Have you done the retrofit yourself or through a dealer/specialist?
Hi karma_police,

I also read about the possibility of the ICM permanently registering an airbag deployment event but I do not know if this information is factual or speculation. I do not know the answer to this question.

In general, it is hit-n-miss when purchasing used parts for a retrofit but that is part of the fun/challenge.

Yes, I retrofitted ACC myself, as well as most of the items in my signature.

I was lucky enough to find a near-complete kit (ACC radar, ICM-High, ABS pump/DSC and ACC+front PDC wiring harness all from the same donor vehicle) on ebay that ended up being fully functional.

The most challenging aspect of this retrofit for me was identifying the correct part numbers for and locating a used ABS pump/DSC assembly.

All the Best,

Larry
