I'm not aware of DIS having any coding capabilities. NCS should be capable of coding every module on the car. Do you have all codes cleared from the ecu? It can't code the module if there's an ecu code.

AM.

Older DIS versions have the same capabilities which were later separated into Progman, which was used for programming and and coding, making DIS purely for diagnostic measures. Though Progman is so slow that it takes ages to make even the simplest coding tasks.

I managed to install and run DIS.
However it seems there's some connection problem.

The reason I need it, is because I want to code IHKA module. That's for my E39 1998. I sourced 2 panels from 2000 and 2001 and neither of them work. I was told that coding with DIS specifically will make them work.
I tried coding with NCS Expeert without success.

Maybe my DIS version is too new, V57? I'll try to find V44

Aren't all E39 post 3/97 IHKA versions coding index 03? How has the old one failed and how are those replacement units behaving. Can you connect them with diagnostics? So the coding with NCS does not go thru or it does but the problem still persists?

Do a search on DIS connection problems at https://www.bimmerfest.com/forums/bm...ogramming.175/. If INPA is working fine, then your issue is DIS config settings and you're good to go. Take time to search. By the way, have you tried coding using NCE-Expert Dummy? It masks the complexity of NCSExpert and makes coding easy. If you can't code with NCSExpert, then I don't think any other software will as it's the most down-level and you can brick modules easily.

NCS Dummy makes working with NCS Expert a lot easier:

A basic coding like this works with SG_CODIEREN. It will code the module properly according to ZCS (if that's not corrupt). Just make sure the FSW_PSW.MAN file is empty if you are not sure how your NCS profile is set. I don't see how NCS Dummy would help in basic coding.

Interesting. I didn't know that. I DID use Progman once years ago, but have since used NCS Expert with Dummy for my limited coding needs.

I will quote someone from another forum:

That's because later cars don't have a relay on the blower supply wire so newer IHKA won't send a signal to activate that relay in older cars. Also the AC compressor won't work since newer cars use 1 wire to communicate with engine ECU and older cars use 3 wires. To make blower work, you can remove pin 14 from the blue connector in IHKA and connect it to the wire that goes to pin 1. Pin 14 is responsible for activating this relay. After that, the blower should work, but most likely the air conditioning compressor will still not work.
However, there is a better solution. All you have to do to make everything work is to recode IHKA with DIS (it must be DIS, not NCS Expert etc.). I'm not sure if it will work with all IHKAs and cars but I have successfully fitted '99 IHKA to '96 car using this method.

The way my module failed is that I broke it. The buttons started falling out and were cracking. I tried gluing them, then I couldn't press them anymore. I took the IHKA module apart, and instantly regretted it. It was a huge mess. Took me a few hours to learn how to put it back together. Then I was playing around with it in the car while it was apart and was connecting it and touched something on the board that wasn't supposed to be touch, and I smelled something burned on the module lol....

So I got a couple of used modules, but they don't work. Basically the fan speed is not working. No matter how fast I set the fan, it doesn't blow any air.
I tried coding with NCS Expert and it coded fine, but it didn't fix the issue.

That separate relay on blower final stage voltage supply was on pre 9/98 models. After that the final stage gets continuous (Terminal 30) voltage. So that relay can easily be bypassed.

Yeah, I remember my first DIS install had the Progman/Coding button active and I could code modules with it.
