Carprog Tool Frequency Ask Question by Customers

UOBDII collect some questions from our users,it is asked frequency by our caprog users.Hope it helps!
  1. Carprog 4.74 can't open, where to download CarProg?
After all procedures can't open carprog program now.

After all procedures can't open carprog program now.
CarProg v8.21 full fw download!o8BmXCxR!9NmLnlQbU-JrCEC8Tqf4LA

Question: i updated firmware from 4.01 to 4.74 but still have some functions n/a (eg skoda auto detect or obd)
with firmware 4.01 these functions was active. what i did wrong?
Answer: Flashed with 8.21 firmware and much more functions available.
Question: anyone can confirm which is pin 55? Is it left side from top to bottom number 7 is pin 55?

Answer: Exactly you are correct. It is from top to bottom number 7. Now lift it.
If you are using J-link software, let pin55 up until the end of programming, then solder pin55 to ground like in the picture attached.
I did this way and worked perfectly.

Question: I want to replace these tantalum capacitors in A1 adapter, but the replacement must be exact like the originals?
The originals have 106C 49E73 written. Must I find capacitors with the same numbers?

the top numbers are the value, the letter is the tolerance while the second row are just batch numbers so if you are replacing then yes the value numbers in your case must be the same ie 106C, is 10uf
some have a maximum voltage stamped as well but in your case you have to work out the maximum voltage of the board and then add some extra so I would use 25v rated or 35v rated if you are going to use the unit on 24v trucks.

Question: Can someone explain in normal English what carprog is for. Would be nice without (for me) unknown short tags.
So what/which cars can I do with it?
Answer: It is for resetting airbag modules for old models after car crushing.
more details:

Question: Can someone tell me where to buy A1+ adapter for Chinese carprog?
Answer: directly from this one eur13 here

  1. 7.
Question: So found just paid solution get replaced MCU,I'm right?
Answer: no need to replace mcu, it can be erased and reflashed with newest free firmware.
Question: I bought clone carprog v10.05 but most of functions is not available. Is problem with software or firmware? Can I use different version like 7.27 or I need to use software provided seller?
Answer: software is software firmware is firmware
your carprog is most likely got firmware 4 in it
and your wanting what your activation file won't have.
I' ll keep add more here for your reference.
Hope it helps.

Carprog Chinese Clone Rework as Original

Carprog Chinese clone actually can do many things, almost as original, if it is reworked well such as read security codes or read flash

Here a Carprog clone, it cannot read security codes or read flash. It does the procedure but the output is all bad. Either no output or repeated characters.carprog-clone-pcb-01 carprog-clone-pcb-02

many members with Carprog clone can say it will work have to tweak it ,and read the manuals really only for mcu usage. I have retooled and remade many of my own adapters , also changed bridges , caps , oclis crystal etc on mainboard also flashed to 4.74 firm . all the N/a are gone and eprom and mcu reading is great no faults. also fixed ground plane and insulated board from aluminum case with k tape. its working fine now but has a nice coat of dust on it.

To rework Carprog PCB, here is what you can try:
Check A1. You may need to improve the work can.
Carprog 001a-03

First and most important of all is to change 74HC125D to 74HCT125M on your carparog, i have good clone (good pcb) but still did not read some I2C,95 ,MCU. I bought 74HCT125M at farnell change all 4 of them and it is ok now. reading without problems.
carprog-rework-04 carprog-rework-05

Carprog well reworked can read Opel ECUs fine
Actually is not need to use relay as showed in codecard manuals
tested on edc16c9

As we all known, it needs skills to rework carprog, perhaps you could buy a HQ Carprog programmer at the best price (Forget the cheapest!!! you will get what you pay for, especially for China clones)

How to do when you lift pin 55 on Carprog

Now I have succeeded in one Carprog unit(CARPROG FULL V9.31), with help of a sewing needle. It will go wrong because I get up two pin, and then I can not solder back the faulty pin.
Now I have managed to get another one ready for easy flash with J-Link adapter.
But I will make another one to experiment with, and rebuild to full function or better.

Below is some useful tips from forum bros. Wish this helps

*** autocargo says:
… find scrap electronics board and practice on that. I use thin syringe needle and magnifying glass.. No point practicing on your working CarProg….
Use thin solder tip or hot air off course…forgot to say… but I don’t think you would be doing it without applying heat…

*** demelec says:
needle under leg needed lifting and heat with hot air, then very carefully lift only a little just so it separates from pcb solder

Soldering iron you have to use very thin tip and just touch very end of leg to remove ( solder at very end so not actually touching leg) then you can lift with needle
And always use solder flux
Flux is the main key to easy working
