BC Racing Coilovers Review - Another EHCII System Removed

BMW Scanner 1.4.0 finds a module called "Electronic Height Control" but there are no coding options. Can only read and write the raw hex. There were a couple other related errors like in the anti-lock brakes about the failure of the height system.

Running the scanner finds the modules that are installed and doesn't find the ones not installed. Which makes me believe it's possible for this one NOT to be installed. So are we talking a software module or an actual thing that can be pulled out somewhere?

I still have my module connected. I don't see an error anymore on the dash after installing the resler ibus interface. Unless I scan through the obc functions using the stalk. Then it will pop up. But if I scan the truck the ehc still reports all kinds of errors due to the missing equipment. Ultimately I want to get a laptop to edit the VO and then I can physically remove the ehcii module and not have ghost errors.

Thanks @Purplecty. On the LCM page these would appear to be options remaining to uncheck...

- SELFLEVEL SUSP INACT
- SPEED LIMIT (for the do not exceed 35 MPH warning?)
- CHECK AIR SYSTEM
- AHC INACTIVE
(among many others not obviously related).

Nevertheless I still saw these alternating on the screen...

- SELFLEVEL SUSP.INACT
- MAX. 35 MPH
- LIMIT --- MPH

Unchecking all kinds of things out of frustration would likely not help the next person until unchecking:
- TTX_S1_(CODE)
- TTX_S1_1
- TTX_S1_2
- TTX_S1_3

No clue what those mean. Not saying I even have the software but, success. I do not see any of the three errors. However, I do still have the yellow tire pressure light. I assumed it was related to the EHC system since I'd tried resetting it numerous times holding the button. Unrelated?

I have a pre-facelift so the EHC II maybe be slightly different on what parameters need to be programmed out. Removing the EHC II from the ZCS and then reprogramming the LCM and whatever other modules have settings for EHC II to the new ZCS may be the best route to take.

This is what I believe for the dual axle EHCII. It might be tied into the DSC programming as well because I have pulled some stability control errors out of the truck with the Foxwell. Doesn't illuminate anything on the dash, but have gotten some errors.

I hope to get a laptop for BMW software package, buy a proper battery voltage supply for coding, and then dive into it sometime in the future. Will certainly update when I do. But if my audio build is anything to go by... I wouldn't hold my breath.

What errors show up in the DXC system? These are the 2 parameters found in the LCM using NCS Dummy that you would probably need to disable using NCS Expert. The idea is to have all the modules that think you have EHC to no longer think about or look for that option...

Also the coding on DSC module is different with 2 axle self levelling.

Why don't you do it properly with NCS. Just remove the option bit in ZCS SA part and code all modules.

You can do that as well! I just like to understand what parameters are different in each module affected which can also be determined after changing the ZCS.

Thanks again Clavurion. I saved that coding post when you mentioned it before. I will definitely do that when I get a laptop up and running with the correct software, cable, and a voltage source for the truck.

When you code out the ZCS SA will it auto code the other modules when you run the job? I have never used the software just been trying to familiarize myself with it and the process as much as possible to avoid potential screw ups on my part.

[Purplecty]

You have to code each specific module affected by the new ZCS to know the new ZCS.

Change the ZCS by subtracting that bit mentioned earlier. Delete the last check bits on GM, SA and VN parts and check the tab that NCS will calculate new check sums. Save (ZCS_SCHREIBEN) the new ZCS to EWS and instrument cluster (modules which contain ZCS). Then code all modules (CODE CAR). The parameter value changes are made on every module according to this new ZCS.
