I pulled the attached .abt's a little bit earlier today as backups and have not made any changes since. Please let me know if you need any others.

I have a "1" in that position.
Yes, I have 4 front sensors. Received an error today but replacement OEM sensors were delivered Friday. I will change sensors as needed then update in a following post.
All changes are as listed. Obviously, there is a data issue either due to a bad sensor, wiring (used OEM harness) or possibly this? Maybe due to chip shortage my IPMA cannot handle 8 channels?@BobWadd Bob, I'm clocking off for the night so I'll assume your front and rear sensors are functional but just not configured correctly.
If any of the following changes list a different "from" value, don't proceed and let me know. The following assumes that you have 4 front sensors in the front bumper and 4 rear ones in the rear bumper. That should be the case if you have copilot assist 2.0 as your window sticker says. It's quite possible that these modules don't know what to do when you have 8 properly wired sensors, but are only configured for 4 ?
In your IPC, it looks like your front park aid system isn't right. If you don't get any front park aid beeping or graphics when you're a foot away from an obstacle at the front of the truck on the sync screen, then:
Change IPC:
from 9 to D, and:
720-09-02 xxx* xx--
from 8 to 9.
720-10-02 xxxx *x--
Reboot the IPC in FORScan service procedures (the spanner icon) and test for front and rear parking sensors operation. Probably won't work.
If no effect, leave these changes in there for now.
In your IPMA, front parking assist is disabled.
Change IPMA:
From 7 to B, and:
706-02-01 xxx* xxxx xx--
From 0 to 4, and:
706-02-01 xxxx xxxx *x--
from 0 to 1.
706-12-01 *xxx xxxx xx--
Reboot the IPMA. Test front and rear operation, front probably won't display yet but will be configured to.
Same issue for your APIM.
Change APIM:
from 1 to 2, and:
7D0-08-01 xxxx xxx* xx--
from 3 to 7, and:
7D0-09-03 xxxx xxxx x*--
from 8 to 0 (we can change this back if needed, but it should be fine).
7D0-09-04 xxxx xxx* xx--
Reboot the APIM. Test front and rear operation; all should be good. If not, reboot modules in this order: APIM then IPMA then IPC. If it's still a problem, report back any issues explicitly.
You should also check for any DTCs, especially if the IPC displays park aid fault messages. You may also need to run the parking sensor calibration service procedure in order to correct sensor focal length and populate sensor homography data.
9 is fine for that byte. The 8 just means that the highest value bit of the byte needs to be enabled. So that means to add 8 to whatever else your get in that byte. The lower 3 bits of that byte are the upper 3 bits of the 7 bits used for the cancel blink num.I’ve run into an issue with the turn signal number of flashes. I added the heated steering wheel and enabled it in the SCCM. The problem is the enable digit is also the first digit for the number of turn signal flashes. The highest I can set the two digits to is 8C. Which only gives me three flashes. If I add 4 to 8C it bumps the first digit up to a nine and the HSW requires an eight for enable. My understanding of hex is minimal at best so maybe I’m missing something. Any help would be great.
That's good.I have a "1" in that position.

As I mentioned before, having 8 channels physically connected but only 4 channels configured could pose issues. I don't know. I spent hours on this yesterday under the assumption that all hardware was functioning. You can revert all changes I've posted if you like, but I've got nothing more for you until you have 8 physically correct channels, or until you restore the truck back to its original, physically (including wiring) correct 4 channels.
I've been comparing some of your settings to my saved off values before I also added the front sensors and ACC a few months ago. Some things to note:
As my stock KR has working rear sensors, and this is disabled (0) on mine, I didn't mention changing it in my post.
Agreed, didn't think of those Two. They remove control of park aid where it's not supposed to be on our trucks. To explain "swapped", some modules have complementary (inverse) logic to implement functions; as you know it can never be assumed that a binary 1 equals "enabled" in all cases.
Removes the switch in the cluster which I didn't think was important at this point but I'm not sure so, good for it to be gone.
This should definitely NOT be done. He has a diesel truck and this would change the IPC to thinking it's a petrol truck. In both cases, FPALTD is disabled already.
Nice ?
Eventually the changes you make will make their way up to the mothership and become your new permanent ab data.
