Seat Swap Coding Help
Hi all, I need some advice with coding. I've coded a few times with success, but I'm definitely an amateur and it's still intimidating to me.
I recently did a seat swap from heated manual to heated electric w/memory. The wiring and install went very well and everything worked except for the memory function and drivers side heat which I hoped coding would fix. As per the guide I was using I added 459 and coded FEM and HU. The memory and drivers side heat still doesn't work and now my AC panel shuts on and off and my idrive is glitchy. I have know idea what went wrong. Question #1 is how to fix the errors? Should I re code from scratch? (Connect => Read FA (VO) => Activate FA (VO) => Read SVT (VCM) => R-Click ECU (itself NOT CAFD below) => Select CODE) Question #2 Anyone know the proper procedure to get the memory working? There seems to be a ton of VO for different seat configurations. I have the same seats as the guide I was using and it says "add 459 to VO and VO code FEM and HU. In some cases, CAFD injection to SM/SM2 may be also required" Which ECU would that be under? Thanks to anyone that can offer some assistance. |

Hoping someone can help...
The guide I used for coding seat memory said: "In some cases, CAFD injection to SM/SM2 may be also required" I'm not showing an sm or sm2 module. Even after VO coding seat memory. Is there a trick to get those modules to appear? |

So, you definitely have to see the SM/SM2 module on the list, and of course a green dot next to it, and if not, you have to inject the latest CAFD or the CAFD that is best matching to your current i-step...
One of the reason that it doesn`t work, is the type and year of the Seat Module (SM/SM2)...there are two types, till 07/2013 and after 07/2013...so, check please the date on your big white module under the drivers seat. If it`s not matching your car`s product year, you have to change the module. The older module is CAN, and the newer is CAN2... If everything above is ok, check please your wiring, fuses, grounding cables, because it`s not plug and play, some things have to be changed...like for example, after swaping the el. seats, the drivers seat is not controlled via LIN any more, it`s controlled via K-CAN, new 12v wire should be connected from the fuse box under the hood...and so on...which i hope that you already have done... And yes, if you get it done working, and the SM module apears on your list with a green dot CAFD, you have to VO code FEM, HU, REM and ACSM |

Thanks for the response, but I got everything working last week. New seats are 2017 so KCAN2. I spliced in behind the head unit and everything's mint.
