Ncs expert неверно выбрана серия ошибка

Have spent my entire Saturday on this:

All running on XP and also tried on Win7 x64

INPA is working fine. Battery and ignition both ON

When running NCS Expert, try to read the VIN from ECU i get VIN Faulty
Vin is faulty
COAPI-2000 Error or in ECU description file (SGBD) IFH-0018 CAS
COAPI-2000 Error or in ECU description file (SGBD) FGNR_LESEN
COAPI-2000 Error or in ECU description file (SGBD) FGNR_A_E65CAS

Solution 1:

If you have Standard tools 2.12 you are fine.

Check if you have E89 folder in C:NCSEXPERTDATEN

And make sure that you copied all files from sp-datendaten*.* to here C:NCSEXPERTDATEN and here C:NCSEXPERTDATENE89

Just recopy this and check if this helps

Solution 2:

You can only run INPA or NCS one at a time, not simultaneously.

Also, sometimes mine gives me that error. It’s usually because I didn’t initialize the USB cable properly. Unplugging it, closing NCS, plugging it back and restarting NCS usually solves my problem.

Hope this helps.

Solution 3:

you are missing some files for E65 at sp-daten. Try to download newer spdaten and copy at least e65 folder or update whole data.

Solution 4:

make sure you update your daten files correctly as well

you can do the following copy-paste procedure: (copy the files and replace )

Target —————————Source .(SP-Daten-Exx directory )

NCSEXPERSGDAT ——– .ipo files
NCSEXPERDATEN ——– coding data (daten) for models
EDIABASEcu ————– .prg files……

If not work, please empty your .man file .. delelete everything inside then save.. then try again

ON YOUR NCS EXPERT FOLDER YOU SHOULD SEE A FILE:

FSW_PSW (MAN)
FSW_PSW (TRC)

INSIDE THE (MAN) ONE DELETE ALL THE VALUES INSIDE THEN SAVE AS.MAN SO FSW_PSW.MAN MAKE SURE SAVE AS ALL FILES OTHERWISE IT WOULD SAVE ONLY AS PLAIN TEXT.

After You Do That.. Try To Read The Car Again.. So Ncs Expert,f1,f3 E89,cas, Then Back

NOTE:

DUMMIES GUIDE TO UNDERSTANDING NCS AND CODING

This is roughly how it works… and my dummy interpretation of it. Please read it fully if you want to understand, this isn’t exactly a quick cheat sheet guide.

On Pre ’02 cars the coding is slightly different method than Post ’02 cars. I am only going to elaborate on coding individual parameters, you can go learn how to code entire modules thru the VO later once you learn the basics below.

The first part to understand is what this stuff about ZCS/VO or “vehicle order” is. When BMW makes a car, they create whats called a “vehicle order”, this is basically a bunch of numbers written into the car that tell what modules are installed in the car, regional info etc. This is like your car’s DNA! for example if the car has a sunroof, or a convertible or radio etc etc and that it was meant for US,Canada,France etc. Because each car is different with a different set of options/modules or country that its located, the “vehicle order” aka. “ZCS” or “VO” may be different. Why is it called ZCS you ask? because its abbreviated german, and its confusing as hell.

The VO is written into a couple modules of the car, usually ones that start with an “A”, like AKMB or ALSZ. On some cars its written elsewhere. In my 02 M3, the VO was written in ALSZ and AKMB. On my ’00 328ci it was stored in EWS, KMB. Its nothing more than a string of text/numbers stored in the flash memory of these modules, nothing special. Why is it written into two places? because if one module is failed and has to be replaced, then the other will serve as a backup so you can code the new replacement module to your car. For example ALSZ is the “light switch module” in your car, for some reason it fails. When you buy a new LSZ/LCM, you can retrieve all your settings of VO from AKMB and then code your new LCM to YOUR factory settings. The chances of both modules failing is slim, but if it does… you’ll have to contact BMW so they can give you the VO for your car from their records.

OK the one difference is pre-02 cars don’t have a VO. Those cars have their ZCS (which acts like a VO) stored in the EWS or KMB modules. The stuff below is basically identical however for individual parameter coding.

Now go get into the basics of coding.

1. When you load NCS expert bmw coding software, you need to load a profile. These profiles just change how ncs expert behaves when you read your car. The two profiles i stick to are “expertmode” and “revtor’s expert profile”. if you don’t have it, you can find it on the net easily. In order to code your car the first time, you should pick “revtors“. This has something called “manipulation” enabled… ill elaborate on that later.

2. Once the profile is loaded, you basically need to select Vin/ZCS/FA in order for ncs to download VIN info off your car. Once it does this, it will ask you to select a module. Why? because it needs to know your “vehicle order” information. In most cases it will probably be in an “A” module. if it doesn’t load, or cant be accessed, no harm done, just try a different module. When it is able to read it, you will see a long string next to “FA” starting with your chassis “E46_” followed by numbers and text along with #’s and $’s. This is your VO. Now that NCS Expert knows it, it can code your car properly!

CODING HAS NOTHING TO DO WITH THE MODULE YOU JUST SELECTED TO READ THE VO FROM! This perplexed me for the longest time, I didn’t understand why i selected two modules each time, or what the difference selecting AKMB or ALSZ or etc the first time was. Well… It has no bearing!! all NCS is doing is reading the text/number string that is your VO off the memory in these modules in this first step. You will actually select the desired module to code in later steps.

** PRE-02 cars, you wont see the long FA “VO” string, instead there will be a few lines FG, GM, VN, SA followed by numbers, its basically the same thing different format. For all intents and purposes this is referred to by me as the vehicle order or ZCS for a pre-02 car.

ON POST-02 cars select any module with “A’ in front of it, on PRE-02 the “A” modules wont work, you will need to use EWS or KMB for this step… It doesn’t matter which. 

Now this guide will touch on the basics to code INDIVIDUAL items on your car. The steps to add items to your VO and code your modules is different and i wont comment on that here, because it will confuse the amateur. Just understand the basics of individual coding first, then coding from your VO will all make sense later.

3. The next part is to download your factory settings in your car to your PC. Once you get the VO loaded, you hit the BACK button. The default job in NCS is to write SO BE VERY CAREFUL here. You will see all your modules listed, for example “EWS,ABG,ASC,KMB,APL,…..etc” and underneath “SG_CODIEREN”

NCS at this point is set to SG_CODIEREN, which means to WRITE to ALL modules listed. You don’t want to do that.

4. So now select “Process ECU”, and select the INDIVIDUAL MODULE you want to code. For example LSZ (light switch module). Once you do this, it will say only LSZ (and not all the modules in your car).

5. Now you want to change the job from WRITE to READ. Select “CHANGE JOB”, then select “CODIERDATEN_LESEN”. This is to READ DATA.

6. Once selected it will confirm this by indicating the module and job type on the screen. Now you are ready. Hit “EXECUTE JOB”.

It will say Coding Activ, then Coding Ended.

7. At this point, in your NCSexpert/WORK/ folder there will be a file called “FSW_PSW.TRC”

This is what we want, the coding of your LSZ module that we read earlier. IMMEDIATELY save a backup of this file, rename it to FSW_PSW_LSZ_ORIGINAL.TRC and save it somewhere in case you decide you want to revert to the original copy. Now I want you to resave another copy of this FSW_PSW.TRC file as FSW_PSW.MAN (manipulation…hint hint). Make sure it doesn’t save as FSW_PSW.MAN.TXT or some crap like that, it wont work properly.

OK why all this juggling?? because NCS expert only reads modules and saves EVERYTHING as a FSW_PSW.TRC file. Regardless of what module you read in your car, this is what the filename will be. And everytime you load NCS expert, this file is constantly erased, written and re-written. So thats why we are saving it as FSW_PSW.MAN so we can alter it safely without our copy being overwritten.

8. Now open up FSW_PSW.MAN with a text editor.

You will see a long list of stuff like this..

This is where you can code. now its all in german, so you will need to run these words in a translator (google) to understand it, OR you can use NCS Dummy that translates this stuff for you and gives you all available parameters, but thats a whole different program and you ought to learn how to use it.

This is what the above looks like if translated. Now you can see how we can deactivate/activate certain things. I’m going to deactivate DRLs here.

By changing to nicht_activ, it deactivates this setting. Now don’t go crazy, some codes are redundant so changing just one thing wont do the trick. This takes some time and effort to find the right code/codes to work with.

9. Once you are happy, SAVE your FSW_PSW.MAN file.

10. Open up NCS expert, load up “revtors” profile (with manipulation enabled), and reload it to the part where the VO is loaded and its asking you to process ecu (Basically steps 1-3) Look above how to do this. Once you’re there, select “PROCESS ECU”, select the correct module you are coding, in this case “LSZ”. Then select “CHANGE JOB” and make sure you pick “SG_CODIEREN”. Once this is done, you are ready to code the car.

NCS will basically now take the FSW_PSW.MAN file, and overwrite the codes in your car’s LSZ module with your new settings. It only uses the MAN file because you are using a profile with “manipulation” enabled. The other mode “expertmode” does not have manipulation, and you cannot code individual stuff like this using that profile.

11. Hit “EXECUTE JOB”. Wait till it says “Coding ended”. Now your new LSZ is coded. Turn off the car, and restart, and check to see if your results are as expected!

12. Open up the /WORK/ folder, open the FSW_PSW.MAN file, select all, delete, save and exit.

Viola! Thats it. You are now an expert on coding individual features!

Now what do you do if you screwed it up or something is behaving funny and you want to go back to original settings. Or you cant remember all the stuff you changed, or don’t like the results.

To load up the ORIGINAL factory defaults if you mess up.

Go to your /WORK/ folder. Open FSW_PSW.MAN, select all, delete, save & exit.

Load NCS Expert

Select “Expertmode” profile

Hit “VIN/ZCS/FA” to load your Chassis and Vehicle order info

Hit BACK

Hit PROCESS ECU

Select the chassis, then module you F’d up on. For example “LSZ”

On Pre-02 cars It will say “LSZ” and underneath “SG_Codieren” along with some files LSZ.Cxx, LSZ.PRG, etc etc. SG_CODIEREN is the correct job you want.

On Post-02 cars It will say “LSZ” and underneath “SG_Codieren” along with some files LSZ.Cxx, LSZ.PRG, etc etc. Hit CHANGE JOB, Select “FA_WRITE” Job.

“xx” is usually the specific Coding index used in your default module, its a number. think of this like “firmware version”.

These files are basically from your /DATEN/ folder and contain the proper coding information specific to your car. How does NCS know which files to use? Because it knows by looking at your VIN and VO, then selects the correct files. NCS will then basically read these files, then read your VO and re-write the proper codes, features, activate, deactivate everything to your factory settings.

The job is SG_Codieren or FA_Write because you will WRITE your original settings back in.

Hit EXECUTE JOB.

Viola, your original data is re-written and your car will work again. Hopefully.

This blog collects some errors of NCSExpert and what they mean and how to fix it. Hope to help customers.

Notice: These solutions are collected from user members, you should try these solutions at your own risk!

ERROR1:

COAPI-1020: cannot read file C:NCSEXPERTWORKFSW_PSW.MAN

SOLUTION:

Rename your modified FSW_PSW.TRC to FSW_PSW.MAN. Refer to the DIY guide and make sure you follow the steps.

Error2:

Trying to code Mini R56, When select R56 and then press F6 to go back, get the following error:

COAPI-1142: PSW faulty 25_s

Solution:

When you are working on different model cars, be sure to clear out the content in the FSW_PSW.man file. Do not delete it (the file), just save it as a blank document. This is actually a good thing (recommended) to do after coding a car.

The error popped up because of different values between the 328 and the Mini.

Once you have a blank FSW_PSW.man file, you will not have that error.

Error3:

COAPI-1141: FSW faulty c:FSW_PSW.TRC – erase contents of your .man file

Solution:

Confirm the 2 files C:NCSEXPERWORKFSW_PSW.MAN and C:NCSEXPERWORKFSW_PSW.TRC are empty and there both 0KB.

Error4:

when trying to code X5 2011.

Got this: FA: # -kle1

Solution:

Update your NCS with ista/p v41. Need the v41 daten in order to do anything with the car. Usually when you get those errors, it’s because the vehicle has an option code (or build criterion code) in the FA that the loaded daten doesn’t understand/recognize and you need to grab the latest daten so NCS Expert knows how to handle the options.

Error5:

COAPI-1043

Solution:

1) You might have a bad daten file. In order to determine whether you do or you don’t….download the TRC file. Rename it to MAN without altering anything in it. Then attempt to code with that UNCHANGED man file. If you still receive the COAPI-1043 error then it’s a bad daten file. Find an older or newer CAS2.C05 and replace the CAS2.05 file in your current daten folder.

2) If it’s not a bad daten (i.e. it didnt get kicked back) then it is bad coding. Whatever changes you are trying to make in you MAN file prior to upload are not understood by the car. The code is nonexistent and better research needs to be done in order to code the right module. All cars are not created equal so make sure you understand where you got the code from and who had success using it.
