so I can check it? Either the adapter is broken, or the ak90 itself.

The problem is in the socket see attached photos, ofcourse that to reach this conclusion disassemble everything. I hope you learn.

You need insert the socket until the end. no space between the socket and the circuit as this picture

Who has pin out the 9 wire to the socket? After that who has pin processor legs to pcb solder point (from the back). Post it for us so we can check if the cable is the issue or is it the hardware.

What is the green wire connected to? I can trace all but the green wire, measured with the multi-meter and no pin is connected to the green wire which is pin 5 on a previews posted diagram. Should that have 12V and if it does, how come isn’t connected to any pin? Would my adapter be faulty? Any of you can see where the green wire is connected? Maybe upload a picture please!

Thanks!

Hello all,

I couldn’t read with the AK90+ so I ordered another one. I did try 4 laptops and two computers, two EWS modules with Win XP 32 bits and Win 7 32 bits. I cleaned it properly and try everything, even trace all the wires. I noticed the green wire (number 5 i think) has no connection to any of the little pins on the chip reader.
Did any of you trace the wires? Is it need for all 10 to be connected to a pin?

I found a strange problem with the EWS 3 on my diesel 320d from 2000
After it was playing trick on me with the starting and getting error EWS module and errors with keys not sending the code, I replaced EWS antenna with a new OEM one, Replace contact on ignition, no joy. Re-synchronized few times with INPA but the problem will come back.
One day I took out the EWS3 module to see does it overheat, it didn’t so I put it back without bolting it back in place, just connected and left it hanging there. I am driving the car for a week now with it like that without any problems, starts any time, even with he key that was not working anymore.
I must get some contact cleaner and clean the contacts , also have a proper look at the wires.

I would still like to try program another key as I have it cut now, spend 40 euro on it and the cut but I am awaiting on another AK90+ for a week or so.

Any tips?

Did it helped to replace the whole unit? Have same problem. As far I can tell pin 5 is not connected.

In need of help like everyone else here. To Mnbcv, there is one pin that not connected. Did a pinout after having «no touch» issues, bought a second AK90+, turned out issue was inside the box.

My Question is: I wrote to an aftermarket key for slot 10. Everything went smoothly, but the key won’t start the car. When I scan the key, it has the cars info. I’ve tried two aftermarket PCF7935AA keys on different slot, but no luck. I have a factory key that works, but I’m trying to create spare keys. It’s for a 2000 BMW M Roadster, utilizes EWS 3.D. On some instructions, it say it will write the key, and afterwards write back to the EWS. In my case it did not write back to the EWS. I’ve heard both ways, which way is correct? The EWS uses chip OD46J, but on the older style EWS with large pins. I peeled the chip out of the aftermarket key to verify it was correct. Just wondering if I got bad chips. Any help is appreciated. Will upload pics.

i like to lightly sand off the coating just a light scruff, then i hold down the connector on the pin, just leaving the connector without holding it down tight almost never reads, i always hold it down while it reads

I’d try another key and/or chip.

Generally no need to write back new key, but it won’t do any harm.

I take it it doesn’t crank?

Have you checked for EWS errors?

Hi,

Would somebody be so kind to share the pinout of the adapter, so I can check it? Either the adapter is broken, or the ak90 itself.

I used to have this problem too. «pin no contact» and shit. What i did and it works for me every time is clean the legs of the mcu with sandpaper and then put the ews on top of a thick sponge so i wont break it and push the reader down hard.

Thank You PixelsFixed. I haven’t checked for errors yet, I’ll report back. Ordered EWS editor to read bin files and see if I can try a different angle. I’ll upload a pinout of the cable soon for others to troubleshoot.

AK90 Pin No Touch Error

Hey guys. Able to read keys but can’t read the EWS. I have the OD46J chip. I have been at this for several days. I cleaned off all the pins with box cutter, ordered another ribbon cable and even tried reversing the cable on the chip but nothing goes. I even cut the small tabs inside the connector so that the chip fits snug. Used 3.02 and 3.19.

All I get is «pin no touch».

Any ideas? I got three blank keys ready to be programmed and only have one key that I got with the car (valet).

Thanks.
What that means is that one or more pins are not in contact.
