Are these the differences in each of the listed modules after retrofitting the trailer?

Do you see AHM in FA and CAS? Looks like BD gave you a nice list of all the modules that need to be coded. My AHM didn't come with all the lines, so I had to add them and the command myself to make it work.

I forgot to plug the 3-pin BUS connector from the trailer wiring harness .Now i can connect with AHM module . I went true all the trouble to install ISTA P to find out this. But when i try to do the codding with ISTA P it is making me to do all kinds of updates and I was waiting 1+ hours and i just stop it because my battery was dying. I am going to use the NCS expert and do it manually .
I dont have HKL module(because i dont have lift gate option) and in my FRM module I cant find :LWR_STROM_HALT wert_01 LWR_STROM_NORMAL wert_01 LWR_STROM_RAMPE wert_01 To make my lights work do I just need my AHM module programed ? My CCC is red because i did CIC conversion |
Skip the HKL step, I included it in error

Do I have to purchase the OEM wiring harness and install this if I want to read the AHM module? I haven't done that yet.. is that why I'm getting the message? |
The OE harness comes with the module. You can't code it if it isn't physically connected to your car :)

Understood. Appreciate the response blue dragon! Thanks for your work and others in figuring out which settings need to be coded in order to add a hitch. I saw this thread and others in trying to figure out exactly which settings need to be coded.
I ordered the harness yesterday. Hopefully in 1-2 weeks time, I’ll have the harness and hitch installed :). Love your X5 btw — looks awesome! |
I think I am missing something. 08 E70. All wired up. I did manage to add +AHMU to the CAS and FRM with NCS Expert, and the AHM module shows up now. But its missing code(only has 2 options). And FRM is missing the LRM_STROM_*** codes.
Blue Dragon, it appears you posted CIC codes, do you have CCC? I dont have a RPDC module, but I do have PDC (which I am assuming controls front and rear). And while I have managed to use NCS Expert to alter code on both this E70, and a E46 before, I have never added code. It is as simple as pasting in code in the right format? Thanks guys for any help. I guess this is me not understanding NCS Expert enough. |
