i getting all the time pin not touch error
i clean the pins many times
i got dot on the mcu and i got red dot on the adaptor cover
what i doing wrong?
thanks

[totalkey]

it is driving me crazy - please advice

[gwee]

try changing the dot position, sometimes chinese made mistakes :D

what is the cross inside the adaptor?

[cjawahir]

look at the pic you may need to cut foil on the pcb .

what picture?

[cjawahir]

hello this pic should come up when u choose the mask .

cj

ps you can check the dot on the connector thats pin 1 should be ground , pin 2 should be 5 volts .

[totalkey]

i got different pcb - anyhow the error is pin no touch

[totalkey]

does it working on windows 8?

[totalkey]

anyone got the pinout for ak90 and the mcu?

[Siham]

I don't think it will work well on windows 8 .
AK 90 doft and driver are litle older for win 8.

[bali motor]

nooo.... im many times do it... never loss data... if can not read ews... im just install power... all can read..
if your still can not read.. you try another ews.... maybe your cable is problme..
or one solution.. put out mcu and read by ETL

[totalkey]

nooo.... im many times do it... never loss data... if can not read ews... im just install power... all can read..

Does the "pin no touch" errors happen also not just for contact problems?
And can you show how to power up the unit?
Thanks

you have manual or auto tranmision?

[Q UOTE=bali motor;2415385]you have manual or auto tranmision?[/QUOTE]
I am not sure, why?

[bali motor]

wait.. im will looking my diagram... because manual have 1 positif and 1 ground... auto tranmision have 2 positif and 1 ground.

[bali motor]

for manual tranmision
PIN 5 = 12 volt
PIN 7 = GROUND

for auto tranmision
PIN 5 = 12 VOLT
PIN 7 = GROUND
PIN 9 = 12 VOLT

for manual tranmision
PIN 5 = 12 volt

ps - with xprog m

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

[obdsystems]

I'd remove this one from PCB to adaptor. the ak90 software warns me every time - do not read this chip 47j.

Rather be safe than sorry

If u have ak90.. I use ak90 for all ews.. Never loss data.. Just clean leg mcu.. If can not read just add external power.. All done.

u cannot read via k line . only ews3 with od46j can do that .

I'm lost here? :(

How should we read the chip? WIth XProg?

warning always displayed on my AK90 to never do this chip. Whether that means by CPU plug or someother K-line method

Yet to see this 47j but one day...

[bali motor]

If u can not read it.. Just one solution.. Remuve mcu and read by etl..

[obdsystems]

Or XProg via adaptor?

[bali motor]

If u use xprog.. And scurity not unlock.. Data will loss.. Use etl will safe..

[bali motor]

Check connection adapter ak90 maybe have one pin loss.. http://tapatalk.imageshack.com/v2/14/11/18/66ffff94bc724415b35cadf962d94ce6.jpghttp://tapatalk.imageshack.com/v2/14/11/18/d517fbc52402f51fbf27e1079d24a05f.jpg
use sandpaper to make the surface flat adapter. see picture ..

[kemaster]

For 2D47J I use BMW Key Programmer from QCET. It reads secured but needs to remove from PCB and use PLCC52 adapter. Fail just once to read but didn't erase the data inside (lucky me). :)

[ninja123]

so can ak90 read ews2 2d47j in circuit or need toi remove mcu?

ninja

[bali motor]

Im never loss data read ews2 2dj4y by ak90.. Why you have many problem.... Clear leg mcu and use contact cleaner if needed.. And plug adapter ak90.. Read and done..

[ninja123]

what solvent do you use to remove this hard red varnish?

I find this very hard to remove :(

ninja

[bali motor]

use a cutter . and wear clean disposable brush .. Spray contact cleaner if necessary.

Clear message on my AK90 - do not read "47j". every time!!

doesn't fill me with confidence. rather walk away from job

Yeah will try paint stripper next time cheers lads

[totalkey]

funny thing - after i read it and make transponder car start normally but the next day car stop start, read ews again and and write back to mcu and got all fff now
plug out the 12v and now reading and writing is ok and car start ok - no need 12 v for reading

[Horst12345]

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.

[ray-ray]

Open & rework the soldier joints.

[Horst12345]

I opened the plug and checked all connections. All seems to be fine :thumpdown:

Here is the pinout. Can somebody check this please on his working AK90?


Thanks!

[lastbornzombie]

What mask are you reading and which ews, I do alot of these but stand clear of ews 3 mask 2d47j with AK90, sometimes I clean them up 3 times try and clean closer to the chip where the legs meet.

[Horst12345]

I tried different modules (EWS2, EWS3) with different masks (0d46j). I cleand pins ten times, they look perfect. Still "Pin no touch"...

To check that the cable is ok, can someone with a working ak90 please check the pinout, if it is identical to the one I posted.

[totalkey]

Did you give 12v in 2 pins ?

[Horst12345]

@totalkey

Yes,
pin 9 - ground
pin 10+11 - 12V

[totalkey]

@totalkey

Yes,
pin 9 - ground
pin 10+11 - 12V
So try only 1 pin for 12v

I also tried that. You had similar problems, could you please check my pinout with yours?!

[obeids]

for manual tranmision
PIN 5 = 12 volt
PIN 7 = GROUND

for auto tranmision
PIN 5 = 12 VOLT
PIN 7 = GROUND
PIN 9 = 12 VOLT


Hi

Is this pinout for the EWS connector pin numbers or the Chip Pin numbers?
I got EWS2 fro E36. Client tried to read using AK90 but all blank. Now I have another EWS2 from junkyard, when read then reads data on ak90 but when press write key then say " DATA ERROR". ANy suggestions? Should we apply power as mentioned in posts? Also should it be 12V or 5V?

Thanks

[estate]

There's a lot of effort being put in to trying to fix a ?25 tool........ Accept yours in broken and just a buy a new one and move on, don't waste time on it. I bought an AK90 and within 10 minutes of taking out of the packaging had a fully working ews3 e46 key. Well worth getting a new one instead of wasting your energy on this one :)

Volt for ews not have 5 volt..
Just question. In your car have out put 5 volt? Why you ask volt for input to ews 5 volt. ?? What you think?

[Horst12345]

I ordered a new AK90 and it works like a charm. The old unit is broken...

[estate]

Excellent when working right! Get KD200 for easy remotes now :)

hi
where i can buy a good quality mcu adapter to use it with AK90 .old one can not read ews mcus.

There are 2 ak90 on the market $50.00 clone not working. Then there a $90.00 unit all is working, so buy the better one.

[jakesman]

got mine and from the start could not read any ews with adaptor , cable was wrong way round first was last and last was first on the plug side , turned around and happy till today

[vh116]

I have the same problem. "Pin no touch"
Can anybody make picture with correct pinout 10pin cable? Thank you.

pics/description is on this thread - just go back a couple.

as said, if u have trouble, it may be better just to buy another ak90

I have also bought a ak90 but shows "no pin touch" i have tried all positions still shows it.

Any idia?

The problem is in the socket see attached photos, ofcourse that to reach this conclusion disassemble everything. I hope you learn.
In the socket cut the 4 plastic as the picture. 345448

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

345449

I attached photos to get the pinout

[devonhiee]

I am also having problems with "Pin No Touch". I am on the second test cable already. Hopefully some of the pictures here will help., Already cut the little plastic tabs on the inside of the socket for the both of them.

[Bmkeys]

Iv had my ak90 for over 3 years and have done hundreds of cars with it and never had a single issue.

Just make sure the legs on the chip are nice and clean.

[Bmkeys]

Delete. Double post

[ray-ray]

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.

[obywan]

some help please. Can somewone analyze this dump ?
I read 0d46j with AK90, but cant analyze the dump .
thanks

first 3 keys used , dump looks good

hmmmm,
this is what my editor displays

[spanac]

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!

[spanac]

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?

[mnbcv]

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

[mseriesbmw]

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.

[cniksor]

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?

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.

[mseriesbmw]

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.
